Hey,

Does anybody know what the hibernation feature is for M1 Macs? - Saw it in the release notes for 11.3 but after installing can't actually see anything on the system that alludes to this feature at all...

It is the same as hibernation on intel macs. After the mac has been in sleep mode for a long enough time that the battery is running low, it transparently hibernates by writing state to disk and powering off.
 
I haven't installed 11.3 yet but I'm curious what pmset -g | grep hibernatemode returns. Currently on 11.2 it returns nothing.

M1 with 11.3 =

hibernatemode 3

hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from hibernate image.

So it’s automatic?
