Seems to not be working in Big Sur

[holmesworcester]

This seems to not be working in Big Sur.

Steps to reproduce:

1. Follow SMC/NVRAM reset steps in README
2. Run secure-hibernate.sh
3. Close laptop lid and wait a few seconds

Expected: laptop takes some time to become responsive again
Actual: login screen visible instantly, and account appears instantly.

It could be that the wake from hibernate is just happening really, really quickly, but that seems unlikely. Is there a way to verify that the key is removed from memory when the laptop is closed?

Thanks a lot for all your work putting this guide together, and for caring about an often-overlooked problem!

pmset -g log | egrep "\b(Sleep|Wake*|DarkWake|Start)\s{2,}"

If hibernating, a line like

2021-01-27 19:34:17 +0100 Sleep Entering Sleep state due to 'Clamshell Sleep': Using Batt (Charge:92%) 266 secs
2021-01-27 19:38:43 +0100 Wake Wake from Hibernate [CDNVA] : due to EC.LidOpen/Lid Open Using BATT (Charge:92%)

should be shown....

Instead of Hibernate, I see Wake from Deep Idle [CDNVA] : due to EC.KeyboardTouchpad/UserActivity Assertion Using BATT (Charge:77%) with a MBP 2019 and Big Sur

Same 'problem' as @holmesworcester - Wake is instant and can use TouchID upon wake
I have removed destroyfvkeyonstandby as it causes Kernel Panics and is not needed for Macs with a T2 chip
