Mac Can’t Recognize My BitLocker-Encrypted Disk, What Should I Do?

MacBook laptops and their operating systems do not directly support BitLocker-encrypted disks. This causes a drive access restriction whenever you want to access the important files you want to access on this disk.

Accessing your important data on this encrypted disk quickly becomes a hassle you will prefer not to deal with. However, there is a solution to this access problem with M3 BitLocker Loader for Mac software.

What to Do When Mac Does Not Recognize BitLocker-Encrypted Drive

One of the main reasons why you might be experiencing this block might be due to a recent macOS security feature. For macOS Catalina and above, the security feature requires full access to a drive before you can gain access to it. This is the reason why you need to use third-party software to access it for full disk access.

Below are two recommendations on how to make your Mac recognize your BitLocker-encrypted drive. These recommendations are:

  1. M3 BitLocker Loader for Mac software

  1. Formatting option on Mac

In a situation where you do not have any data on the BitLocker-encrypted drive, or you have already backed the drive up, formatting this drive on your Mac can help to decrypt it for your use. Formatting a drive helps you get rid of the BitLocker protection that is in place. It also makes it usable on your Mac when you reconfigure the format to a macOS-recognized format. If this scenario fits a situation you are in, follow the following steps to format your drive:

  1. Navigate to Disk Utility and select the drive with the BitLocker encryption. You should see this option under ‘External’ on the left sidebar.
  2. On the top menu, select ‘Erase’ to begin the formatting process. a small dialog box should appear asking for the format type and some other information. Select the format type you desire and select Erase to continue.
  3. On completion of the formatting process, navigate to your Mac home screen and access the drive directly without any restriction.
