How Much Free Space Should I Have on My Mac?

Studies have shown that your Mac's performance begins to degrade when storage space usage reaches 85%. To ensure proper functioning, it's recommended to have at least 10GB of free space. However, maintaining at least 15% of your storage space free is even more advisable.

Now that you know how little space you can use, let's take a look at how to free up disk space on your Mac.

The easiest way to free up disk space is to use the built-in disk cleanup tools on your Mac. You can easily find them by clicking the Apple menu > General > Storage > Recommendations.

3. Uninstall Apps You Don't Use

You probably have a ton of programs installed on your Mac. Is there an application that you have only used once? Those unused applications are eating away at the highly needed space you want to free up. If you're sure they are no longer useful to you, deleting them can help you regain some of that space.

You can uninstall unwanted apps manually and automatically. But to be honest, the manual way is time-consuming. We highly recommend that you use BuhoCleaner to do the job for you. Download the free version of BuhoCleaner to try it out now.

4. Delete DMG Files 

Once you have installed an application, its DMG files are useless. Since most apps don't remind you to delete their DMG files after installation, you’ll eventually wind up with a pile of DMG files that will rob you of the valuable disk.

Luckily, the process of deleting DMG files is quite simple. You can either delete them via Finder manually or download BuhoCleaner to save yourself a whole lot of time and effort.

6. Remove Duplicate Files

Deleting duplicate files is also an excellent way to reclaim space. Have you ever noticed how many duplicate files are on your Mac? There are far more of them than you may think. Many operations can create duplicate files, such as downloading the same file multiple times and accidentally copying some files.

If you are an experienced Mac user, you can find duplicate files manually, but this may take you a long time and require your patience and fortitude. But if you don't know much about Mac or you want to find an easier route, using a duplicate file finder tool to find and delete them is your best choice.

BuhoCleaner is the right tool for you. It can find and delete duplicate files on Mac, cloud drives, and external drives in minutes. The best part of this tool is that it also supports finding and deleting similar photos. It's worth a try.

7. Reduce Photo Library Size

The photo library is where all your photos are stored. If you're a photographer, you probably import a lot of photos to your Mac. That's why your photo library is huge. To avoid running out of Mac storage space, it's a good idea to delete unwanted photos from your photo library.

  1. Open the Photos app.
  2. In the Library album you will find all the photos. Select the unwanted ones, Control-click them, and select Delete X Photos.

  1. Open the Mail app.
  2. Go to the mailbox from which you want to delete messages. Select the messages you want to remove and delete them.
  3. Right-click on Junk, then select Erase Deleted Items and Erase Junk Mail.

9. Compress Files

Another way to free up Mac storage is to compress files that are infrequently used. There's no need to rely on third-party compression tools, as Apple has a built-in option that works just fine. Simply select the files to be compressed, right-click on them, and choose "Compress." The files will then be packaged into a Zip file, which can be stored on an external drive since they won't be needed frequently.

10. Empty Your Trash

So you drag those unwanted files into the Trash bin, but then you forget to clear out the trash? Overflowing trash bins can eat up lots of space. Go ahead and empty it! You will be surprised by how much space you'll get back.
