How to clean up a Mac: 4 top tips

Had your MacBook or iMac for a while or just use it a lot? If so, you may have noticed a change in its performance. Even if you're doing most things right, junk files, background processes, and other things can easily stack up within your machine and potentially slow it down. If you've been searching "clean up Mac" online, stay where you are. Here are our 4 top tips, including something that might surprise you. 

Turn off 'FileVault'

'FileVault' is an in-built app for macOS that encrypts all the files stored on your Mac's hard drive. This also means that any new files you create or download onto your Mac are treated in the same way (protected by a password). This is good news if you worry about someone gaining access to your Mac's files or data.

The downside is that 'FileVault' can easily sap power from your Mac's central-processing unit (CPU). Older Macs, especially ones not using SSDs, are the most likely to be hit by this problem. Turning off 'FileVault' can speed up your Mac. To do this, go to the Apple icon, 'System Preferences,' and then 'Privacy & Security'. After this, vTurn off 'FileVault'Turn off 'FileVault'isit the 'FileVault' tab. You can switch it on or off here. If you've had it on up to this point, please be aware that turning it off could trigger a lengthy process of decrypting your data.

With this in mind, if you want a simpler, faster method of improving your Mac's privacy and performance, it's worth saying here that CCleaner for Mac can certainly help with your privacy and security. Our app is also purpose-made to clean up Macs and has many features.

Investigate your hard drive

Your Mac's hard drive needs about 10-20% of its free space available to help macOS work properly. Before you head off elsewhere typing in things like "clean up Mac hard drive", there's an easy way to check for a problem.

Go to 'About This Mac', 'Storage', and then 'Macintosh HD'. Once you've done this, visit 'Manage' and then 'Review Files'. You'll see three tabs for 'Large Files', 'Downloads', and 'File Browser'. Simply put, these tabs give you a summary of the files stored on your hard drive and how much space is being taken up. Click the tiny drop-down menu tab called 'Size' to sort these files and find the biggest offenders. It's possible to easily delete files that slow down your Mac.

This in mind, it can require some investigation on your side and could end up being unnecessarily time-consuming. The good news is that CCleaner for Mac allows you to clean up a Mac from one app. To save you time and effort, you can use it to easily find and delete commonly overlooked temporary files and folders needlessly taking up hard drive space that could be put to better use. 

Uninstall some apps

If you've installed multiple apps on your Mac since you've had it, this is something else that can also slow it down over time. Again, you can check how much space apps are using via the hard drive investigation method we went through earlier. Like how you might treat a smartphone, if there are apps on your Mac that aren't essential to macOS and you never use them (be honest), you should probably delete them.

So, if you've been hitting up your favorite search engine with things like "clean up Mac hard drive", then finding the courage to get rid of some apps is another good tip. You can easily drag apps into macOS's 'Trash' folder, but this doesn't fully get rid of them. In fact, even when macOS deletes files it still leaves traces of data behind.

So, it's a good thing that CCleaner for Mac has a way of fully cleaning deleted files. Something else worth sharing is that our app makes the whole process of uninstalling stuff a lot easier for you. Rather than you having to jump between different folders to find apps, CCleaner for Mac allows you to view them in one place. Another great feature is that it can remove the configuration files normally left behind after an app's deleted, something that macOS usually doesn't touch. 

Now it's time for our big reveal. Perhaps you can see what we've been building up to.
