You kept the Recovery Key: If you opted to write down the Recovery Key, the text will continue “…reset it using your Recovery Key.” Click the right-pointing arrow and then enter your Recovery Key, omitting hyphens–macOS adds the hyphens automatically.This will recover your key, unlock the drive, and let you reset your account password. iCloud escrow: If you chose to store your key in iCloud during FileVault setup, the sentence above continues, ellipsis and all, “…reset it using your Apple ID.” Click the right-pointing arrow and follow the steps provided to log into the iCloud account associated with this Mac.( Read our explanation about how T2 and M1 Macs interact with FileVault.) Intel Macs with a T2 Security Chip and on all M1 Apple silicon Macs always encrypt this data. For Intel Macs without a T2 Security Chip, FileVault also encrypts the contents of the startup volume’s data when the computer is powered down. Only after the login does macOS enter its normal operation mode. That’s a dangerous situation if someone has physical access to your computer–in your home or office or because they’ve stolen it–they might be able to employ known and not-yet-discovered methods to bypass the login and access the drive’s contents.įileVault on all Macs puts an additional bar in place: your startup volume (or, as in the case with macOS Catalina and later, the startup data volume) is encrypted and its files are unavailable unless and until there’s been a successful macOS login. With FileVault disabled, the data on that volume is effectively just one password away between an attacker and your files. FileVault hardens macOS by wrapping a layer of login protection around the part of the startup volume that holds your files and other data.
