I have a late 2013 Macbook Pro (
MacBookPro11,3) running OS 10.9.3 that I want to keep as locked down as possible since I have sensitive company data on it. To that end, I have turned on FileVault, set
DestroyFVKeyOnStandby 1 hibernatemode 25, and set a firmware password. I have turned off Wake for WiFi access, Power Nap, and graphics card switching.
This set up works most of the time. However, I have found that it always crashes under the following sequence:
- Sleep by closing the lid and then Hibernate while connected to power
- Remove power. The display backlight comes on; wait for it to go out.
Boom, no more waking, now I have to hit the power button to reboot the machine. (If I remove power but immediately open the lid, then fully wake the machine by entering the firmware password and then the FileValut password, I'm fine.)
Of course I'd like a solution that maintains the protection of the data while the computer is sleeping/hibernating, but I'd settle for theories about what the computer is trying and failing to do when power is removed while hibernating so that maybe I can figure out a solution from there.
