Instructions to set Up FileVault 2 on a Mac
Email template to guide clients into setting up FileVault 2 in their Mac
I’m writing to send instructions on how to set up FileVault 2 in your computer. Please follow these steps and let me know if you have any questions.
Create a recovery/backup of your data to avoid any risk of data loss:
Prepare an external hard drive to store the backup. To backup your files, you can us Time Machine or an OS X Server from your network.
You can find instructions on how to back up your files on an external hard drive with Time Machine here: https://support.apple.com/en-us/HT201250
You can find instructions on how to set up Time Capsule on a local network for the first time here: https://support.apple.com/en-us/HT201510
Please note that the first backup may take some time
Turn on FileVault by following these instructions: http://support.apple.com/en-us/HT4790
When configuring FileVault, you can choose between two options:
- Allow my iCloud to unlock my disk
- Create a recovery key and do not use my iCloud account
If you can keep your recovery key in a USB stick that you can keep in a safe place and not share with anyone else, the second option is safer.
Please keep in mind that full- disk encryption is only effective when the computer is powered off.
