I'm on Mac OS10.8.2 2.4ghz core i5 4gb ram and have had lots of freezes,crashes and weird behaviour with T4.
Mackie plugs have no GUI
Cursor and play unresponsive on random songs/edits
Rewire only works when I put Reason6.5 into 32bit and even then it hangs generally behaves naughty.
Lots of other crashes too many to list really so if anyone needs the logs let me know where i can send them..otherwise i'm really chuffed you guys got Tracktion back from Makie..I look forward to updates and bug fixes.
