My new Mac Studio has suddenly started to reboot itself after I shut her down. This happens 50% of the time now.
I shut down as normal. It powers down. My 2 external RAIDs power down shortly after and then I manual turn of power to another eternal drive. (This has been my routine for yers). Then in a few seconds my Mac Studio powers up all by itself and reboots. Iʻm presented with a report that I guess gets sent to Apple automatically.
I had similar issues with my Mac Mini, both where it would go to sleep when I didn’t wanted it to, and at other times starting up although having told it to go to sleep, and observed it doing so.
On the first issue, after ZERO help from Apple support and several calls later, I found that there in the settings was two different settings that contradicted one another. Guess that it is the same issue when it randomly boots itself up – can only suggest complete shut-down, and then switch off at the wall or pull the power lead out…
I discovered what was causing my Mac Studio to re-start itself after shut has been completed. I have 4 external Seagate storage drives connected. If I take any of these offline (storage drives donʻt need to be spinning all day when they arenʻt being accessed) and shut down, the Mac Studio will reboot itself and give me a notice about a shut down issue. If I leave them running, no problem. The Mac will shut down.
So, is there a way to tell Mac if I take any external drive offline to shut down when I ask it to?
It sounds crazy that a Mac Studio that has been powered down, powers up to tell you what you already know. Not least as my normal sequence, would always be to shut down the computer first to keep the integrity of the any database/software accessing those external drives. And, then power off the drives. Times might have moved on, but surely there can be no good reason for a Mac Studio to, on its own, power itself up? I would look in settings, maybe even the drive settings, to see if you can stop it from happening.
