Even with all of the space some Mac users can enjoy — depending on the size of the hard drive you bought — they always run out of room eventually. Sooner or later, a Mac starts to slow down, even overheat, and the space you need is no longer there. Here are ways you can free up space when your Mac hard drive is full.
How to check Mac hard drive space
To start with, it always helps to know what is taking up so much space on your Mac before you start deleting files and folders.
- Go to Apple menu > System Settings.
- Click General and then Storage.
Another way to see what is taking up space is within System Data and User files. Next to every folder and application, your Mac displays how much space everything uses and, therefore, makes it easier to judge what to delete.
What system files can be deleted safely?
Depending on your user habits, there could be tons of various junk on your Mac. Some of it can be safely destroyed because these files are either outdated or have never been used.
How to find your biggest space hoggers
Yes, you could spend a few hours in Finder sorting your archives and documents. The problem is all folders in Finder look the same. Is there a quicker way to find out where is your space going? Yes, and it's called "Space Lens."
Space Lens is an amazing little tool that is a part of CleanMyMac X. It creates the interactive map of your storage, so you can explore it and at a glance see the largest space wasters — a quick way to see what is taking up so much space, and then in a few clicks, remove anything taking up too much room or that you've forgotten about and need to clear out.
- Get CleanMyMac X for free.
- Open the app and click Space Lens in the sidebar.
These "bubbles" are your folders of different size. You can even find the folders that are regularly hidden away.
How to clean up Mac hard drive space?
Here are a few tips that would help you to unload your hard drive.
1. Delete unnecessary apps and games
Most of us will have games, apps, and other content that is no longer needed taking up hard drive space. Even Macs with as much memory as some of them are equipped with run out of space eventually. If "Your disk is almost full" is a problem you've encountered, you need to follow these steps to free hard drive space on a Mac.
Go to the Applications folder.
Search through and see what you don't need anymore. Make a list of these because once they're out of the Applications folder, there is a chance you need to check in other places around your Mac to find other traces of the same apps, in case there are folders and system files stored elsewhere.
Drag and drop the unwanted apps and games into the Trash.
And then, search in Library and other hidden folders for other traces and elements of the apps and games that you've deleted. Once you're sure you've got everything, empty the Trash. It is also worth restarting your Mac just to make sure you've removed everything and your Mac is operating at peak performance again.
2. Watch out for backups
Another problem that is commonly encountered on Macs are backups from iOS devices. Although most backups are now done in the cloud, there are still millions of Macs with iPod, iPhone, and iPad backups still taking up hard drive space.
To find them, go to Finder > Go > Go to Folder, paste the following path, and press Return:
~/Library/Application Support/MobileSync/Backup
Now you can take all of these unnecessary backups to the Trash, then empty it to free up space.
3. Empty Trash and email downloads
Another way to free up much-needed space is to empty to Trash and clear out months or years' worth of email Downloads. Once you've emptied the main Trash on the right side of the Dock, it is also worth checking in the Photos, Mail, and iMovie applications — if you've used any of those recently — as they also have their own Trash functions, so make sure to clear those out too.
Whether or not you use Mail or a third-party or browser-based email application, downloads go into the same folder. You could be sitting on months or years' worth of downloads.
To see your Mail Downloads:
Open Finder, choose Go > Go to Folder...
Type in the following path and press Return: ~/Library/Containers/com.apple.mail/Data/Library/Mail Downloads/
See what's inside and delete it if necessary.
4. Free up more space with CleanMyMac X
These are several third-party tools you can use to create more space on a Mac. It's entirely up to you to find the best cleaning partner for your Mac — but beware of scam Mac cleaners. When you see the "Your Mac is infected" message, don't fall for it — it's a trap.
But that said, there are also reliable junk removers, like CleanMyMac X. For example, CleanMyMac X is notarized by Apple and doesn't contain any malicious components.
Here is what CleanMyMac X can clean on your Mac:
- Large & old files
- System junk
- Unseen applications
- Mail attachments
The user interface looks like this:
According to the developer's site, an average user locates up to 74 GB of junk to clear out using the app.
CleanMyMac X is available for a free download here.
Okay, we've told you how to delete your apps, games, photos, and other folders taking up space. Hopefully, you can get your Mac working at peak performance again.
