Hello to all of you and good day (and congrats for your great work). The details of my system can be found in my signature. I have updated the AMD patches (setting correctly my core count). I have updated opencore (0.85). I have updated the kexts to the latest ones (at least I think so). Is...

My setup.

Great! I have updated my EFI too, to the latest kexts and 0.84OC.

Many thanks Shaneee! You are perfectly right. I was experimenting before I have seen your post. In the beginning I set to 0 both Quirks, and whilst I could boot into macOS, I had a black screen at win11.:D I then came across this topic...

Hello my friends. I would kindly ask for your assistance/advice on the below. I have a dual boot system. Win11 and macOS Monterey. You can see the specs in my signature. I recently upgraded my CPU to Ryzen 5 5600x. The reason I did this was because I wanted to enable the AMD smart Access...

Yes please, why not. What will be the difference if I use your ACPI files? Is it better than using a kext? Thanks neighbor!

Sure. I amended the 1st post. Remember this Efi is for the specific Mobo (with the intel wifi/BT and the specific USB ports), a 6core Ryzen Cpu and a 6000 series GPU. imessage and facetime also work. I have deleted in config plist/Platform info the information about Serial number, UUID, MLB and...

Hi to all. Just wanted to share my experience as it may help others with similar GPU. I was always getting a black screen after the 1st Apple Boot Logo with the 6600xt even if I had added in the boot args the "agdpmod=pikera". I don't know if this has been mentioned but the way I made it work...

Do you know if Ventura will support Navi24 GPUs?

Is this kext better to use with Big Sur as well?

Up to now the boot time seems to be the same as before. I also installed the nvmefix.kext just for the sake of good order. I will monitor the situation to see if I get any problem in the long run, and hope that the updated firmware of the nvme was indeed of assistance. I would like to thank...

Thank you all for your advices. Just for testing purposes I have proceeded in cloning my sata SSD to the nvme. Everything seems to be working OK up to now and the speeds are fast. As a note, I read on a relevant post that you need first to update the firmware of the Samsung nvme to the latest...

Really...? It is the first time I hear this. So, this problem only occurs with Samsung nvme ssds or with all nvme ssds? Fyi for the time being I will not upgrade to Monterey as when I tried to do so I had all shorts of problems like my ethernet and BT not working etc.

Hi! My rig can be seen in my signature. I will replace my sata samsung ssd with a samsung 980 Nvme. Do I need to add any specific kext for the nvme to be recognized and work normally in Big Sur or there is no need for a specific kext? Many thanks!

Hi I am a little confused. I am downloading right now Monterey stable release 12.0.1 via the normal update method in Big Sur. I am using OC 0.74 and the SecureBootModel is set to default. Should I set it to "disabled" before the PC restarts? Also my SmBios is iMacPro1,1. Is this OK for...

I had the same problem. I downloaded the update from Mr Macintosh website and run the installer.

Also keep in mind that GTX 970 is supported up to High Sierra and you need to install the nvidia web drivers.

Apologies, I just seen the below tutorial and this fixed my issue. More specifically I added unfairgva=1 as boot argument. https://forum.amd-osx.com/index.php?threads/fixing-green-screen-drm-on-bigsur-for-appletv-and-apple-music-streaming.1476/

Hello to all. The details of my system can be found in my signature below. I am on Big Sur 11.5.1 with SmBios iMacPro1.1 (and opencore 0.71) I cannot get the DRM to function properly. Netflix can only be used in Chrome. When I use Safari I get a red screen (but I can hear the sound). In appleTV...
