Accessing 10.8 encrypted drive in 10.6
I have just recently done a clean install of Mac OS X 10.6.3, removing the OS previously on my MacBook, which was Mac OS X 10.8.2.
Before I did so, I ran a backup to my External HDD, however I have discovered that the HDD was encrypted, and 10.6 won't even try to mount it.
Is there a way to access my external HDD to get my files, or do I have to use a computer running 10.8?
MacBook, OS X Mountain Lion (10.8.2), 2.26GHz C2D, 13" Screen, 4GB RAM
