True Hibernate mode on MacBooks please

I know this has been in the spotlight a few times, but it would be really useful if Apple would implement a true Hibernate mode for MacBooks - I become increasingly frustrated when I'd would like to use Bootcamp and go into Windows on my 2019 MacBook Pro; but have to shut all my open items down in MacOS ...please could this be looked into - I am not the only one that has queried this. Many thanks

MacBook Pro 16″, macOS 15.1

Boot Camped Windows requires booting into Windows. Not possible to be booted into two operating systems at the same time.

Sounds like installing Windows using a virtual machine would be a better option for you if you want to remain booted in your MacOS at the same time.

Sure, thanks for the response, but for the record, a true hibernation mode reserves a swap file on the disk… so when you hibernate MacOS it dumps everything in memory to this file; which it then uses as it’s rebooting to have everything in exactly the same place, with all your Apps and Docs as they were (currently half the stuff you have open gets dumped, and only some Safari reload some tabs, if you’re lucky)!


…now hibernating, and then going into Bootcamp, would allow us to load up Windows (because you hold down the Option/Alt button as it’s booting which then picks the other partition) …when you’re done with Windows, if you power cycle and choose MacOS again, it’s simply going to read the hibernation file content and put it back as it was ……voila :-)


PS. having true hibernate also means that when the battery exhausts itself in that current deep sleep ‘25’ setting (which does happen after a day or two in my experience), it won’t matter because you can charge it up and still recover the system state to load exactly where you had it the other day…

Follow D.I. Johnson's advice above if you do not want to use a VM.

FWIW, I think the current boot into only one operating system at a time is the better approach.

And, non-Intel chip Macs do not support Boot Camp so don't expect updates to the old system.
