I've had this in my .profile for years:

  alias sleepsafe='sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25'
  alias sleepfast='sudo pmset -a hibernatemode 0'
  alias sleepdefault='sudo pmset -a hibernatemode 3'

Whenever I travel or need to leave my laptop, I always run `sleepsafe`, which will delete the key from memory and hibernate the computer when I close the lid. It has the added benefit of saving battery life.

Day-to-day, I use `sleepfast`, which is faster than the default hybrid sleep, because it doesn't spend time copying the contents of memory to disk.

I very rarely switch to `sleepdefault` which is the insecure and slower hybrid sleep.

This has been a known issue for years http://osxdaily.com/2013/07/06/maximize-filevault-security-d... https://nakedsecurity.sophos.com/2012/02/02/filevault-encryp...

It doesn't work for me on Sierra, I disabled powernap and it keeps asking for my account password. Also I set standbydelay and standby to 0.

Edit: After some time and some tries, idk why but it started working.

Commands that I used:

$ sudo pmset -a darkwakes 0

$ sudo pmset -a standby 0

$ sudo pmset -a standbydelay 0

Also check that powernap is disabled.

I prefer YoNTMA: https://github.com/iSECPartners/yontma-mac

If the laptop is disconnected from AC, it hibernates. It will switch to hibernate if power is removed while already sleeping. If I want to force a hibernate manually, I just pull the power before closing the lid.

Thanks for sharing these awesome shortcuts!

Are there any caveats that I should be aware of before just stealing this to use for myself?

You could read through http://training.apple.com/pdf/WP_FileVault2.pdf for some of the details, or `man pmset`. Use `pmset -g` at any time to see your current settings.

Just make sure you eject any removable disks before hibernating. And, sleepfast may drain your battery faster than the default hybrid sleep

OP said sleepfast increases his battery life. It sounds like you lose whatever is in memory though
