Okay, I have now done that, but there is another problem. Even though I am now playing oldschool through the client on swiftkit, the utilities are still for RS3 (hiscores, prices, calculators). Is there a way to change the format of the client to focus on oldschool data?
Before I start, the spec for my computer are Mac 10.9, latest java, and the newest version of Swiftkit downloaded. I had the problem with the black screen and changed it to the Dl version (which allowed me to play Rs3) but how do I get Swiftkit to work for oldschool Runescape? I've tried going to the oldschool webpage in the browser but it just gives me a black screen. Any suggestions?
