rmmcwh replied to mucha's topic in ATiI have a Diamond Sapphire 5770HD, and OS X 10.6.7 using current Snow Leopard ATI kexts from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]. I have tired to follow your steps, using 0xED as the hex editor. I cannot do a search in framebuffer.kext like you indicated, nor can I find the place to make edits. Not sure what I am doing wrong. Thank you for your help.
