    I just got a 2017 iMac 27inch with the fusion drive. I am trying to turn on FileVault, but it keeps giving me the error "Boot file not written" Im not sure what to do and google hasn't been much help. I am on the latest macOS beta 10.13.3.

    And before anyone says "expect wonky stuff in betas" I know full well what comes with betas, however my MacBook Pro 2017 is also on the same beta and FileVault is fine, although it might be because it is SSD only, I'm not sure.

    Have you tried installing the non-beta release and then see if FileVault works?
