I have an important user who accidentally did something to his MacBook Air, and I need to blow it away and start over. I do need to backup and restore his files, apps and settings. I am a Windows engineer, so I have a few questions.
(1) is Time Machine the best option for the backup, and if so, how long would an initial backup take (generally 1-2 hours?).
(2), if I use the Disk Options, does the OSX OS install automatically or do I need the OS software disk.
(3) Is there anything I am missing here?
