I just picked up my new 13" rMBP and was in the process of setting it up. It is now frozen on the FileVault screen (the one where it asks if you want FileVault to be enable and to allow my iCloud account to unlock the disk). Is is expected to sit here longer than 15-20 min? That's how long it has been so far. I didn't request any files to be automatically transferred from Time Machine or another mac, so there should not be much data at all. Any help? I tried googling around and looks like there are FileVault bugs, but would that affect a new machine on first boot? Edit: Looks like it's finally progressing. Upon getting to the desktop screen I got a message saying "FileVault encryption paused, plug in power to continue." Do most people use FileVault? Will it affect runtime performance?
