Has anyone noticed this, and if so, found a solution? I have FileVault 2 enabled. Recently, I noticed that when I reboot (such as after installing a Software Update that requires a reboot, or after Boot Camp), after I enter my password, the spinning circle comes up for about 15 seconds. The screen then goes blank, it chimes again, the login screen comes back up, and it starts normally after that. If I disable FileVault 2, it starts up normally, however FileVault 2 is supposed to coordinate the logins so you only need to enter it in once. I have an i7 11" MacBook Air, so am not sure if this is strictly a FileVault issue, or one with the interaction of FileVault with the MacBook Air. I have tried disabling and re-enabling FileVault, and also changing the password.
