my brand new new macbook air M2 randomly reboots when i am not using it. sometimes 5 reboots during the night ( i know this because i get messages that i must eject my time machine before turning off computer ) am not a young computer savvy kid. i am an old lady and just want my new computer to work properly . a phone tech supervisor talked me through disk utility first aid stuff and installing a new ventura. but it did not work. anybody out there got the answer???
