Anecdote: A few years back I wrote a Flash 8 piece for a relatively large ad campaign. The code ran fine on everything except OSX/Safari. Not only did it run poorly, but it had the strangest behavior: it ran poorly the first time you visited the site with Safari, but if you reloaded the site, everything ran fine. I bought a Mac mini to try to debug the problem, but without dev tools I was at a loss. After sharing my frustration amongst my circle of friends, a guy that did a lot of OSX work decided to take a look with some debugging tools. From what I recall, he discovered that Flash was making a perfectly valid call to an API method that should have been deprecated. The bug report was filed with both companies and I can only hope that one of them paid attention. The hack to get it to work on OSX/Safari wasn't pretty.
