Do you mean to ask what the battery management functionality is like (i.e. does the battery drain noticeably faster using OpenBSD)?
If so, I don't know what it's like on the MacBook or MacBook Pro, but on my Mac Mini, I can reliably say that the battery life is dismal ;-)
> but on my Mac Mini, the battery life is dismal.
Possible typo? The Mac Mini does not have a battery.
That's why the battery life is so dismal.
No, no, that’s why the battery life is amazing!!!
It always does what I expect when I unplug it...
That mac /is/ going to run off the power stored in the PSU capacitors for a few (hundred?) ms after you unplug it.
Not sure on OpenBSD, but Asahi said they could get 6-8 hours without any real energy efficiency features enabled.
Is Red Shirt Jeff going to install it anytime soon?
That sounds like significantly lower number of hours than a MacOS..?
Key part is without any energy saving features. Once those are implemented it will improve. I am pretty sure MacOS has a number of energy saving features implemented.
