I've succeeded installing version 1.4 on my PowerBook, but it never worked on my G5 ! It gets stuck on searching the hard drive and never starts installing... Too bad as I have problems (with the precedent version and since Tiger) to get sound out of the 828mk2 when I wish to listen to anything coming from the Mac (iTunes, navigators, etc.) ; however sound comes out when I use Cubase !? Very strange... I hope MOTU gives a correct update soon.
