Hi all Looking for advice here. I had Filevault (the earlier legacy one) enabled on my 2007 MBP. When i installed Lion and tried to move to Filevault 2 it was impossible because the space needed was bigger then my drive. I was therefore rather hesitant about about enabling Filevault 2 on my new MBA. What are people's experiences? Would I be better waiting until after Mountain Lion??? Advice please!
