Incredible work on this. Have you upgraded to MacOS 14 Sonoma yet? I'm currently using it with no issues aside from a graphics card problem, which is potentially related to a PSU issue.

Thanks. I hate buying another PSU but if it solves it then its worth the purchase. Will post the results here too in case others are having the same issue and looking for a solution.

I'm currently running on Sonoma with a 6950XT. Most of the time everything runs fine, but I'm starting to use apps that are GPU intensive, and it *always* reboots in the middle of processing. I've tried the "AMDRadeonNavi2xExt" and "NootRX" kexts, tweaking the BIOS settings to remove...

I'm having the same problem. I'm using the "AMDRadeonNavi2xExt" kext which works perfectly (benchmarks over 215k for metal and 122k for OpenCL) except for certain graphics/video apps forcing a restart. I tried using XMP II as recommended by the OpenCore docs, tried XMP I, set v-droop to level 1...

So far the solution here is working: https://www.tonymacx86.com/threads/sonoma-videos-laggy-several-hours-after-reboot.328021/post-2390212

Thanks, Ill get ready to try the device-id spoof. Is this the best guide to use for it?: https://www.tonymacx86.com/threads/radeon-rx-6950-xt.320302/page-2#post-2352873 iGPU is enabled, but I didn't see an option to set the framebuffer so I assume its using the default value. I have a SSDT name...

Thanks for your reply. For streaming I used Brave web browser and Safari, and for local vids I used vlc media player and the built in quick view (press space bar on a media file). The problem happens on both streaming and local, but only after the computer hasn't been rebooted for about 4 or 5...

I have an ASUS Prime Z490-A running Sonoma 14.1 with a Radeon RX 6950XT. I can't tell if its a graphics card issue or something else, but after I reboot the computer I can watch any video (local or streaming like youtube) with no lag. After a few hours, watching streaming or downloaded videos...

If you search outside of the tonymac site, you'll find the problem has been reported many places. In short, no one knows what's causing it or how to fix it. Ventura is also having the same issues. Its also happening on m1 computers. Apple is also stumped and doesn't have a solution to fix it yet.

Thanks for the link. I already had SecureBootModel set to default, and my SystemProductName was already set to iMac19,1. I also updated all my kexts and am on OS 0.7.8 but it still won't find any new system updates.

I'm having the same issue. Also confirmed all the settings are set to what the community here is recommending. Is there anything else to try?

Big Sur with very few issues. Use the EFI that jacobbdavis made: https://www.tonymacx86.com/threads/lg-gram-17-17z90n-end-randomseed.305462/post-2251638

I tried both the default config file posted by OP and the config file changed with the values you posted (and double checked using hackintool) and I’m still having problems that I’m not sure are hardware or config issues. The Ethernet works for a few seconds, connects and will even load a page...

Someone said this guy got it to work and he uploaded his EFI and listed what he changed in the BIOS: https://github.com/whca/lg-gram-17z90n-EFI In the readme, (translated using google) it says "OpenCore0.6.6, the boot card EB, cannot be used temporarily". I don't know if this means he's also...
