Adobe CS 6 to require 64-bit Mac
March 28th 2012
From CNET:
To make the most of these features, Adobe built them using 64-bit code optimized for multicore systems, which therefore means the suite will run best on a fully 64-bit native Intel and AMD systems...
The drum of progress beats on. While CS 6 will support 32-bit Windows system, at least in some capacity, Mac users will need to upgrade their legacy gear. This excludes Macs running with a Intel Core and Core Duo CPUs. You will need at least a Core 2 Duo Mac, which Apple introduced into its computers around 2006. Adobe said they're following Apple's lead in not supporting legacy hardware. OS X Lion, which shipped last summer, also required a 64-bit CPU.
