pejacoby<p>OMFG do NOT lose control of the account that your macOS machine has Activation Lock tied to.</p><p>Kid’s 2016 MacBook Pro had some unrepairable disk errors and recurrent crashing. Went to Recovery Mode which accepted his _current_ AppleID to login to reformat the drive and recover from a backup. </p><p>But of course the Backup has the original Activation Lock and account. So for whatever reason it absolutely would not make it all the way through a boot up after a full restore.</p><p>Tried that a couple different ways and likely full borked the on-disk OS. Somehow got a 171GB “Update” partition that wouldn’t go away.</p><p>Along the way managed to get the machine removed from Find My in the current Apple account. </p><p>Then back to recovery mode, full erase and repartition disk. Recover over internet, install Sequoia from zero, and now using Migration Assistant from backup to bring everything back together.</p><p>Fingers crossed that by morning it’s all happy again.</p><p>I’m sure I fucked up somewhere early in the process…quite the adventure. At least we know someone who steals the machine would be S.O.L….</p><p><a href="https://infosec.exchange/tags/macOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>macOS</span></a> <a href="https://infosec.exchange/tags/recoveryMode" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>recoveryMode</span></a> <a href="https://infosec.exchange/tags/verificationLock" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>verificationLock</span></a> <a href="https://infosec.exchange/tags/restore" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>restore</span></a></p>
