Thanks JWL for the great summary of the OS 64-bit issue. Yes, I read this article before you posted it and was the main reason why I was questioning why VSL didn't provide an application that would exceed the 4.0 GB limit with Leopard. The article states the same info that the Apple techs have been telling me all along. If a developer wanted to code in Cocoa Framework, they could have provided an application that allowed a user to exceed the 4.0 GB limit.
I purchased the MacPro versus purchase for the same money 4 PCs. I made that decision based on the fact that the CPU power (8-cores) would approximate having four individual PCs and that the processors being 64 bit would allow access to the same amount of memory. Where things fells short, is that the application wasn't written in such a way to work with the hardware and current OS.
The point I was trying to make is that Leopard has been released now for over a year and we, the Apple users still do not have a VI application that allows us to load samples beyond (for VI, 3.0 GB if your lucky and 2.5 GB for VE). The article clearly states that it was possible to do so.... "Apple's current implement allows the existing 32-bit kernel to run both 32-bit and 64-bit applications at once, as well as being ahble to HANDLE 64-bit VIRTUAL MEMORY ALLOCATIONS, giving 64-bit applications and background task the CAPACITY TO ALLOCATE MEMORY SPACES LARGER THAN 4GB when working with large data sets.
Bottom line, the capability was there - provided by Apple, the desire by the software developers was not....
What absolutely upsets me is that when I purchased the entire VSL library, the web site stated 64-bit coming soon. Now it says under development. Soon to me was 1-2 months back in 2007 not late 2009....
