How to Clean Your Mac 2019

How to Clean Your Mac 2019

Hello, everyone. David A. Cox here with Tech Talk America,
and today, I’m going to be teaching all of you at home how you can easily clean your
Mac. Now for those of you out there who’ve watched
my little tutorial videos over the years, in the past when I’ve taught this class, I
taught you manually how to go to every nook and cranny and find everything and clean it
out. I’m not going to do that today. I’m going to give you a bunch of different
tricks, but what I’m going to really focus on today is featuring a piece of software
that can not only help automatically go to those places and find that junk and clear
it out, but also in addition to that, we’re going to talk about the things that you can
do to keep your Mac running efficiently so that it runs faster in general, and that’s
going to be tricks for everyone. So even if you don’t get the software that
I’m going to recommend, this is still going to help you. So, I hope you enjoy it and, by the way, links
to everything you need, you’re going to find down below in the description of the video. How to clean your Mac, coming up next on Tech
Talk America. All right, folks, so the first thing I would
like to ask you to consider doing is before we get started here, take a look at how much
free space you have on your Mac right now. If you’d like to participate, you know I encourage
participation. Leave me a comment down below. Let me know around how much space you got
back by the end of this class. So, the first feature we’re going to go over
is something that you may have at one point accidentally turned on during a system update
to your Mac, and that feature is called File Vault, and if we turn it off, you’re going
to be amazed not only at how much free space you get back but also how much faster everything
runs. First let’s figure out if you actually have
it turned on. So, let’s go to the little Apple icon that
we have here at the top left corner, and we’re going to go in to System Preferences. From here, we’re going to go into security
and privacy. Now from here, we’re going to go into the
second tab, which is File Vault, and you’ll notice that on my screen currently, A, it’s
grayed out, and B, it says turn on File Vault. If I wanted to enable this, I would have to
first click the little lock icon down here and then type in the administrator password. However, that’s not what I’m going to recommend
to a lot of you. What file vault basically does is it encrypts
all of your data so it’s much, much more secure, but the thing is is that the main type of
security that at least I tend to think a lot of people should be more concerned about is
their passwords, not so much encrypting their local data. That’s not as big a problem. Now if you’re a high-profile person, and I
have a few clients who are, yeah. Then in that case, this is probably a very
good idea, but otherwise, I think you should probably consider turning it off because in
the process of doing so, it’s going to dramatically speed up your computer, and you’re also going
to get back a very significant amount of space. I just did this yesterday for a client of
mine actually, and she ended up getting back over a hundred gigabytes just from doing that
one little trick. Just be aware that if you currently have it
turned on and then decide to turn it off, it has to go through a very lengthy process
of decrypting all of your data. So, it is the kind of thing that you might
want to consider doing overnight since it can take upwards of, I’ve seen, eleven to
twelve hours. The next thing I want to do is I want to kind
of show you where to go in general to diagnose where is your clutter problem coming from. So, let’s go to the Apple icon at the top
left and go to About This Mac. From here, we’re going to go to the third
tab, which is storage. When you’re looking at this graph, and it’s
going to take a minute to kind of assemble it, it’s going to give you a kind of a layout. You can put your cursor over it, and it’s
going to say, “Okay, you’ve got this much documents. You got this many apps,” et cetera. In general, the thing to know about this graph
is you want to always make sure that at least 20% is available. If you have less than 20%, it is very normal
to experience apps crashing and to get that little spinning beach ball some people call
the spinning beach ball of death. Cute, right? What I want to do is, over the course of this
next little chapter, I’m going to show you how to go through and kind of start to diagnose
each of those because for a lot of people, it’s like they have one thing that they do
a ton of. So, what we’re going to do from here is we’re
going to go into manage, and this is going to get us some really awesome tools that we
didn’t have until recent years in the operating system, and we’re going to start to be able
to find where is the [phonetic] [04:32] bloatage coming from. From here, let’s go into review files down
at the bottom right. On this screen, you’ll see we have three different
tabs at the top. We have large files, downloads, and file browser. So, depending on where your clutter problem
is coming from, this may help you. Although as you will see momentarily, this
actually did not find everything. So here under large files, it’s looking for
individual large files, and so my advice is to organize this by file size, and then if
there’s anything here that you really don’t need, if you put your cursor over it, you’ll
notice there’s a little X that appears right next to it. If you click that X, it will immediately delete
it. Please note, it does not go to the trash. It’s gone immediately. If you need to find out where the file is
coming from, you can click on the little spyglass icon next to it. Next, if we go here into the Downloads tab,
