Glad to be a member, just joined you. I've run the upgrade to Logic Audio 6, and it starts fine, and is authorized. I want to get the instrument apple instrument plugs into the Logic 6/ OS X upgrade. They do not appear in the Audio Instruments track Inserts. I have the EXSP24/EVP/ES1 VST Plug ins in my Logic 5 OS 9 . ???? Do I have to move them manually to VST/AU plug in folder in my Library/Audio folder on OS X? ????? Do Ineed an Upgrade, and how do I go about it? ??? Or, is it an authorization problem? John Plum
