Adobe this week has posted for download a 9.0.2 updater for Photoshop CS2 for Mac. Back in August, the company briefly made available 9.0.2 for Mac via the program's software update mechanism, but that update was found to have a printing bug that affected OS X 10.2.x and 10.3.x systems and was quickly pulled from circulation. This 9.0.2 updater has the same fixes as the earlier 9.0.2, plus a correction for the earlier 9.0.2's printing bug.
If you installed the earlier 9.0.2 updater for Mac, the new 9.0.2 updater's Read Me document notes that Photoshop CS2 must be reinstalled before running the new updater.
The 9.0.2 updater for Windows versions of Photoshop CS2 was released on August 23, 2006; it has not been re-released as it was not affected by the same printing problem as the Mac version of 9.0.2.
