I have a Macbook Air from 2020, with the Intel i5 processor, and it randomly shuts down, only to switch on again if it's recharging. I run a command on the terminal to see the cause and it reads:
previous shutdown cause: 8
and the Timestamp reads:
1970-01-0101:00:25.103274+0100
I've seen other codes, but 8 doesn't seem to show very often... Any clues on why this happens would be greatly appreciated.
Most of the shutdowns are code 5, so it was shutdown normally- either something on your Mac is scheduling shutdowns, or something else.
I would try resetting the NVRAM or PRAM on your Mac, then the SMC
Reset NVRAM or PRAM on your Mac - Apple Support
How to reset the SMC of your Mac - Apple Support
If the issue doesn't resolve itself, you may need to contact Apple Support - Contact - Official Apple Support
Good luck!
Interesting- I've never heard of shutdown code 8, but for the other codes, I would refer to this handy reference- macOS Previous Shutdown Causes
Thanks.
