I'm Gary's beta tester for Macs, and the first thing I did with the ARIA engine is test it on Leopard. It passed with flying colors. I had one issue, but it was GarageBand oriented, and Plogue is working on a fix for the next version. What they sent me worked fantastic.
The next real question will be... will it work on Snow Leopard?
DigiDesign was held up since the Leopard release because of a couple of bugs in the audio layer. The last patch (10.5.3) corrected the problems. Digi didn't specify what was causing their audio engine to burp.
Has anyone had any issues running logic pro or kontakt 3 in leopard? Just want to know if there have been little issues or compatability problems which while may not stop production altogether, do require work-arounds...something i dont have time for!
