Hi this Work for me 1. Open /S/L/E find AMD7000Controller.kext 2. Right click and 'Show package contents' 3. Go to Contents 4. Copy Info.plist to your desktop 5. Edit Info.plist with text edit: a ) Use find tool to find 0x68181002 b ) Replace 0x68181002 with 0x68191002 c ) Save file 6. Copy Info.plist back to kext content folder 7. Back in S/L/E find AMDRadeonX4000.kext 8. Repeat steps 2-5. 9. After all just Repair permissions and rebuild kextcache - I use Kext Utility.
