A really quick and easy question I hope someone can answer.

Does filevault need a power supply? My new MacBook will not finish decryption unless connected to a power supply.

Cheers.

PS: Tried a search but couldn't find an answer to my question.

Yes. You will get a notification asking you to connect to power supply due to the heavier load the encryption will place your system under.
 
Thanks, guys. Battery was >90%, but still got the message. Maybe as this is a new Mac? Not sure.

Either way, it seems to be progressing (with periodic pauses to estimate the remaining time). Seems like it wants the power source...
[doublepost=1480289526][/doublepost]I don't think my Mac will be satisfied until it is complete, as I keep getting a pop-up alert if I take the power out.

How big is your drive and how much data is it encrypting?
[doublepost=1480289706][/doublepost]"After your Mac starts up, encryption of your startup disk occurs in the background as you use your Mac. This takes time, and it happens only while your Mac is awake and plugged in to AC power. You can check progress in the FileVault section of Security & Privacy preferences. Any new files that you create are automatically encrypted as they're saved to your startup disk."

That's really great, thanks for finding that.

I did a clean install, and the hard drive has ~800GB free (/1TB).
