csrutil disable
Restart computer
In the terminal, type
sudo open /Applications/TextEdit.app /System/Library/LaunchDaemons/com.apple.ManagedClient.enroll.plist
change
<key>com.apple.ManagedClient.enroll</key>
<true/>
to
<key>com.apple.ManagedClient.enroll</key>
<false/>
So that the changes take effect
For all those people telling wrong facts:
I updated to 14.2.1 for about 1h and got the MDM Registration menu point in settings and I realized it reseted my "hack". So reboot > csrutil disable > reboot >deleting the configs folder > creating Settings and the 2 files in it > reboot > csrutil enable > no MDM anymore
.. I mean until next big update.So @Signore74 stop talking bullshit.
