Your hard drive is now 100% full and the installer is now stuck in a boot loop attempting to finish the install. The upgrade will start even if you only have 1% of free space left and will fail. You should see a pop up message showing you how much space is needed before you can attempt the upgrade again. Now you may wonder how much storage do I need on.
#MACOS BIG SUR NOT ENOUGH SPACE UPDATE#
If the installer finds that you do not have enough free space for the upgrade, it will stop and not let you continue. You may face problems like not enough space to update mac or mac says not enough disk space but there is. hmm i have well over 200gb of free space but keep getting 'Disk does not have enough free space to build 'Install macOS Big ' 'I see others have had this issue but i am providing full paths for the script and the chosen folder is writable. Once you’ve done so, you’ll be prevented from installing macOS Big Sur if you don’t have enough space. When you start the macOS Big Sur upgrade, the installer should first check to make sure your Mac has enough free space available. If you’re not using 11.2.1 (20D75), remove it and reinstall the macOS Big Sur update package. Those who found they didn't have enough space to complete an update are left with a Mac that refuses to boot.

However, it isn't going to help those who are already having issues. Macintosh, Apple has quietly released a new build of macOS Big Sur 11.2.1 (20D75) that prevents installations when insufficient space is available. Apple has released an update that should prevent users from being able to begin a macOS Big Sur installation even when their Mac doesn't have enough storage space.Īs reported by 9to5Mac and Mr.
