Users of encrypted macOS computers are strongly advised to change their network password only from their Mac while on the campus network.
- Please watch for the emailed warnings of approaching password expiration and change it ahead of the deadline.
- If the password is changed elsewhere (for example, via resetpassword.davidson.edu) the Mac must be restarted and logged into while connected to the campus network; then run "FileVault Password Resync" from Self Service.
The initiation of encryption will only take a few minutes. The rest will complete in the background while you work normally.
Mac encryption requirements
- macOS High Sierra 10.13 or higher, if the Mac has an SSD hard drive, or
- macOS Mojave 10.14, if the Mac has either a Fusion drive or a traditional spinning hard drive.
- If you are on an older OS version, the 10.13 installer is available in Self Service. 10.14 access is currently available by request.
- If the computer is a laptop, plug in to power.
- Close all open programs, as the process will require a logout.
- Open the Self Service app and choose "Encrypt with FileVault2".
- Don't see it? Double check the requirements above. If you need help, contact T&I so we can investigate further; include your computer's Davidson College property tag number.
- You will be prompted for your password, warned of impending logout, prompted for your password again, then logged out. The logout may take a little longer than normal as the encryption process starts.
- Once you see the login screen, you may log in again.
The initial encryption will now be happening in the background. On laptops, it happens only when the computer is plugged in to power (it pauses when on battery).
- You may check the status of encryption at System Preferences, Security & Privacy, FileVault.
- On the newest models, encryption may complete almost immediately.
- On older models, encryption may take a few hours if there is very little data saved, or several days for large drives with a lot of data.
When you reboot the computer, you will see a slightly different login screen that appears almost immediately after the computer is turned on - the computer cannot boot until you use your password to allow the hard drive to be read.
- As long as your Mac and network passwords are in sync, you will only be prompted for your password once at startup.
- If your password is changed from somewhere other than the Mac, your passwords will get out of sync. Remember your old password! Restart the computer while connected to the campus network, log in, then go to Self Service and run "FileVault Password Resync".
