maximum memory under Tiger: 16GB

Under OS 10.3, no application can utilize more than 4GB RAM. Apparently, Tiger raises processing from 32-bit to 64-bit, which makes it possible for "64-bit applications" to access quadruple the memory they could access under 32-bit processing.

Does anyone out there know whether Logic 7.1.1 can take advantage of this new Tiger feature, or are we stuck with a 4GB RAM ceiling until the application is brought up to speed with the OS?

logic so far is 32-bit

so if using logic only, stay under 4GB and save money, or if you want more power then Node another mac if you have one

soon we have 64-bit logic, not sure when but apple is full of surprises

Actually, the max memory of Tiger is far greater than 16GB (that's the maximum of the latest G5's, I believe).

However, until the Cocoa and Carbon frameworks are updated to 64-bit, all GUI-based apps will be 32-bit. Child processes & daemons, however, can be done in 64-bit. This will probably take some serious reworking in Logic to do so (and as Stash said, who knows what the development labs at Apple are up to these days).
