Grim Reaper Posted June 15, 2013 Share Posted June 15, 2013 I got the EAH4350 (0x9553) fully working in 10.8.4 I got it working by reinstalling kexts from 10.8.2 : AppleBacklightExpert.kext v1.0.4 ATIFramebuffer.kext v8.0.61 11612 ATISupport.kext v8.0.61 11612 IOPCIFamily.kext v2.7.3 IONDRVSupport.kext v2.3.5 The cursor and windows move normally but Safari responds very slowly such as typing a URL/URI and loading graphics.

Grim Reaper Posted June 29, 2013 Author Share Posted June 29, 2013 I reinstalled OSX 10.8.2 and got the EAH4350 fully working again then cloned it to another drive and updated the clone to 10.8.4 and added 0x95531002 to ATIRadeonX2000.kext, fixed permissions, rebooted and, voila, fully working with 10.8.4.
