As with any OS update, Mac OS X 10.5.5, released nearly two weeks ago, is a bit of a trade-off. While the update fixes a slew of bugs, it inevitably introduces a few new ones. In some cases, the bug is more the result of a third-party application having problems with the update, rather than the update itself. Here are two examples:
Adobe printing errors
According to an Adobe TechNote, after updating to Mac OS X 10.5.5, "printing to certain printers from Illustrator, InDesign or InCopy results in pages rendering with incorrect scaling and/or rotation." Based on reports in Adobe's forums, the most common specific symptom appears to be that, when printing to Adobe PDF 8.0, a resulting image is half its expected size.
Adobe offers three work-arounds. The simplest is to export the file as a PDF and print it from Acrobat or Adobe Reader. Otherwise, from your original Adobe application, select Print and navigate to the Printer Features options. From here, change the printing resolution back to 600 dpi. Unfortunately, this is not a permanent fix, as the settings change is not retained as a preset. A third solution, as detailed in the TechNote, is to use the "Defined by Driver" option in Paper Size control, also accessed via the Print dialog.
Adobe says it's "investigating" the issue. Expect a fix eventually.
Green-purple video display
Elgato reports that Mac OS X 10.5.5 introduces a rare problem, where video is displayed with a very annoying green-purple cast. It appears to be linked just to certain combinations of hardware (especially Power Mac G5s with ATI Radeon X1900 Graphics cards).
The proximate cause is the new version of OpenGL in 10.5.5. This means that, if you have the troublesome hardware, you'll see this symptom in Elgato's EyeTV, Apple's own DVD Player and any other application that uses OpenGL.
As a work-around, but just for EyeTV, you can turn off use of OpenGL. To do so, launch Terminal and type:
For other affected applications, you may have to wait for Mac OS X 10.5.6.
