Hello ! some news of my issues !
Your hardware profile says Asrock Z390 Phantom Gaming. Is that the mobo you are using ?
That was indeed my first build ! but I move to this one !
Please check if OpenCore Configurator --> Misc --> Security --> SecureBootModel is set to Default (not Disabled). This is a prerequisite for the OpenIntelWireless driver (AirportItlwm).
Does this happen on certain pages only or on all pages? Have you tried clearing history (History --> Clear History...)?
It was that ! (SecureBootModel) Thank you !
But that's where the trouble begins haha
Regarding the problem on Safari, I had no problem on my first attempt to install
(I had used the EFI provided in the first post but putting iMac20,2 in the model and everything worked fine)
When I used the wireless EFI I encountered other issues.
A few plug-ins in my DAW just didn't want to run.
I managed to get one to work (after some hard research) by executing a command in the terminal that allowed to disable Graphics acceleration for plug-ins "com.fabfilter.Common GraphicsAcceleration -int 0"
But some just didn't want to boot, or made me crash my DAW.
So I decided to do a new installation this morning, based on the EFI from the first post (OC-066-VISION-D) and based on the iMac20,2 model.
Everything works very well (safari, daw, plugins ... without any intervention)
But when I switch on the EFI Wireless (By recovering all the serial numbers etc) the problems on safari, my DAWs and plug-ins come back... But wifi and bluetooth is ok haha.
thank you in advance for your help !
