sorry if you've heard all this before but I've just purchased my 1st iMac (after years of recording with cubase,pc).I,ve also just got Logic studio 8 (boxed with about 8 discs) as my iMac is brand new it runs lion and it soon became apparent to me that the 2 are not compatible and that i need to upgrade to logic 9.What i'd like to know is what exactally do I need for my upgrade? do i just download from apple? do I need the full Logic 9 programme are all my discs (audio content ,jam packs etc) redundant and can i even upgrade something that's not even on my computer. any info appreciated and sorry for the boring post.
