1. Empty Trash Bins

This is a fairly simple technique but is overlooked by a lot of people. The Trash is similar to Windows PC’s Recycle Bin. Thus, once you delete files within your macOS computer, it is moved to the Trash in case you change your mind.

To remove these files permanently, you must empty the Trash on your Mac computer. However, it is important to note that macOS computers “may” have multiple Trash folders within it. As such, you may have to empty more than one.

In order to empty the Trash, simply right-click or press CTRL + click on the icon for Trash. Choose the option to “Empty Trash” afterward. This will help you delete all the contents moved to Trash from the macOS computer’s Finder.

Empty Trash Bins

Mail, iMovie, iPhoto has Trash cans of their own. Thus, if you have deleted some files from these applications, you have to empty their own Trash cans too. These involve fairly the same steps. You have to right-click the Trash and select Empty Trash.

2. Uninstall Unnecessary Applications

Of course, every app would use space on your Mac. So, if you want to know how to free up space on Mac, then you must learn how to uninstall apps. To do this, you simply open a window for Finder. Select the Applications within the sidebar.

Click and hold this click on an icon for an app. Then, drag it towards the Trash and drop it there. After that, you can empty the trash to make sure it’s gone. The problem with uninstalling apps on Mac is that they have leftover files.

Uninstall Unnecessary Applications

There are manual methods of removing these leftovers. However, trying to delete them can be risky as you may delete system files necessary for the operating of your macOS computer. Thus, it is recommended that you use PowerMyMac’s Uninstaller utility to completely remove an app from your system.

3. Clean Out Unecessary Files In The Downloads Folder

Similar to emptying Trash, this method is very obvious. To know how to free up space on Mac, you should remove unnecessary files. Your Downloads folder is filled with a lot of files you don’t need. To find this folder, you simply have to open “Finder” and then locate the folder for “Downloads”.

Clean Out Unecessary Files

Check out which files you don’t use. You may have a movie you’re tired of watching. You may have installation files you don’t need. Clean up the mess and try to organize the most important files into folders that make sense.

4. Delete Temporary Files

In order to implement the best possible technique on how to free up space on Mac, you should delete its temporary files. These files are clogging up your system and taking up to much space. macOS usually removes these temp files automatically.

However, there are times when it doesn’t do its job perfectly. Heck, no system is absolutely perfect! For instance, a web browser gives you the ability to clear your browsing data. Other temporary files can be seen by opening Finder.

Then, you should visit Go and then check out Go To Folder within the menu in order to be able to type in ~/Library/Caches to visit your cache folder. It will display a folder that has a lot of subfolders in it. You can manually delete temp files if you wish.

However, we would like to reiterate that this method is not recommended. This is because you may delete temp files that are important to your documents, work files, and even the entire system. As such, you may use PowerMyMac to clear out temp files within your computer.

5. Clear Out iTunes Backups

If you have multiple devices from Apple, then you may have backups within iTunes. These backup files of your iPad or iPhone take up a ton of storage space. Some people have even deleted hundreds of gigabytes of data just from these backups.

In order to delete them, you should go to the path without the period in the end: ~/Library/Application Support/MobileSync/Backup.

Again, an easier method of cleaning up your backup files on iTunes is to use PowerMyMac. You can simply select “iTunes Junk” within the Cleaner module allowing you to delete unnecessary iTunes backup files within your system.

6. Delete Language Files

There are Mac apps that have different language files that they actually support. However, you know that you use only a single language within your macOS computer. As such, you can use PowerMyMac and select the System Junk folder in order to delete language files within your computer.
