Bugs found in Apple’s latest operating system, macOS Big Sur, seem to cause serious data loss for some users. The bug is included in “Big Sur 11.2” and affects data such as “Big Sur 11.3”. Mr. Macintosh explains the details in the video.
According to Mr. Macintosh, this bug is due to the macOS Big Sur installer not checking if the “Mac” has the free space needed to perform the upgrade. Problems occur when upgrading with insufficient free space. Even if the problem isn’t too serious, if the user’s Mac is encrypted with FileVault, the data will be inaccessible.
