The Runescape Macintosh Client is a planned piece of software that will allow Runescape to be played in a window on a Macintosh System running OS X. Jagex, the company that created Runescape, discourages the use of third party programs (All except the offical Runescape Windows Runescape Client). For this reason we will not finsh or publish the client. Jettic has requested to Jagex that they test the final and beta version of the software (To ensure it is free of keyloggers, malware, viruses, ect.). When Jagex potentially aproves of the software, they will be the sole distributors of the Macintosh Client.
