1. Check Apple ID Device List Consistency
Make sure your Mac Studio is still listed under your Apple ID:
- Go to appleid.apple.com and sign in.
- Check Devices — is your Studio Max listed?
- If it’s not: That might explain why Find My can’t locate it.
- If it is listed but says Find My: Off, there’s likely a sync issue between iCloud and the Mac’s local Find My daemon.
2. Reset Find My Daemon / Location Services Cache
Try resetting the underlying services via Terminal (macOS can sometimes bug out silently):
a. Reset locationd
Open Terminal, then run:
bash
CopyEdit
sudo launchctl kickstart -k system/com.apple.locationd
Then reboot your Mac.
b. Check TCC Database for Location/Find My Permissions
Sometimes corrupted permissions settings prevent Find My from working properly. You can reset the TCC (privacy database) for location services:
bash
CopyEdit
tccutil reset SystemPolicyLocationServices
Reboot again afterward. (Note: This will reset location permissions for all apps.)
3. Check Secure Boot & Activation Lock Status
Find My depends on Secure Boot and Activation Lock being active:
- Reboot into macOS Recovery (hold Power button while booting).
- Choose Startup Security Utility.
- Make sure Secure Boot is enabled.
- Confirm Activation Lock is enabled in iCloud (check via another device or appleid.apple.com).
4. Create a Temporary Admin User
To check if it’s an account-level issue:
- Create a new Admin user.
- Log into iCloud using your Apple ID.
- Enable Find My just for testing.
If the Studio Max appears in Find My from this user, your main user account may have a corruption in its iCloud daemon.
5. Check for Broken iCloud Daemons
Corrupted preference files may prevent Find My from syncing properly.
Navigate to:
javascript
CopyEdit
~/Library/Preferences/
Look for and delete (or move to Desktop) the following:
- com.apple.findmy.findmyd.plist
- com.apple.icloud.findmydeviced.plist
- com.apple.locationd.plist (if available)
Then reboot and re-enable Find My.
Still Nothing?
If none of the above works and appleid.apple.com still shows Find My: Off on your Mac, yet System Settings show it’s on — then yes, it’s likely a deeper iCloud system-level desync or macOS bug. A reinstall or upgrade (once macOS 15.6 or a patch is out) might be your best next move.
