Hello, I finally took the plunge and loaded Snow Leopard, hoping to achieve a 64 bit Logic...hoping to utilize the 13 gigs of RAM I have installed. I understand there is a 4 gig limit with the 32 bit Logic and that the 64 bit will increase the limit to 24 gigs..... Unfortunately, Logic 9.14 says it is still in 32 bit. I thought it would automatically change to 64 bit when I opened Logic for the first time after the install. I did a search, but did not find the solution on the forum. Is there something I have to change in Logic to change to the 64 bit mode...I have been hitting the wall with memory issues in Logic.... Thanks, Bob

Hi Bob, Under Snow Leopard and with Logic 9.1.x you can run Logic in 32-bit or 64-bit mode. Because many 3rd party plugins haven't yet jumped on board the 64-bit train, by default, Logic is set to run in 32-bit mode. - Quit Logic. - Go to: Applications/ - Select Logic.app and hit Command-I (or File > Get Info) - Uncheck "Open in 32-bit mode". - Launch Logic and enjoy virtually unlimited ram! :)
