macOS Sierra requires FileVault
Hello, my HD crashed today because of FileVault disk encryption, therefore The Apple Guy paused it and reinstalled my HD to Mac 10.10. Unfortunately I need to upgrade my MacBook to Sierra 10.12, otherwise I cannot install apps which I need to use for work (for example Sketch software). It looks like Sierra needs FileVault. Any suggestions on what should I do in this case?
