I recently bought a new, second hand imac 27 i5 to replace my older imac 24. I bought Logic 8 a few years back so had it installed with serial on imac 24. It is also installed on a macbook. When I attempt to install Logic 8 on the new mac after entering the serial the next page, asking which parts to install, greys out logic pro part and other components. Why is this? I understand the limit of only using Logic 8 on two computers but I'd like to leave it on the old imac 24 to wrap up a few projects during the transition period. If need be I am happy to uninstall it from macbook for the transition period. However, both the imac 24 and macbook are both switched off when I try to install on the new imac 27 so how does it know...I thought the number of machines was worked out via the network? I am not trying to wangle more uses that is legal, I simply want: Logic 8 on new imac 27 and 24 and am happy to delete from macbook for time being if need be. What should I do and what order should I do things in? Any advice greatly appreciated...I really want to get going with the new imac!
