Upgrading a Mac to macOS Big Sur without enough space can result in data loss
Upgrading a Mac to macOS Big Sur without enough space can result in data loss
After noticing several reports from users on the web, Mr. Macintoshfound out that the macOS Big Sur installer isn’t checking whether the Mac’s internal storage has enough free space. As the system initiates the update process, the Mac becomes unresponsive, and data can be permanently corrupted.
Apple says upgrading to macOS Big Sur for the first time requires at least 35.5 GB of available storage — and this doesn’t include the 13 GB macOS Big Sur installer. Unfortunately, even if your Mac does not have 35.5 GB of storage available, macOS will try to install the Big Sur update, and that’s when users may lose all their data.
