Mac OS X, issues fixed in 10.2.3, 10.4.9: Style-linking in carbon/native applications: The native OpenType OTF support in Mac OS X did not initially include support for style links between OTF fonts. This means that OS X native or carbon applications which relied on the OS to provide style linking information will treat the fonts as having no style links. Therefore bold and italic style buttons will either not work or will create synthesized styles (smeared or slanted) instead of accessing the correct font. This can have side effects: opening or importing a document authored on an earlier OS with OpenType OTF fonts using style links may result in the correct font not being found. Workaround: For applications using Adobe's common font engine, such as InDesign, Photoshop, and Illustrator, one can work around this problem by putting the fonts in the application's fonts folder or in the application support:Adobe:Fonts folder. This issue was fixed in Mac OS X 10.2.3 to 10.3.9, reappeared in 10.4.0 and is again fixed in 10.4.9. Mac OS X 10.2.2 supports style links, but they may yield incorrect/unexpected results.
Cross-platform PowerPoint compatibility. Most of the incompatibilities between the Windows and Mac versions of PowerPoint emanate from the way the program is built inside the operating system (OS). Particularly from Adobe's Pro font collection, will show without problems in both PowerPoint for Windows and PowerPoint for Mac.
