Deep_Thought Posted December 8, 2022 Share Posted December 8, 2022 Hey guys, I was running Catalina for a long time but my R9 290X kinda blew up. Since I wanted to get a new 6900XT anyway, this was the perfect time to upgade. Problem 1: 6900XT support was only added in Big Sur 11.4, so I would have to update from Catalina. Problem 2: My 6900XT is the XTXH GPU variant which is not directly supported in macOS. I want to install Monterey with OpenCore. USB stick creation by OC install guide, also integrated XTXH hack as described in https://github.com/TylerLyczak/Unsupported-6900XT-Hackintosh-Fix. Alas, the installation hangs quite early at #[EB.LD.OFS|OPEN!] Err(0xE) <"usr\\standalone\\OS.dmg.root_hash"> if I read the log right. I attached my EFI folder and log from OC from the last install attempt. If anybody has any insight how to get the installer working, it is greatly appreciated.

If you got no option to disable it in BIOS then disable it with Kernel - Quirks - AppleXcpmCfgLock to Yes.

Deep_Thought Posted December 17, 2022 Author Share Posted December 17, 2022 (edited) Indeed, AppleXcpmCfgLock was the culprit. Funny enough, I thought I had it enabled but must have missed it during installer creation. Now the installer boots to the Monterey install program. Let's see if there are any more obstacles. Thanks a lot! Edit: Installation went without a hitch and Monterey is up and running. The GPU was recognized immediately and runs smoothly. Now it is time for post-installation cleanup and system setup. Edited December 18, 2022 by Deep_Thought Link to comment Share on other sites More sharing options...
