I have a newly restored system on OS X 10.11.4. File Vault 2 is enabled, but when I put my computer to sleep and wake it up within 5 minutes of sleep it is going straight to my desktop without asking for my password which is unacceptable. Has anyone else experienced this? --- Post Merged, Mar 22, 2016 --- I toggled the setting again and restarted my computer and it is working properly now. This is a warning to people who updated that they may want to check to make sure it really is requesting your password immediately. I suppose this is a bug?