you’ll see what it’s really looking for here more than anything is DMG files. So DMG files are typically very large. They’re used to install software that you
downloaded from the web, but if you have DMG files on your computer, once the software
is installed, you really don’t need them anymore. So, this is typically something you can pretty
safely delete, and then we have file browser, which is just going to show you kind of a
layout of where is everything coming from. Let’s go through a few other little tricks
to get back some space. One I want to talk about is right here, which
is iOS files, and if you see anything in here, let me just kind of tell you generally speaking
what it is for most people. If you see anything in this list, it’s going
to be old backup files of your iPhone and/or iPad, or even possibly, I don’t even know. iPod might even show up on there. Here’s the thing. Back with the way that iTunes used to work,
this is really before iCloud got involved, you tended to have a backup file of your phone
and other devices on your computer. Now because of iCloud, there really is no
need for that. So, for the most part, you know you can pretty
much take anything that you see in this list, and you can wipe it out, and typically those
files tend to be a few gigabytes a piece. So that alone should help you out a little
bit. Next one we have here is iTunes. One of the things that’s important to remember
about iTunes, this goes back to something similar with iOS, is that a lot of times when
people would have something like an iPhone, they would plug it into their computer, right? When you did that, there was an option back
in the day to where you could tell it to sync apps, and so for a lot of you out there, you
may discover that you actually have a copy of those apps on your computer. If you want to kind of find out where that
really is, let me just show you where to go here. So, you’d open up Finder, you’d go into your
home folder, the one with a little house icon, and then in there, you go into music, iTunes,
and it’s going to be in here. I believe it’s mobile apps, something like
that, and for the most part, you can pretty much delete anything that you have there. There’s some other things to keep in mind
also about iTunes. Like for example, you might have old podcasts
laying in there that you can now delete. That may have shown up on some of on the previous
screen where it’s giving you the recommendations. Another one, very common for a lot of people
they can clear out, is GarageBand. You know, I wish more people liked GarageBand. I think it’s actually kind of cool, but admittedly,
I don’t really even use it all that much. I tended to be more of a video guy, but if
you don’t use GarageBand, you may have some sound files that are on your Mac, and frankly,
they’re actually quite large. So, if you want, you can just click remove
GarageBand sound library and get rid of those. All right, everyone. The next tool that I want to show you does
a few different things. In general, we’ll just kind of find some of
those junky files and allow you to save a little bit more space, but the other thing
that it does is it gives you a bunch of different tools that just help your Mac run a little
bit more efficiently. It is a paid piece of software, but if you
want to try it with no obligation, there is a direct download link in the description
of the video, and what you can basically do is run it and just see if it finds anything. Again, that’s really only part of the software. The other part here is about keeping it running
efficient for the future. So that’s where I would tend to recommend
it. The next piece of software that we’re talking
about is called CleanMyMac 3, and when you first load it up, the first thing you’re going
to do is hit scan, and it’s just going to go through a bunch of different locations
on your Mac, looking for those junky types of files. Now granted there is going to be some overlap
here with the previous method that I just showed you, but as you will see, it actually
finds files that Finder didn’t find. I know. I find that statement very confusing. Finder didn’t find it, but anyways, you get
the idea. So, I’m just going to kind of let this crank
through. Keep in mind, this is a demo account, so it’s
probably not going to be nearly as dramatic as it would be on your computer. So, we’ll just let it finish up, and as you’ll
see, it’s going through fairly quickly. We’re at under a minute right now. So just going through, doing its thing. The thing that you’re going to be most impressed
with, I think, is the large and old files. Now just to refresh your memory. So, it’s saying it found nine gigs available
for safe cleanup, but if you check this out here, large and old files, it’s actually found
325 gigabytes of additional files that I might be able to dump. So, as we go through here, the first one we
have is system junk. Things like old cache files, logs, et cetera. For the most part, these are pretty safe to
dump. So, without a problem, hit clean. Photo junk. I’m not going to go into a big explanation
of this, but my recommendation is do not run that feature. You can see any of those old attachments that
are stored in your computer right here. iTunes junk, similar to what we went over
earlier, but this actually does find some other stuff that you wouldn’t find just probably
by poking around through the iTunes folder, and of course, this does it a lot easier. So pretty safe. You can hit the clean button here and get
back whatever you want. Trash bins, yeah, this part doesn’t really
do much. It’s just emptying the trash, and then we
have the last one here, which is large and old files. Now, I want to just kind of refresh your memory
here. If we go back to the previous screen. Oops, sorry, that was memory. Storage, manage. It told me on the Mac that the largest file
