How to Fix "Not Enough Space to Install macOS Monterey" Error

How Much Space Does macOS Monterey Need?

The macOS Monterey installer is about 12GB in size. But you'll still need some extra space to install it. According to Apple, if you're upgrading from macOS Sierra or higher, macOS Monterey requires 26GB of available storage to upgrade. And if you're upgrading from an earlier version, macOS Monterey requires up to 44GB of available storage.

How to Check the Available Storage Space on Mac

Now that you know the total amount of space needed to upgrade to macOS Monterey, the next thing you need to do is to check how much free disk space you have. Here are the steps:

Check Storage Space
  1. Click the Apple Menu > About This Mac > Storage.
  2. After the calculation process is complete, hover your mouse over each part of the storage bar. You can see which types of files occupy most of the storage space and see how much space is available.

If you have more than 44GB of free space, then congratulations, you can go ahead and upgrade to macOS Monterey right now. But what if you don't have enough space? How can you make enough room for the installation of macOS Monterey? Read on for some solutions.

  • Optimize Storage – Turn it on, and the macOS will automatically delete iTunes movies and TV shows that you have already watched.

3. Uninstall Apps You Don't Use

You probably have installed a great number of applications on your Mac. Some of them may no longer be of any use. Deleting them will help you claim back some valuable storage space.

But how do you usually uninstall an app? Did you know the application is STILL on your hard drive! To completely delete it, you still need to remove its related files and empty them to the Trash. Here’s what you need to do:

  1. Click the Go menu in Finder and choose Library.
  2. Find the files associated with the application and move them to the Trash.

5. Delete Time Machine Backups

Your Mac will keep a copy of your Time Machine Snapshots in case your external drive can't be accessed. However, having them there will take up some of your valuable storage space. If you are absolutely sure that they are no longer needed, delete them from your Mac to reclaim space.

Here are the steps:

  1. Open Terminal via Spotlight or Launchpad.

  2. In the Terminal, type and run the command: tmutil listlocalsnapshots. (You should be able to see a list of backups sorted by date.)

    Find Time Machine Snapshots
  3. Type the command: tmutil deletelocalsnapshots "xxxxxxx" , enter the administrator password if asked, and hit the Return button on the keyboard. ("xxxxxxx" stands for the backup date of your Time Machine.)

  4. Repeat step 3 if you want to remove more than one Time Machine snapshot.

6. Remove Old iOS Backups

Those old iOS backups are no longer of any use. Deleting them will help you reclaim some space.

Here's how to remove them from your Mac:

  1. Open Finder.
  2. Click your device in the sidebar.
  3. Under the General tab, click the Manage Backups button to see the backups on your Mac.
  4. Right-click on the backup that you don't want and select Delete or Archive.
  5. Click Delete Backup, then confirm your deletion.
