Updated to 10.12.3.
To do so I used some tips from ITSage site (link:
www.theitsage.com/install-radeon-rx-480-gpu-macos-sierra/)
Steps:
1. cloned drive and EFI partition
2. Run updates using terminal instead of App Store, to allow me to edit the kexts prior to rebooting.
(sudo softwareupdate -i -a)
3. Then edited the
AMDRadeonX4100.kext and the
AMD9500Controller.kext in the same fashion as before.
4. After reboot, I ran multibeast to reinstall my audio (ALC1150 in my case), and rebooted again.
5. Lastly, I applied the "enable-baffin-cus-script" mentioned on the ITSage website to enable more computing cores on the RX480. The link to the script and the terminal commands are listed at the ITSage website link above in the section titled "Performance Easter Egg".
6. Reboot and test.
Much to my delight, there does seem to be a nice OpenCL performance boost with the changes.
Here's my latest benchmarks. Compared to my prior post, this is definitely better.
BruceX time = 8 sec now (was about 11 sec before)
