Mac Does Not Show in Find My — Resolved via Safe Mode / First Aid
Symptom:
A MacBook Pro (M1, Apple Silicon) stopped appearing under “My Devices” in the Find My app, despite being my own Mac, signed into my own Apple Account, with Find My Mac enabled. Instead, it appeared under a family member’s device list in Find My and Family Sharing, with live location reporting — even though she had never owned or used the machine.
Root cause:
The device’s Find My Mac registration had become erroneously associated with a family member’s Apple ID rather than my own, likely from an early setup step. System Settings → Apple Account → Devices correctly listed the Mac under my own account, but the Find My app’s device-ownership record (a separate registration from general account device listing) still pointed to hers. This mismatch meant:
- The device could not be removed from her Find My list remotely (Apple only allows remote removal of offline/signed-out devices; an actively-reporting device must be released locally).
- Attempting to turn off Find My Mac on the device itself prompted for her Apple Account password, not mine, confirming the registration was tied to her account.
Steps that did NOT resolve it:
- Toggling Find My Mac off and on, repeatedly, on the affected Mac
- Toggling Location Services off and on
- Restarting normally
- Booting into Safe Mode alone
- Disabling third-party VPN and security software (ExpressVPN, Webroot SecureAnywhere) — worth ruling out, but not the fix in this case
- Having the family member attempt “Remove This Device” from her own iPhone’s Find My app (greyed out, since the device was actively online)
What finally worked, in order:
- Family member changed her Apple Account password. This, combined with re-authenticating, allowed her to successfully remove the Mac from her own Find My device list — something that had been failing before the password change.
- Even after removal from her account, the Mac still did not appear under my own “My Devices” in Find My. Turning Find My Mac off/on again made no difference at this point.
- The actual fix: Boot into Safe Mode → open Disk Utility → run First Aid on Macintosh HD and all subvolumes(including the Data volume) → reboot normally.
After the First Aid pass completed and the Mac rebooted, Find My Mac was turned back on under my own Apple Account, and the device correctly appeared under “My Devices” within a few minutes.
Takeaway for others with this problem:
If a Mac is stuck in a broken Find My registration state — especially one involving a stale or cross-account ownership record — and all the usual account-level and toggle-level fixes fail, don’t overlook a disk-level integrity check. Corrupted or inconsistent volume state can apparently interfere with how Find My’s local device registration reconciles with iCloud, even though nothing about the symptoms points at the disk as the cause. Safe Mode → Disk Utility → First Aid on the full volume set (including subvolumes) is worth trying before concluding the problem is unsolvable.
This took roughly three support calls, an Apple Support supervisor, and about 2.5 hours total to resolve. Posting here so the next person doesn’t have to spend the same time rediscovering it.
