I have triad to install Simba on my Mac but to no avail. I'm going the Wine route, but somehow somewhere along the line I'm not doing this properly.
I have referred to this guide: http://villavu.com/forum/showthread.php?t=69693
At this point, I am willing to offer someone a cash tip in RuneScape for helping me with this installation. I'd be ever grateful if anyone is able to come to my assistance!
