FileVault stuck on "Encryption Paused"
After upgrading my MPB to Yosemite, I elected to turn on FileVault. In the Security & Privacy panel of System Preferences, the status shows "Encryption paused" and the text under the progress bar reads, "Connect power adapter to resume encryption." Trouble is, I am running from the power adapter!
I have rebooted and tried another power adapter. The battery icon in the menu bar correctly changes from battery to power adapter as I connect and disconnect. However, the encryption status never changes. I have left the machine running overnight with no change.
Any ideas?
