1. Go to top tool bar and select Finder, then scroll to Preferences and click. Check the box next to Hard drives. Now all attached drives will appear on the desktop.
2. Download xCode from Apple App Store.
3. Download kext wizard app.
4. Open the drive with 14.4 on desktop and select System, then open Library, then scroll to Extensions folder and open. Find the AMDRadeon5000kext and right click on it. Choose “show package contents”. You should see a Contents folder, open it and drag the info.plist to your desktop (do not try to edit inside the folder). Click on the desktop and go to top tool bar and select File, scroll to New Folder and select. Name the new folder backup info plist. Drag a second copy of the info.pmist to it as a backup.
5. Right click on the info.plist on the desktop and select Open With “xCode”. Scroll to the IOKitpersonalities arrow and open. Now open the Vega 10 tab. Use cursor to select an Device ID like 0x68AO1002 or one of the first few there. Click on it and replace the 68A0 with 66AF. The finished edit should be 0x66AF1002. Make sure not to add any spaces or delete any space between the IDs that are there. Now go to top tool bar and hit File-Save. Close the xCode window.
6. Now drag the info.plst back to the Contents folder and make sure to get BOTH “Authenticate” and “Replace” prompts, if you don’t get replace prompt hit cancel at password window. After replacing the plist you should see it drop into the proper place where the original was.
7. This is the most important part open Kext Wizard and select System/Library box and the make sure to select the correct drive at the bottom (target disk) before hitting Enter.
Now it should be ready for reboot and testing. Good Luck!
