CS-80V doesn't work on Leopard (a clean install) for me. It keeps on coming up with "No document could be created" errors and crashes Logic Pro whenever I select it. Not good.
If I go into Terminal and type "auval -v aumu Cs80 ArTu" to test the plugin, it tests the opening times on cold and warm starts, but quits out on the "first time" test.
It definitely has issues.
