Hi, I have a Mac OS X 10.4.11 and I'm having trouble starting GIMP with it. I went to the downloads section on GIMP's website, then followed the instructions to the site where I could download it for Macs. I downloaded the Tiger PPC version of GIMP 2.6.3, and after opening GIMP I clicked on it (it was in my dock), but it told me it required Apple's X11 to start. The exact message was "Failed to Start X11: Gimp.app requires Apple's X11". So I went to the Apple site and downloaded X11 Update 2006 (I couldn't find any 2008 version of sort), but when I clicked on it in Finder it said "This system does not need this update". But I tried to click GIMP again and it still won't work. Can anyone help?
