BALDY_MAN Posted July 10, 2025 Share Posted July 10, 2025 (edited) ok I was just experimenting with installed Tahoe beta 3 and removed WEG KEXT and boot argument from config .piist. did a nv reset. and it booted up a treat I was very surprised I just did a fresh install. without WEG.the install went well. but I think for me it was a bit smoother useing WEG Kext in the EFI Folder Edited July 10, 2025 by BALDY_MAN Link to comment https://www.insanelymac.com/forum/topic/361312-maybe-oob-support-for-rx6800xt-in-tahoe-beta-3/ Share on other sites More sharing options...
surenmunoo Posted July 10, 2025 Share Posted July 10, 2025 How long does it take to reach the desktop? I am thinking about getting rid of NootRX.kext because I hang on black screen sometimes unto 5 minutes before it hits the desktop. Also using 6800XT.

Cyberdevs Posted July 10, 2025 Share Posted July 10, 2025 @BALDY_MAN @surenmunoo as far as I know RX 6800/6900XT never required WEG NootRX or the Boot args, I've been using it on Monterey and newer versions of macOS without anything except device properties. I'm using MacPro7,1 SMBIOS and I don't have iGPU enabled (12900K CPU's iGPU isn't supported in macOS) Device Properties: <key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key> <dict> <key>@0,name</key> <string>ATY,Belknap</string> <key>@1,name</key> <string>ATY,Belknap</string> <key>@2,name</key> <string>ATY,Belknap</string> <key>@3,name</key> <string>ATY,Belknap</string> <key>device_type</key> <string>ATY,BelknapParent</string> </dict> I've been also able to boot Tahoe's installer without any issues from first beta. 3 Link to comment https://www.insanelymac.com/forum/topic/361312-maybe-oob-support-for-rx6800xt-in-tahoe-beta-3/#findComment-2836599 Share on other sites More sharing options...

surfinchina Posted July 10, 2025 Share Posted July 10, 2025 This works great on the RX6800! I just did what you said in DP and removed WEG, good to go - one less thing in EFI to cause potential problems... Thank you so much.

BALDY_MAN Posted July 10, 2025 Author Share Posted July 10, 2025 (edited) would the same adjustment work for the rx 6600 if we had the ATY Parent name? ie. it works on my rx6600 GPU build Tested for a USB STICK Added to system Added geek bench scores Edited July 11, 2025 by BALDY_MAN added more info Link to comment https://www.insanelymac.com/forum/topic/361312-maybe-oob-support-for-rx6800xt-in-tahoe-beta-3/#findComment-2836686 Share on other sites More sharing options...
