Can anybody recommend which is the best software to use, or if there is a free one that will let me free open BitLocker encrypted drive and copy files to the Mac.īitLocker Drive Encryption is a full disk encryption software developed by Microsoft for Windows operating system. I've had to use BitLocker on an external hard drive and I want to copy the files form the external hard drive onto my MacBook Pro, I've had a look at some of the programs online, most of which you've got to pay for.
