Hi, this is Gary with MacMost.com.
Let me show you how to properly uninstall applications on your Mac if you're running
macOS Mojave or one of the versions just before it.

This is one of the most frequently asked questions by Mac users.
How do you uninstall an app?
It's very easy to do if you've got the app from the Mac App Store as I'll show you in
a minute.
But you can also uninstall apps on your own no matter where you've gotten the app.
However, a lot of Mac users see ads or hear about some sort of cleaning app or uninstaller
app and they add this to their Mac They're trying to remove something from their Mac
but yet they're adding something to it.
I highly recommend that you do NOT ever add a cleaning or uninstaller app to your Mac.
Most of them are really bad.
Some of them are actually just malware in themselves.
Just never install a cleaning app on your Mac.
Even the ones that are harmless aren't really doing much for you.
macOS takes care of itself and has for years.
But there's this mindset that people have from back ten, twenty years ago that operating
systems need extra utility apps to run properly.
You don't need a cleaning app on your Mac.
Just don't install them.
If you need to uninstall an app I'm going to show you how.
For any app that you got from the Mac App Store it's easy to uninstall.
You just need to launch Launchpad which you should find here in the dock.
It brings up all your apps.
You can use your trackpad or mouse to swipe between pages.
To uninstall apps just click and hold any app.
It doesn't matter which one.
I'll do it for Pages here.
After a second you'll see all of the apps start to wiggle.
Some of them will have these little circles with an x in them.
That's how you uninstall an app.
You simply click the circle with an x, it uninstalls the app, and you're done.
Notice the some apps do not have an x.
There's two reasons for this.
One is the app is part of the operating system.
So these here are all integral to the operating system.
You get them when you install macOS, not separately, so you can't uninstall them.
If you don't want these apps there simply don't use them.
You can hide them in an app folder if you want.
But they are part of the operating system so you can't delete them.
Another reason that you might not see an x there is if the app was installed from somewhere
else besides the Mac App Store.
So, for instance, ScreenFlow here and Audacity were installed from other websites where I
downloaded an installer and installed the app.
To uninstall these you're going to have to try a few different things.
So the first place I usually go to figure out how to uninstall an app is just to go
to the developer's website.
So you should only be downloading apps from the official developer website.
Never download an app from any kind of downloads site that has all sorts of different apps
or something like that.
Only ever download from the official site of the developer.
Make sure it's a developer you trust or you shouldn't be downloading at all.
Then when you go to a site like that, for instance let's go to a trusted Mac developer
called Panic that makes some great software.
They've got, basically, a support section here at the bottom.
It's pretty easy, when it's a good developer, to find their support section.
So you can go Get Help With, and we'll do the app Transmit, which is what I use to FTP
to my servers.
There are a bunch of different articles and things here and Search and sure enough if
I search for uninstall I get a great article on how to completely uninstall Transmit.
So it gives me step by step instructions of exactly what I should do.
This should cover 80-90% of any app that you install from another site.
You should be able to go to the developer's website and see exactly how to uninstall it
and follow a couple of quick instructions.
There may even be a little uninstaller that you could download, run, it does it for you,
and then you delete the uninstaller.
Even though Panic itself recommends an app cleaner here for uninstalling I still say
do not download app cleaners.
Just follow these instructions.
As a matter of fact you should look for uninstall instructions when you install an app.
Don't install any apps that don't make it very clear about how you uninstall it.
They don't include an uninstaller or instructions on how to get rid of it.
Here's another great developer, Smile software.
If you search the knowledge base on their site you quickly come up with an article,
for instance this one on how to uninstall TextExpander.
They tell you exactly what you need to do and even do it for older versions as well.
Any good developer is going to have this information on their site.
So a lot of times these uninstall instructions are simply going to tell you to go to the
Applications folder.
So in the Finder here we'll do Go and Applications, find the application in the list, drag it
to the trash, and Delete it.
This is, indeed, a great way to delete apps.
Most modern apps won't really install anything else outside of the app bundle itself so just
by selecting the app, dragging to the trash, and deleting it you've uninstalled the app.
But in some cases apps will install extra components in your System Library.
Now this is getting rare.
It used to be very common.
In future versions of macOS it's really going to be hard for developers to fall back to
installing things in the library.
They're going to have to put them inside the app.
But for now, if you really want to go and see if there are any extra components left
over, it's pretty simple.
You want to go to the Go menu and hold the Option key down which reveals Library.
This will take you to your System Library for your user only.
So not for the entire operating system.
In here you'll see a bunch of different folders.
One of them is called Application Support.
Go into that and you'll see a whole bunch of different folders.
It's pretty quick and easy to identify which folders belong to an app.
Here's one for Adobe.
Here's one for Audacity.
Here's one for BBEdit.
All sorts of apps that you may have installed.
You can also look for com. and the company name.
Dot and the name of the application.
Go through these and if you see something that you're absolutely sure belongs to an
app that you're uninstalling you can simply delete that out of your library.But in many
cases what they've stored here is pretty small.
Exceptions are things that deal with lots of media.
Like maybe a music creation app may actually install a ton of audio files there.
Or a video editing app may install lots of backgrounds and special effects into a library
folder.
So sometimes they could be big but most of the time it's pretty small.
Also if we go back up to the Library level there's a folder called Preferences.
In that you'll also find files that have to do with the app.
These will usually be in the com dot company name dot app name format.
So look for what you want there.
These are typically really small files.
So if I look here I could see some of them are just a few bytes in size for instance.
Others are really tiny.
Worrying about these and getting rid of these, it's kind of like if you're worrying about
the gas mileage in your care and you know that's affected by the cars weight, worrying
about how much dirt is on the bottom of your shoes, right.
Do you clean your shoes off before you get into your care to reduce your gas mileage
by a teeny, tiny, little bit.
Probably not.
So something like a file that's taking up 119 bytes is not something you should worry
about.
It's not worth poking around in your library folder to go and get rid of files like that.
These files can be useful if you decide to uninstall an app to save space and install
again later then you get your Preferences back which may even include, like, a license
number for that app.
So I typically never worry about the Preferences file.
Now another way to uninstall an app by going to your Applications folder is to look to
see if the app is inside a folder.
For instance here's CamTwist.
It's inside a folder.
Sure enough if I look there, there's an uninstaller there.
So I can run that.
This is just a simple set of command lines that will uninstall one little extra library
file, as well as the app itself.
But sometimes there's a more sophisticated uninstaller that will remove certain parts.
So there's an order to this.
If you want to uninstall an app the first thing you should do is try to do it through
Launchpad.
If you can do it there, great, you're done.
Next I go to the developer's official website and then I look at their support documents
and search their site for uninstall instructions.
If there are instructions there I simply follow the instructions, step by step, to uninstall
the app.
If that doesn't work out then I see if the applications' installed in a folder in the
Applications folder and if so if there's an uninstaller included there.
If that fails the next thing I do is drag the application from the Applications folder
to the Trash, look in the Library folder, look at Application support to see if there's
an obvious folder or set of files that definitely belong to that app and get rid of them.
If I really want I can look in Preferences as well for something that obviously belongs
to that app.
That's it!
That should cover 99.9% of all apps.
If there's an app that can't be uninstalled using any of those methods it's a really bad
app.
You should probably search forums and things for other ways to uninstall that app.
There are probably other people that are talking about it as well.
In general you should be careful when installing apps.
You should only install apps that you absolutely need, from sites you absolutely trust.
Also, get in the habit of making sure that you know how to uninstall the app before you
install it.
So look at the developer's site to see if there are clear instructions on how to get
rid of the app if you decide you don't want it on your Mac anymore.
