Encryption Explained. Data at rest is usually only encrypted if need be, but Apple encrypts the entire device when locked if it is iOS or iPadOS. macOS users can opt to encrypt their computers using FileVault, and those who own a Mac with a T2 chip will have encrypted drives automatically.
It is also dependent on the read/write speed of your disk. If you have a spindle hard drive (1TB) then it will take a lot longer than a 1TB SSD which have got much hight read/write speeds. When we encrypt 256 SSDs it takes about 1-2 hours.
How long does it take to encrypt? Initial installation of the full disk encryption software takes less than a half hour. After initial software installation, the computer will encrypt a spinning hard drive in an average of 8-10 hours and a solid state drive in 1-2 hours, depending on your computer's hard drive size.
FileVault is Apple's term for disk encryption. This makes FileVault a great choice if you handle sensitive information, or if you are concerned about the security of the data on your Mac if it's ever lost or stolen.
FileVault is easy to enable in System Preferences > Security & Privacy, and then once the intial encryption is over, it won't even slow your Mac down day to day. FileVault 2 takes advantage of the ever-improving processor speed and features in Macs to perform on-the-fly encryption and decryption.
To do that, follow these steps:
- Go to Utilities > Disk Utility.
- Check S.M.A.R.T status.
- Select your disk from the left pane and click on First Aid.
- Now click on Repair Disk or Verify Disk, and wait for the process to finish.
- If everything is in order, run the process again until you get two successful runs in a row.
FileVault is supported in Mac OS X 10.3 later, and it provides strong encryption for files and data on Mac computers, protecting the entire drive and all of the files located on the drive — just like BitLocker for Windows. Just like with BitLocker, you don't need an additional password to use your files.
When you turn File Sharing on in the Sharing pane, your Mac automatically adds the background service named “smbd†to the list of apps which have Full Disk Access. This ensures that it can share files in privacy– protected areas in Mojave.
To encrypt a drive, simply open the Finder and connect the drive to your Mac. Ctrl+click or right-click the drive in the Finder sidebar and select the Encrypt option. The disk will be encrypted once you enter your password of choice—be sure to use a secure one!

Reinstall your computer's original version of macOS (including available updates): Press and hold Shift-Option-Command-R. Reinstall the version of macOS stored on your computer's built-in recovery volume: Press and hold Command-R.
Data encryption slows performance and lowers productivity.Historically, data encryption did slow down less-powerful computer processors. "To many users, this seemed like an unacceptable trade-off to pay for the benefits of data security," according to the report.
The Apple T2 Security Chip is Apple's second-generation, custom silicon for Mac. The T2 chip delivers capabilities to your Mac, such as encrypted storage and secure boot capabilities, enhanced image signal processing and security for Touch ID data.
If you see the option to reset using your recovery key
- Click the option to reset using your recovery key, then enter your FileVault recovery key.
- Enter your new password information, then click Reset Password.

- Select "Disk Utility" and click "Continue".
- Select startup disk in left-hand sidebar and click "Mount".
- Enter recovery key in password field and click "Unlock".
How to Turn Off Encryption and Decrypt External Drives on Mac
- Connect the drive or volume you wish to decrypt to the Mac.
- Select the external drive (either from the hard drive or the Finder, or from the Devices menu in the Finder sidebar) and right-click on the drive icon, then choose “Decrypt 'DriveName'…†from the list.
Clean your keyboard. Dust and other debris represent the most common cause of malfunctioning MacBook keyboards, so start by cleaning it to the best of your ability. Here's Apple's recommended procedure: Hold your MacBook so the base is at a 75-degree angle with the floor or table.
Try clicking the lock where it says "click the lock to make changes" and it will ask for the password and then it will enable you to click on the "encryption paused" and it will resume.
