I have a MacBook Air. I am trying to install portable DVD DVSM-PC58U2VB. I went to Buffalo's website and downloaded the .zip file, unzipped it, but all of the resulting files are Windows. I get the message "You can't open the application "DriveNavi.exe" because Microsoft Windows applications are not supported on OS X" when I try to execute any of the .exe files. Please help. Buffalo tech support did not respond to my online request for help, but I don't want to have to return the drive.
