FileVault and iCloud ID
I have a basic question, but can't seem to find the answer after searching for it. I have an iMac running El Capitan 10.11.5. I have FileVault enabled. My question is: Is it possible to use my iCloud/Apple ID to login to my iMac with FileVault enabled or do I have to have a local account (separate user/password) on my iMac?
When I go to Settings-Users and Groups, and click Change Password, I expected to see a dialog that would offer me to use my iCloud ID as the login for my iMac (shown below - as indicated in several articles I read). But it's just the standard dialog for changing the local password.
Any assistance would be appreciated. Thanks.
