How Much Free Space Should I Have on My Mac?

Studies show that your Mac's performance starts to degrade when your storage space usage reaches 85%. To make sure your Mac runs properly, you need to have at least 10GB of free space. But we recommend that you keep at least 15% of your storage space so you can have more freedom to install new macOS, upgrade software, or download movies.

8 Best Ways to Free up Space on Mac

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

1. Optimize Mac Storage

The easiest way to free up disk space is to use the built-in optimization tools on Mac. You can easily find them by clicking the Manage button above the storage bar. As you can see from the picture, there are four recommended optimization options. Just follow the recommendations to optimize your storage space.

Optimize Storage

Store in iCloud: This feature allows you to store your photos, movies, and files in iCloud. So just keep the necessary files on your Mac.

Optimize Storage: Click the Optimize button to turn on this function, and your Mac will automatically remove the movies and TV shows you have watched to the Trash if storage is needed.

Empty Trash Automatically: Once you turn it on, the items that have been in the Trash for over 30 days will be removed automatically. 

Reduce Clutter: By clicking the Review Files button, you can sort all the files on your Mac and delete the ones you no longer need.

2. Clear Junk Files on Mac

 To quickly clear all junk files on your Mac, you need a third-party claner. BuhoCleaner is the tool for you. It's one of the best Mac cleaners, and it can help you clean and speed up your Mac with a few clicks. Some of its noticeable features are junk file cleaning, unwanted app removal, duplicate and large file cleanup, and memory release.

3. Uninstall Apps You Don't Use

You probably have many programs installed on your Mac. Is there an application that you have only used once? Unused applications are taking up your space for nothing. If you're sure they are no longer useful to you, deleting them can also help you regain some space.

You can uninstall unwanted apps manually and automatically. But to be honest, the manual way is time-consuming. We more recommend that you use BuhoCleaner to do the job for you. Click here to download the free version of BuhoCleaner.

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 in time, they will take up more and more of your disk space if you don't clean them up manually. The process of deleting DMG files is simple. You can either delete them via Finder manually or download BuhoCleaner to save time and effort.

5. Clear Temporary Files

Your hard drive probably has temporary files you don't need. Removing them may not speed up your Mac, but it will free up some valuable disk space for you.

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 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 requires you to be patient enough. But if you don't know much about Mac, using a duplicate file finder tool to find and delete them is your best choice.

7. Compress Files

Another way to clear Mac space is to compress files that you don't use often. You don't need to use a third-party compression tool because Apple's built-in compression tool is helpful. All you need to do is select the files to be compressed, right-click them, and select Compress, and your files will be packaged into a Zip file. Since you don't use these files often, you can store the Zip file on an external drive.

8. Empty Trash

In most cases, you may just drag unwanted files into the Trash but do not clear the Trash regularly. Why not take a second to empty it? If you do so, you will be surprised by how much space you'll save.
