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. 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.

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

  3. 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.

  4. 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: https://twitter.com/cleanmymac/status/1059797754849955841?lang=en

  5. 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!!!

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. Extremely disappointed that you deleted older videos with more features, i remember an older video that you had that shows how to truly disable some of the default apple apps like weather, stocks, etc.. and some other things to make the mac run faster, now it seems like you only seem to promote "free" trial apps that claims to clean the mac to free up space and have to pay, etc… i miss the old videos that you used to show how to disable things to make it use less ram, or something.. i forgot what it was but it was extremely helpful.

  11. I've been using Clean My Mac 3 for some time and it has been extremely useful. The other tricks are also very helpful and your video has given me the confidence to use most of your tricks. Many thanks.

  12. David i have problems with my internal speakers playing up after upgrading to mejovi ive spent 2 weeks on and off with apple on the phone no joy just wondered if by any chance you had any ideas ive done everything

  13. I had 6.62 GB left on my Hard Drive, I used the program and found large files and ended up with 111.98 GB gained , I found a lot of old GoPro Videos

  14. This was very good. I was having trouble with email and connecting to the Internet. I would have to restart 1-3 times a day. Now things are working much better. I'm not sure of the purpose of the final step, which is the remove the programs I just installed.

  15. Hi I have safe finder as home page and also when opening new tab in chrome and don't know how to get rid of it. It doesn't show as an installed extension, I installed an app outside of apple store that had a fake flash player installation option. Any options? Thanks

  16. Looks very helpful n I shall certainly try this. My concern of using scanning software is will they also scan your passwords?

  17. 2019 – 😍😍😍 Thank you!!!! Only half way through and already got back over 100 gigs (hiding in downloads👀) !!!! Thank yoooou!!! 🙂

  18. This App sounds amazing but pls read the reviews here and let me know your thoughts: https://discussions.apple.com/thread/8281867

  19. Why is it taking so long to empty the trash can? It’s been an hour now – is it because there was 18.71 GB of trash? Also, in the IOS file, I delete the phone backup file but it doesn’t go away? Am I just going faster than the delete file can go?

  20. I have a 2014 MacBook Pro with a 250 GB SSD. Before manually cleaning my Mac, I had 63 GB available. After cleaning I have 161 GB available.

  21. My iMac has less than 20% of disk space used and is slow as a turtle. As for this "class", I find it more of a commercial for Clean my Mac 3, a software I tried several years ago and still regret doing because in spite of uninstalling it, it keeps reminding me to clean… my Mac. Piece of scrap!

  22. Great video.. but are you saying. That I am going to have to pay for download an application to properly clean my mac? Am I not able to do this manually?

  23. Starting off by telling people to turn off File Vault is not good. Most corporations require that the drive be encrypted for IT Security.

  24. dear David , how can I remove "other" from my ssd , (I'm running Catalina 10:15 beta) without messing up my said SSD ? thanks your video's are well good

  25. 150gb. So I have music files in documents and in iTunes. After they are in iTunes can I delete the files in documents and if I do will they still be in iTunes?

  26. 34 GB Free out of 120 GB. By the way "YOU ARE, GENETICALLY ENDOWED WITH-GREAT TEACHING SKILLS", convey the latter to your parents. I enjoyed your "Apple Teaching", Thanks

  27. Hi, I know that long time old and continuous usage can slow a mac down and lot of other factors can contribute to degrading mac performance. We can also do something manually like delete large unused files, old app that no longer used, and duplicate data on hard drive. Upgrade mac hardware and firmware etc. We have alternative option too like Stellar Speedup Mac. I have used and found that this tools remove the trash, leftovers and manage the extensions from the mac. Complete uninstall all the unused application simple drag and drop option.

  28. I deleted all the iOS backup files (totalling 240GB!!!) but now they appear as "purgeable" data and still take up 240GB of space. I have no idea how to permanently delete the purgeable files. HELP!

  29. Hi David, love your stuff, just downloaded Clean My Mac – brilliant. However, I have a late 2014 iMac and when I'm on Safari or Chrome in a full screen video, I intermittently can't use the controls at the bottom of the screen, when I click on them, nothing happens, I have to minimise the video to click on the controls, sometimes the controls disappear altogether. Is this something you have come across? Keep up the good work! Jarod, Southwell, England.

  30. when I turn on macbook air 50% memory is empty, but when i use my mac its become full and get heat as well, what to do for it?

  31. Both before and after doing these things, I have 965 GB AVAILABLE out of 1 TB. Maybe it's because we're old, but we still save so much stuff in real, PAPER folders, etc and because we don't know HOW to download or save stuff!! Usually I "save" something and can never find it again.