I had was 3.75 gigabytes. Hmm, funny because this shows another file
that is 60 gigabytes, which is the library folder, which would be a very, very significant
sized file to forget about. So, as you can see here, CleanMyMac 3 does
do a better job than just the built-in tools in your Mac. So through here, you can go through and use
these tools to find the largest and smallest files and clean them all up, and then you’ll
see down here at the bottom left, we have a few different utilities to help keep your
Mac running efficiently, and some of these really, you don’t run so much through the
app. They just kind of run in the background. The first one here is the uninstaller. What’s great about the uninstaller is if you
go and just trash an app, it automatically goes and it finds all those little hidden
library files and cleans those out as well. Very nice tool to have. The next one we have here is a maintenance
tool, and well, some of these you can do right through your Mac. You would have to manually go through and
do each one of these one at a time, and with this, it just does all of them at once. So, the idea here is you might want to probably
consider doing this at night. It is going to typically take a little bit
longer. Good idea in general, maybe, to run this once
a month, maybe once every other month. Privacy, so things like your browsing history,
your download history. You can just go through here, check these
items, hit remove, boom, they’re gone. Also, things like passing iMessages history,
recent things that you’ve opened on your Mac, these really don’t take up so much space. This is really not necessary. Extensions. There’s a whole bunch of different extensions
here that talk to your computer, but it is a good idea to just kind of go through these
and just make sure that they are all legit. The one that I would especially recommend
that you spend some time on is the Safari extensions, or whatever web browser you have
and the extensions. The reason why I point this out is this is
how adware can hide on your computer. Not exclusively, but that’s one of the places
where it can hide. Then the final tool that we have here, I absolutely
love, which is called the shredder, and it has a couple of different features that it
uses, and I want to just give you a real-life example of how this saved my butt. So, I, like everyone, occasionally make mistakes,
and I accidentally deleted a file about, or tried to delete a file, about two years ago. It caused this giant mess on my Mac, and every
single time I went to empty the trash, it gave me all these little notifications, and
I had to hit continue about literally 200 times just to empty my trash. I was on the phone with Apple, and there was
just no good method to be able to clean these files, and the shredder tool did it in two
seconds. So, a very, very good tool. It runs in the background, and when you go
to delete certain types of files that can absolutely give you problems if you just try
to do them without this software, this just makes it that much easier. As you will also notice here, there is a feature
to individually select a specific file and immediately go through and scrubs that data
clean. So, with that, you just hit select files,
point it to wherever your file is, and then it’ll, boom, wipe it out clean. All right, folks. So, the last trick I have for you is if you
open up your Finder window, I want you to go to your home folder, go into your pictures
folder, and in this case here from demo account of course, we see just a Photos library. Now for quite a few of you out there, you
may discover that you still have on your computer your old iPhoto library. If that’s the case, basically let me kind
of explain what happened. For those of you who have been Mac customers
for a while, of course, before there was the application that is now known as Photos, we
had another older application called iPhoto, and basically iCloud was the big reason why
things kind of converted from one to the other. Also, in terms of making things a little bit
more consistent in the experience, and so what happened was your old iPhoto library
was then migrated into what became your Photos library. Now at this point, I would like to let you
all know that it is completely a normal reaction to have a massive anxiety attack just before
hitting the Delete key on your old iPhoto library. I get it. Everyone has a fear of deleting their old
photos. So, before you do that, let me give you one
last little trick that, if you want to, you can do just to make sure that you have everything. What you can do is if as long as you still
have iPhoto on your computer, you can still open your old iPhoto library, then go back
in time to your very first photos, and just get a visual sense of what they are. Then, quit out of iPhoto, open up Photos,
the newer software, and go back to that same period in time. As long as you see everything there, there’s
a pretty darn good chance that you have everything from there forward, and if you want to go
one additional step further, you might want to consider getting a really inexpensive flash
drive, if you need a recommendation, I’ll throw you a link down below, that’s big enough
to support your entire Photos library. So that would have, of course, the old data
and the new data. Then, just take your whole Photos library
and throw it on that flash drive. If you can, try to remember to update it a
couple of times a year and put it in something that’s preferably fireproof and waterproof. Thank you for watching, everyone. If you enjoyed this video, if you got back
some space on your Mac, I hope you’ll consider hitting that little like button. This is David A. Cox with Tech Talk America. I’ll see you next time. Take care, everyone. Class dismissed.

