I just mad the move from my old Windows laptop to my first iMac. My external drive was NTFS formatted and I could only read from it on my iMac but not write to it. So after backing up all my files I reformatted the hard drive to exFat. My computer will ask if I want to open the hard drive in OSX or Windows virtualization. No matter what I pick nothing happens. The hard drive icon does not show up. I'm unable to find any way into the hard drive. Any suggestions on what to do next? Thanks in advance!
