Are you trying to update to macOS 12 but you’re faced with the macOS Monterey not enough free space to install issue? This is a common problem experienced by MacBook owners with low amount of storage space. macOS 12.0.1 requires almost 40 GB of free space to deploy and install itself on a Mac!

macOS Monterey Not Installing

You’ve downloaded macOS 12.0.1 in System Preferences -> Software Update and are now trying to update.

However, you get the error saying “The target volume does not have enough free space to install”. macOS also informs about the additional free space required for the update to be installed, on the selected disk.

This happens after clicking the ‘install macOS Monterey’ file. You click Continue and are prompted to select the drive that you want to install macOS 12 on.

However, after selecting Macintosh HD the above info message is displayed, hovering on top of the disk’s thumbnail and the ‘Continue’ button is greyed out!

There are two ways you can create additional space for the macOS 12 update:

If you applied all the steps described above and the Macs available storage is still not enough, you can free up an additional 12.17 GB, by using an external disk for the installation process.

If you have an external drive that’s large enough, you can copy the install macOS Monterey file to the external drive and delete it from your MacBook. This will free up over 12 GB on your computer as you can create an alias and run the installation from the external disk.
