Why would the developer curse apple in this situation? 64bit apps have been out for a very long time on the apple end. And what exactly did Apple screw up?
Adobe is the one that waited until cs5 to port to 64bit
From all reports I hear on LuLa, Apple has screwed up royally on color management recently. If I were a developer I might want to wait to see if Apple is going to change the rules for something else essential before committing much time to a project.
I am speculating wildly, of course. I have no information beyond what I read here. But it seems odd that between Microsoft and Apple, it is now Microsoft that is trying to look like the more reliable.
