RX 470: Screen Tearing and Laggy Animation on Sierra

[hackmac101]

I saw a guide on this https://www.tonymacx86.com/threads/enabling-amd-rx-4xx-cards-in-sierra.201364/, but I cannot play the video. From YouTube I see there is a string of code to put on a kext, but can't find the code for RX 470.

I have the same exact problem. and everything I change causes boot up issues or it gets more laggy. any fix yet?

Your card seems to share the ID with the RX 480: 0x67DF1002

It looks like Gigamaxx has updated his methods in the first post of that thread; if you are using macOS 10.12.4 you need to update the AMD 9510 controller and the 4100 kext. (9500 controller and 4100 kext if you are using 10.12.3).

Can you tell me which lines I should change?? because I already did change some a few times but every time I do it ends up with boot up issues.

I just added 0x67DF1002 to the amd4100controller.kext file and this happend when I booted up again. Anyone know how to fix this or should I just reinstall mac os? I'm using Mac OSX sierra 10.12.3. My pc specs: AsRock B150M pro4, I5 6400, MSI RX 470 Gaming X 4Gb and an Samsung 850 SSD of 120Gb's.

Your line of purple dots is a kernel panic. Some of us got them from trying to use the AMD graphics card as the startup graphics card instead of the IGPU -- this is a BIOS setting.

There are several things that have to happen, at this point in time. the BIOS has to be set to use the built-in IGPU (or a second 'okay' graphics card to serve as the IGPU for those boards that do not have an IGPU.) The Clover system settings need to be set consistent for a computer that can use these type of graphics cards, as well as the hardware you have say iMac 14,2 for example. The controller kext (either 9500 for OS 10.12.3 or 9510 for OS 10.12.4) and the 4100 kext has to have the card ID in the right place.

You can find examples in these two threads:

https://www.tonymacx86.com/threads/enabling-amd-rx-4xx-cards-in-sierra.201364/

It can take some digging, but towards the beginning and the ends of these two threads there are posted examples that you can use that are similar to your hardware set-up that hopefully you can get your system up and running. It helps to post questions there as well.
