Actually, Adobe has posted a very long, detailed list of problems between its software and Lion. Here's a snapshot of some of the most notable quirks:
- Java Runtime needs to be installed manually, otherwise applications may behave inconsistently.
- Rosetta support is no longer included with Lion.
- Adobe Reader plug-in and Acrobat plug-in are not compatible with the Safari 5.1 browser.
- Scrolling behaviour opposite of expected.
- Flash Player: may cause higher CPU activity when playing a YouTube video; settings dialog does not respond to mouse clicks.
- Illustrator CS5, Illustrator CS5.1, InDesign CS5.5: Crash reporter doesn't appear, or only appears after long delays.
- Dreamweaver CS4: Color Picker returns incorrect sample colour.
- Photoshop CS3, CS4, CS5: Droplets don't work.
- Premiere Pro CS5: Universal Counting Leader is missing countdown numbers.
One also has to ask: Why weren't these problems foreseen and/or addressed before Lion was released? After all, we've known that Lion was coming for months. It's not like this new version of Mac OS X was just rushed out.
The answer could be found in Apple and Adobe's tumultuous history. The most significant roadblock in the past between these two foes had to deal with Adobe's Flash technology. Basically, Apple's iPhone and iPad don't support Flash in favour of HTML5 (although there are some tricks and apps for getting around this). Apple CEO Steve Jobs has made it clear that he doesn't care, and that the company has no intention of working to reverse this.
Now, although not having Flash support on the iPhone and iPad can be annoying sometimes, it is possible to live without it.
However, for desktop browsers, Flash support is absolutely essential as so many websites still use this technology for video streaming and more. Furthermore, these problems extend into Adobe's Creative Suite, which can be the livelihood for many video editors, designers and developers. Thus, although there are some tips provided by Adobe to get around these issues, both Apple and Adobe need to resolve the bugs before someone gets hurt.
While not Adobe-related, ZDNet Australia's sister site CNET also found that Lion prevents users from backing up their data to third-party network-attached storage devices using Apple's Time Machine.
