iMac 21.5-in. Late 2009 won’t boot properly.
Bought a Late 2009 iMac 21.5 inch that worked almost like new. Had a user account already so I went into recovery mode to reset the Mac the set it up brand new. It now only starts up into recovery mode and will not launch normally. The account had been empty, but I was unaware you could change the name of the user account until after I had this issue, or else that would have appeased me 😅. The Mac is running High Sierra.
