Graphics, User Interfaces From John Nack's blog: "In the interest of giving customers guidance as early as possible, we have some news to share on this point: in addition to offering 32-bit-native versions for Mac OS X and 32-bit Windows, just as we do today, we plan to ship the next version of Photoshop as 64-bit-native for Windows 64-bit OSes only."

It's not that Adobe didn't have time or Apple didn't push them. It's that Adobe wanted to reap great rewards from poor and very old code.

When Adobe brought out Photoshop 7 around 2001, it was the first version that ran under the Carbon libraries, so that it could be a native Mac OS X application. It also ran much more slowly as if Adobe added the "include carbon.h" line in the source code and linked to the carbon libraries without doing anything more. Photoshop 6 in the Classic environment, with Mac OS 9.x as a host, ran faster.

The application became a progressively worse performer through CS and CS2, showing that it was never really re-written for Mac OS X but patched.

After a very long delay, the CS3 version finally works reasonably well, but doesn't remain completely idle--always taking around a minimum of 3% CPU--unusual for a Mac OS X application.

The on again/off again decision from Apple concerning 64-bit Carbon is a pain but Adobe knew what was ahead and they chose to do the cheap thing, again.
