DiscoDancer Posted March 22, 2020 Share Posted March 22, 2020 Specs:- CPU: 9700k MOBO: MSI Z390 Gaming Pro Carbon AC GPU: Sapphire 5700XT Nitro The problem I am facing is with the way RGB is behaving in MacOS. I have couple of fans connected to the ARGB and RGB headers on my motherboard and the motherboard it self has some lights. The problem is that when I boot into MacOS the RGB freezes completely and doesn't recover even after rebooting into windows or shutting down the machine. I have to completely disconnect power and wait for 10-15 secs for the RGB to reset. At first I thought that it's a USB issue as there's an internal USB device present called 'Mystic Light' so I mapped it in the SSDT but that didn't fix the problem. Then I put in the limit patch and removed USB map to inject all ports that didn't fix the problem either. I also set up proper 'EC' device and still nothing. I have tried just about everything I could I even tried purposefully breaking nvram support then setting up RGB in windows and then booting back into MacOS. I am completely out of ideas and would be grateful if someone more knowledgeable than me would like to have a look. I had initially set up the machine with OpenCore but then I switched to Clover thinking OC might be the issue so I will attach both OC and Clover configuration. They are WIP as I am stuck on fixing this problem before jumping on other things. Clover.zip OC.zip Link to comment Share on other sites More sharing options...
DiscoDancer Posted March 22, 2020 Author Share Posted March 22, 2020 I managed to fix the problem. The solution is omitting the Mystic Light internal USB device from the USB map. Link to comment Share on other sites More sharing options...