  1. Well I forgot that I bought this app back in 2016. So after watching this vid I remembered buying this and hunted through my old emails and found the link. Had to get a new activation code and got it up and running.

    Well I got back 150.98gb 😬

  2. Wish you would show me how to recover my Mac password. Somehow the P/W i was using does not work anymore?????

  3. Hi David I was watching your video on leaning your Mac, I had a hard time keeping up with you cause I could fine those step and just didn’t show it, not sure because on what operating software I have, but I have 2009 iMac using OS X YOSEMITE 10.10.5 I have 8 GB memory.

    Can you help me find these step you went through so I can follow the step and would really appreciate your help cause I notice my computer is slowing down and I haven’t done a major cleanup on my desktop IMAC If you can help me would really appreciate it very much
    Thank you Jim

  4. Hello David, Once again your wisdom helped me! I went from 48 GB free to 79 GB free. I only have 126 in the first place, so that's a lot! Thanks so much!

  5. I thought this video was going to be about the more important type of cleaning, the cleaning of dust inside it.

  6. Thank you David. I am a relatively new MAC user, I have a youtube channel, and my MAC system storage is really really high. This morning it was 312GB. I appreciate your terrific videos so much. awesome stuff. I will let you know how I do cleaning this up.

  7. Apple has a page dedicated on how to clean their products, e.g. „use a damp, soft, lint-free cloth to clean the computer's exterior“ – see

    “How to free up disk space” will avoid ambiguity, IMO.

  8. Thank you so much! I went from about 500 GB available to 1.74 TB available apparently just because I turned off the firewall!! Thank you so much! Shazam for real!

  9. Thx, love my Mac but I have to say it has the worst and most frustrating file management system out there!

  10. Thinking of replacing Windows 10 comp with iMac. Using less than 50% of 512 Gb. with Bitlocker. Wouldn't the purchase of a faster iMac than needed make up for the encryption slowdown? Apple rep says I need the cheapest model since I don't use online video games. However, I think the fastest non-Pro model with 1 Tb. in case I use Bootcamp. Please comment.

  11. David thanks much for your "How to Clean My Mac" tutorial. I started out with 221GB available on my Mac Pro. Ended up with 435GB available. This is Huge. Most of the large deletions were .mov .dv and a few .PSD formatted items. My videos were a hog. I've owned Clean My Mac app for 10+ years in various versions maybe more but your tutorial was incredible regarding freeing up storage space . Thank You.

  12. Good sound advice. I have had Clean My Mac 3 and just upgraded to version X. I have three external 2TB drives for double backup of photo files (RAW, they take up space) and one for Time Machine, which has saved me more than once when my iMac decided not to play nice…

    I also back up on DVDs but have found them not to always be reliable when trying to retrieve old files burned on a previous DVD burner. This is especially true if the DVD has a paper label that was attached.

    Between all that back up and regular clean up, there is minimum risk of losing data. Thanks

  13. David thanks for your clean and protect your iMac live, having watched the whole video I proceeded to follow your instructions and now my iMac working very much quicker and I have stopped receiving cautionary messages regarding my hard drive failing, Before I started to clean the iMac system which has a 1TB hard drive with only 1.46 GB available, after the cleaning process we now have 12.6 GB available thanks absolutely brilliant…

  14. The software that you recommended worked like a charm….Its awesome , all your tricks work, thanks !

  15. Something that worked for me with a difficult to delete file in the trash: do a restart. As soon as your desktop opens, hit empty trash. If you’re quick enough you can delete the file before it starts running on its own. Thank you for all the suggestions. Going to do some cleanup tomorrow 👍🏼

  16. So far I went from 506.92 free and now have 642.57 GB free. I only did the first part of the video. Thanks. Will see what else happens.

  17. If your system storage looks to be way too high, make sure that you delete any old user accounts that you don’t use. One of my old accounts was taking up 50GB!

  18. its just my system thats huge, i have 121.21 storage but now i have 5GB bc of my storage it takes up 98.99 GB ;c

  19. thank you, great- a little to fast for me to follow, but very helpful.

