Opening a BitLocker encrypted drive on macOS Catalina and previous versions are not difficult at all. The only requirement is to grant Full Disk Access permission to UUByte BitLocker app. However, the situation has changed dramatically since macOS Big Sur and Apple's Mac with M1/M2/M3/M4 chip. More security enhancements are improved, such as disabling System Extension by default. Hence, many BitLocker Reader apps failed to work on Big Sur or Apple Silicon Mac.

 

Don't worry! The latest version of UUByte BitLocker Geeker adds support for macOS Sequoia and Macs with Apple M4 chip. But, there are more additional steps that need to be done before decrypting a BitLocker drive with BitLocker Geeker. Below is the step-by-step guide. Make sure you follow the steps accurately.
