Ask HN: How to Hibernate Mac Studio?

3 pointsxeonax8 comments

Windows has feature where it pauses all running apps, and shuts down the computer. You can remove power, and then when connected back, it resumes wherever it left of. Even maintaining clipboard content, you can even resume unsaved games.

Closest I found in MacOS is reopen previous windows, which just launches the launcher of few apps I use, but doesn't actually resume.

What are you trying to accomplish by hibernating exactly?

While I'd recommend against it, the command I believe you're looking for is:

  sudo pmset -a hibernatemode 3

Edit: this does not appear to work correctly on macOS 15? I'm getting mixed results[1]. It looks like Hibernate was added back to Apple Silicon Macs with macOS 11.3[2]

I use softwares, that opens projects, which take some time to open, say for e.g. Unity Editor, Visual Studio etc. With the reopen windows thing, it just launches the Unity Hub, and Visual Studio Launcher. It doesn't actually open the apps to the state I was expecting, hence wasting time. I was looking for Windows like Hibernate, coz I don't need to keep it powered. Imagine, being able to resume from exact previous state, all undo history maintained, clipboard state, everything as was left previously, This is how it worked on windows.

If that's all you want, you can just put it on standard sleep. The power draw is minimal and since you have a desktop anyway, there's no battery drain concerns.

It will recover the state in a second or two this way.

Hibernate is useful if you like to keep a laptop unused for several days at a time, but in your case, it wouldn't really offer anything over regular sleep mode. The power cost savings would be a few dollars a year, at most.

Its disconnected from power during the day when I am not at home. So can't put it to sleep.

Hmm. Does hibernate mode 25 do the trick? https://apple.stackexchange.com/a/419577

It's not an option exposed to users, normally.

You have to set some CLI flags for it: https://apple.stackexchange.com/questions/51725/do-macbooks-...

Hmm, this doesn't seem to work right on macOS 15?

Oh yikes, my bad, it's way outdated. Sorry!