  20. This is gonna be the longest comment ever get your food and its gonna start in 3…2…1

    So this guy title is how to your iMac but i search "how to clean you iMac outside" but it showed how to clean your mac but its cleaning mac's HardDrive so this is really f up, what if you dont know what you wanna search and do on youtube but you can explain but you dont know whats it called so if you do explain it youtube doesnt give you a auto suggestion and when you search it it says instead of that its that but its wrong

  21. My 2yr old macbook pro uses 234 of my 250 GB storage – seemingly all in a CONTAINER file. I have very little stored on my computer.

  22. anyone else have problems with clean my mac? I used it for a few years but then one day for some reason the when cleaning my mac with the software it deleted all of my folders so everything was on just scattered on my computer, NO LITTLE BLUE FOLDERS ANYWHERE!!! I had to reorganize EVERYTHING! Total nightmare. I also contacted customer support and they had no idea how to help me nor did they do much. Careful with that software. I did get back 70 gigs here from the video! thanks

  23. Hey David, question about the iOs Files (which basically are backups of my iPhone), I'd like to know how to transfer this data from my computer to an external hard drive. Thanks so much! Cheers

  24. Great video! Just a warning before downloading any software to clean your pc or mac. Was about to download one that had great reviews and had a free trial. Happened to click on the privacy policy to read about how they use your data. This company actually stated that in addition to sharing data with government and law enforcement when necessary, your info would be available to third parties to determine future employability, and other very scary statements. The “government and law enforcement” was expected, but not the other info. Some websites discuss these privacy policies and how they are different with free services in comparison to paid, but I read MacPaw (owns Clean My Mac) privacy policy, which also covers it’s products, and I would recommend a thorough read about how your data will be used (in light of the new privacy policy disclosure laws) and decide if this is ok with you before clicking on accept. Otherwise, manually cleaning up your mac may be the way to go.

  25. Quick and easy in only 2 steps
    1. Pick up your Mac
    2. Insert Mac into your garbage bin
    Success your Mac is super clean and your Mac is so clean u can’t even see it thank me later

  26. I totally love your videos… I found you as I was looking for some info on using final cut pro… I am working my way through your other videos now… thanks so much for sharing your expertise! In the spirit of contributing and following along, here are my Macbook stats getting started…
    Available: 113.36 GB (113,356,963,840 bytes)
    Capacity: 1 TB (1,000,345,825,280 bytes)

  27. Managed 33GB, well worth following. The “free” cleanmymac3 download suggested by David though wouldn’t complete the clean action without me buying the software. Shame.

  28. Hi David, thank you for your videos , my mac is older so i don't have the same screen then you do, Do you have videos from and older vision of mac. I have and MacBookPro, I am not sure what year it is. Can you help ? Thank you in advance. Tina

  29. I used the ccleaner and my internet fios gig speed slowed down to 70mbps. Plus I found malware installed. I would not use ccleaner.

  30. David: I started the cancellation of the filevault and the turning off of encryption. It has been running for over 12 hours. Long story short I would like to go back to encryption. How do I accomplish that? Do I have to wait until the mac is done first? Many thanks.

  31. “Gigs” is pronounced as “Jiga” which is the Greek genus from which the word “Giant” or “Gigantic” comes from.

  32. Turning off FileVault returns a negligible increase in performance that you will not even notice in newer Macs. Maybe old ones but not necessary at all with newer Macs ~ 2017 and above.

  33. This video was great until I figured that there was no way to disable one helper process called CleanMyMac X HealthMontior. You cannot even quit this process using Mac's activity monitor. Here is their explanation associated with this matter:

  34. Wow! I was in grave danger of losing my computer and just went from 2.51GB free to 305.03GB free. AND I still haven't done the Filevault trick, which I'll wait to do overnight. Thank you thank you thank you!!!

  35. CleanMyMac don't give you an option not to upgrade when they updated the app. You cannot use the existing app unless you choose to upgrade.

  36. Ok, listen. An ad for your video has been popping up in my feed for a while now. I'm finally watching it. I hope you're happy.

  37. Beware of trashing iOS app files (.ipa) from your mobile applications if they are no longer available in the App Store. You will not be able to get them back.

  38. Forget about the “library“ folder? Are you a complete moron or is this just part time idiocy? OS X didn’t list the “library“ folder because that’s basically your system drive you dumb expletive word. You should not be telling people what and what not to delete because if they delete that library file they better have a back up or you need to drive where ever they are, kiss their feet and pay for a brand new MacBook Pro because you suck.
