How to free up disk space on Mac

Macs and MacBooks are notorious for running out of storage space pretty quickly, and Apple has been trying to solve this issue, which the majority of its users are complaining about. In 2022 Apple released Mac and MacBook Pro models with large 8 TB hard drives and updated macOS Ventura to become more browser-oriented, performing most of the work online to reduce the toll on the hard drive.

Since these changes weren't made to all Apple machines on the market, but rather to a select group of top-priced devices, users are still turning to online forums asking “how do I free up disk space on my Mac?” And there are quite a few effective methods to get a Mac clean disk!

How to check how much free space you have?

A Mac’s operating system lives on its hard drive, and if the drive gets too full you’ll notice your device performing much slower. To prevent this from happening, keep an eye on how much free space you have on your Mac. Here’s how: 

1. Click on the Apple icon
2. Go to System Settings ➙ General
3. Click the Storage tab and select All Volumes

Here you’ll see a colored graph showing how your Mac’s storage is being used, with light gray representing free space. Move the pointer over any other color to see the amount of space each category uses (Documents, Apps, Photos, or System Data).

It’s always good to be aware of the disk space situation on your Mac to keep it under control, and there’s a more convenient way to monitor it — try iStat Menus.

iStat Menus is a system data collector that lives in your menu bar and provides vital information about the key performance indicators. All info on your memory load lives behind one clean blue bar you can access with a single click! If you choose to expand it, you can check the exact division of memory resources and load between wires.

Being one of the most comprehensive Mac monitors to date, iStat Menus lets you automate the process of controlling how much Mac clean disk space any app is using, plus it presents you macOS performance data in a clean format, so you’re fully aware of the situation within your Mac.

How much free space does my Mac need to have?

It’s a less-known fact that a Mac converts the available space on its startup disk into virtual memory used for daily operations. That’s why it’s recommended to keep at least 10% of the disk space free on your Mac to avoid the device slowing down its performance.

How to clear space on Mac

With an abundance of theories online, we’ve gathered a list of tried-and-tested tips for how to free up space on Mac, both manually and automatically.

Optimize your Mac storage

Before doing a deep dive into all possible options to help you free up space on Mac, try using one of your device’s built-in tools to optimize available storage space.

While you’re still in the Storage tab of your Mac’s System Settings, scroll down past the graph that breaks down disk space usage and you’ll see a list of actions Apple recommends you take to keep a Mac clean disk. From here, decide which suggestions you want to try and follow the instructions.

Move files to the cloud

One of Apple’s suggestions for how to free up disk space on Mac is to store more files in a cloud storage service. Simply choose the Store in iCloud option from the Storage tab in System Settings and your Mac’s Desktop and Documents folders, as well as photos and messages will be moved to Apple’s iCloud. Now this content will be downloaded to your Mac only when you try to access it.

The only caveat to this method is that iCloud only offers 5 GB of storage space for free and if you have a lot or very large files, that might not be enough to store them all. Whether you choose to buy more storage, or use other cloud services as additional storage space, it’s a good idea to connect those reserves to your Mac’s Finder using CloudMounter.

CloudMounter is a utility to help free up space on Mac and easily access cloud storages right from your desktop. Connecting your online storage accounts like Google Drive, Dropbox, and others to your Mac’s Finder, CloudMounter presents you with near unlimited storage capacity along with the flexibility of a built-in hard drive operation.

Use CloudMounter’s Connections menu to choose which drive you want to mount the most popular clouds as disks. Simply click on the drive you want to mount, log in, review the information, click Mount again and forever stop wondering “how do I free up disk space on my Mac?”

Remove temporary files

A Mac’s operating system depends on creating temporary files to perform correctly. When that data has played its part in helping your Mac’s smooth day-to-day performance, it becomes latent on your device and can take up a lot of space.

Here’s how to clear storage on Mac by deleting temporary files:

1. Go to Finder ➙ Go ➙ Go to Folder
2. Type in ~/Library/Caches/ and hit Return
3. Drag and drop cache folders to the Trash

Be careful with what you’re deleting though, as there’s always the risk of removing the wrong folder. But if you'd rather not take that risk, let a professional cleaning app like CleanMyMac do the job for you.

Empty downloads and trash bin

This suggestion might sound too obvious, but the reality is that we often forget to deal with our Downloads and Trash folders, while those keep accumulating files that rob our Mac’s disk space.

Here’s how to clear storage on Mac by cleaning up your Downloads folder:

1. Go to Finder ➙ Downloads
2. Select the files you want to delete, right-click and choose Move to Trash

Now you can right click on the Trash icon and select Empty the Trash. You can also automate this process to have files stored in the Trash folder for more than 30 days get permanently deleted automatically. Here’s how:

1. Click on Finder in the menu bar
2. Go to Settings… ➙ Advanced
3. Check “Remove items from the Trash after 30 days”

Clean your desktop

While you might think that a messy desktop can only hamper your personal productivity, it actually has a negative impact on your Mac’s performance as well. All those screenshots, random downloads, and other miscellaneous files scattered all over your desktop can accumulate to hundreds of megabytes of wasted storage space on your Mac.

Check your screen, move or delete the files you no longer need, and if you want to maximize the effort, here’s how to clear disk space on Mac by getting rid of the largest files on your desktop:

1. Go to Finder ➙ Desktop
2. Choose List under the View section
3. Sort your items by size and delete the largest files

It’s a good manual way to free up space on Mac, but there’s another way to organize and manage your desktop with the help of a file organizer, like Spotless.

Uninstall unused apps

The number of installed apps Mac users have on their device grew to 37 in 2022. Meanwhile, the average number of apps used daily is only 13 with 10 of those apps being pre-installed Mac apps.

If you’re wondering how to free up space on Mac, it’s time to evaluate your app situation and uninstall the ones you no longer need by dragging them to the Trash. Be mindful, however, that this action won’t remove any hidden files associated with the app, like logs and crash reports, for example. To remove those, you need to dig deeper into your Mac’s operating system, or simply use CleanMyMac’s Uninstaller module. Here’s how:

1. Launch the app
2. Click on Uninstaller under Applications
3. Scroll through the list of your unused apps and check mark the ones you want to remove completely
4. Click Uninstall

   

Clear browser cache

Any internet browser creates caches every time you visit a new page to load it faster when you visit it again. This improves your browsing experience, but as time passes, the pile of caches in your browser folder begins to weigh down on your Mac’s disk space.

Here’s how to clear storage on Mac by removing browser caches in Safari:

1. Open your browser and click on the Safari drop-down menu
2. Go to Settings ➙ Advanced

Delete junk mail and mail attachments

If your personal and professional life involves a lot of email correspondence and your Mac is running short on disk space, you should turn to your Mail app and remove unnecessary attachments and junk emails.

Every attachment you open stays on your Mac forever, robbing you of gigabytes of storage space. So here’s how to delete those attachments:

1. Open the Mail app and go to Preferences
2. Find “Remove unedited downloads” option in the General tab
3. Select “After Message is Deleted”

To delete junk mail, simply click on the Accounts tab within Mail’s Preferences, find the “Erase junk messages option” and set it to “After one month.”
