Time Machine is a built-in backup feature of macOS that allows users to automatically back up their entire system, including applications, system files, and personal data, to an external drive or network location. It enables users to restore their Mac to a previous state, such as before a problematic update, by selecting a specific backup point. In this scenario, Jack needs to revert his MacBook to the previous OS version due to issues with the beta update. Time Machine is the appropriate tool because it provides a user-friendly way to restore the system to a prior working state.

Option A (Time Shift):This is not a recognized feature in macOS. It seems to be a fictional or misnamed option.

Option B (Image Recovery):While image recovery refers to restoring a system from a disk image, it’s not a specific macOS feature and is less user-friendly than Time Machine for this purpose.

Option C (Snapshots):Snapshots are point-in-time copies of data, but in macOS, they are part of Time Machine’s local backup system and not a standalone feature Jack would directly use to restore his OS.

While EDRP focuses on enterprise disaster recovery, it covers backup and restoration tools like Time Machine under personal system recovery concepts, emphasizing the importance of regular backups for system restoration.
