I used to DJ on a MBP, but download and arrange my music and crates on a Windows Machine. The hard drives I used were formatted as NTFS drives on both. A Mac can read NTFS formatted drive, but can't write to it. So any cue points or changes I make while DJ'n on the MBP are not saved. So I made my Window Machine a Hackintosh so I can read and save to Mac OS EXT (Journaled). So now I will change both drives to Mac OS Ext (Journaled), but I need a Mac Program that can sync both ways. So if I add music to one and cue points to the other, they can see each other and update the appropriate files on <b>both drives<b>. I used to use a windows program call ViceVersa Pro to sync both ways. I need a Mac programs that does the same. I looked at SuperDuper but it seems that it does not do two way syncing, just one way.
