Hi folks, I just got myself a Macbook Pro (10.6) to replace this Macbook (10.5) and spent most of today copying my files across with the Migration Assistant and I'm beginning to think this might have been a mistake. I installed L9 from the DVDs (hours) then did the software update to get up to the latest version and tried to launch Logic. I'm now having problems validating AU plugins. If I open AU manager and select a plugin, I get a blank, grey panel opening. A google search implied this might be something to do with 64 v 32 bit mode and to open in 32 bit mode. The Apple site says to check the 'open in 32 bit mode' box under 'get info' for the Logic app. Well, get info panel does not appear to have such a checkbox. Sorry for the rambling attempt to explain my problem but any ideas or pointers would be greatly appreciated. Cheers, Robert.
