Sudden MBP shutdown

[Rod]

Thanks Jake, that’s a real help. I’m down the coast today, recharging my batteries. I’ll finish setup in two days.

I hope it was a one off too. I have downloaded and equiped Amphetamine Enhancer for my version of the app. I usually close my lid at night and anytime I'm going to be away from the MBP for an extended time because this is an open area and we have 3 cats. From what I read it seemed that for Drive Alive it was safer to have the Enhancer as it's not Sandboxed like the app and avoids issues with not allowing System Sleep when the lid is closed. So my settings are a little different to yours.
I see there is a class action under way against Apple for screens cracking and black bars and dead areas appearing on the M1 laptops. So until that's sorted I wont be getting a replacement. Probably when we return to Australia some time early next year.
