It is generally a good idea to use full-disk encryption, especially on a laptop. However, this becomes bothersome if you are trying to re-partition your disk, say, to make the system dual-boot. Here’s a quick process that I used on my MacBook Pro.
- Reboot and hold down Command-R to boot into the recovery image.
- Open the terminal and review your disk partitions:
diskutil cs list
- Find the one that says “Locked” and unlock it with your root password:
diskutil cs unlockVolume UUID -stdinpassphrase
- Now you can initiate the decryption process:
diskutil cs revert UUID -stdinpassphrase
- Check on the status of your partitions:
diskutil cs list
