MacBook Pro shuts down during boot. Strange IssuesI am an experienced certified ACMT/ACPT tech since OS 7.5 but in a kind of semi retirement and looking now at fixing macs...
Ответ на "SMC Interrupts Boot Process: CAN Use Target Disk Mode, Fans HIGH"can you check where u get stuck on verbose mode? If your SMC turns Amber-Green-AMber, i think you are ok. Your boot drive seems to be ok. Your RAM seems to be OK. Your network ports seem to be ok (you did a diagnostic / recovery boot successfully). Your keyboard seems ok. Your connectivity ports seem ok. Some of these point to an SMC which is ok. Did you repair your logic board recently or interchanged parts? if so - it could be the DSMOS (Dont Steal Mac OS) that could be holding up your boot process. Or it could be a faulty graphics card. Take a hi res video during verbose booting and try to see which line your process is getting stuck. I have the similar problem (multiple) but my issue is a bad SMC.
