After a bit of help!! I have a 2022 Mac Studio M1 Max. It has started not booting up. When I press the power button the white light flashes on for about a second,the fans kick in and then it shuts down. Very occasionally it will load all the way through and when it does the studio runs fine and works perfectly. I have taken it to an Apple Genius Bar and they got it to boot and factory reset it but when I got it home it loaded up once and is now doing g the same thing. Has anyone else come up against this and how did you fix it please?
