[QUOTE="phoenixx, post: 1896410, member: 400439"] ok, I’ll try :) 1. there is no firmware password on it ? 2. boot to internet recovery - ideally via wired connection not wifi 3. format ssd first via disk utility to APFS ( GUID table ) 4. open terminal and verify you have proper date/time set ( via command “date” ) if not, enter date -u 1109212222 5. close terminal and try to instal Monterey if it fails, try to boot into safe mode - holding Shift key while booting - and try to install Monterey from the system via App Store. I had similar issue once, I tried different internet connection - I guess via cellular network - and it did the trick … let me know the results … [/QUOTE]
