Upon leaving my old job, I was given my old Mac which I've used for years and got attached to it, I realised it has an institutional recovery key but I'd like to change that to a personal recovery key so I can easily store somewhere safe. Is this an easy process?
I found the answer by opening up Terminal and using the FDESetup tool, I run
sudo fdesetup changerecovery -personal -keychain and it worked.
Terminal prompted for password to unlock the disk but worked
