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.
