Mac OS X Secretly Cripples Non-Apple Software

spikedLemur writes: Vladimir Vukicevic of the Firefox team stumbled on some questionable practices from Apple while trying to improve the performance of Firefox. Apparently, Apple is using some undocumented APIs that give Safari a 500% performance advantage over other browsers. Of course, "undocumented" means that non-Apple developers have to try and reverse-engineer these interfaces to get the same level of performance. You really have to wonder what Apple is thinking, considering the kind of retaliation Microsoft has gotten for similar practices. (Anyone remember "DOS ain't done until Lotus won't run"?)
