Was listening to the Podcast. The deal with OSX 10.6.4 effected me. And I cannot believe Apple hasn't even come out and said anything about it yet. I reverted back to 10.6.3. Problem solved.
There was a one point a thread in the tech support forum about it, but basically, it is not limited to Runescape. Several games available on Steam have been effected by the update as well.
Ohh, is that why the thread on RS forums disappeared? I'm still a bit hesitant. I think I will wait for 10.6.5. It's already been released to developers.
Haha, screw it. Let's see if it helps at all. I trust Valve a little more than Apple right now. And apparently, Valve aided Apple with this update. Let's see. *Downloads*
