Does Mac hibernate? Because if it does, the wake up is literally under 100ms, it's just imperceptible. You open the lid and it's already awake.
- bzzzt 1y agoMac M series don't do hibernation, probably because sleep has so little impact on battery life (my MacBook lasts for about a month in sleep mode) and Apple doesn't like to burden users with questions like 'what sleep mode to use'.
- izacus 1y agoThat's just plainly not true. Apple calls it "Safe Sleep" (https://support.apple.com/en-gb/guide/mac-help/mh10328/mac https://support.apple.com/en-gb/guide/mac-help/mh10328/mac) and you get a progress bar when it wakes from it. Yes, even on magical Ms.
- bzzzt 1y agoInteresting, never heard of that specific mode before. Does it save the entire RAM or just the OS state and open files?
- saagarjha 1y agoIt's proper hibernation with all your RAM
- acchow 1y agoMost people don't encounter this. It only happens when your macbook battery is about to die while in sleep mode.
- didibus 1y agoAh yes, I think I've seen this before, it still resumes impressively fast from it, and I think since I normally notice the battery is almost dead it gives itself a good excuse.
- didibus 1y agoRight, that's what Linux laptop needs, not hybernation.
- acchow 1y ago> Does Mac hibernate? Not by default. If you just shut the lid on your macbook and put it in your backpack for 2 days, it does not hibernate. Which is why waking is instant.
- didibus 1y agoThat's what I thought, so I disagree with OP, we don't want hybernation for Linux, we simply need way better power management and hardware that can sustain low power drain for weeks.
