So I recently updated to 10.15.6. Whenever I boot now, it boots into 1080p max resolution on my 4K monitor via DisplayPort. It was working fine before!
Weird think is that when I disconnect the cable, reconnect it and then set it to 4K in display settings, it works again. But that means I have to disconnect and reconnect my DP cable every time I boot.
Latest Clover and kexts like Lilu...
- Sapphire Radeon HD7950
- MSi Z87-G43
- Intel Core i5 4670k
- 27 inch 4k Monitor via DP
So, here's what i think clover do when it patch ati framebuffer, first it read a cached kext, then it search the original hex value of the connector, then it changed the value with the new one. Is it correct? now, here's what i find confusing... let's say that i want to patch AMD7000Controller.kext, in that kext, i want to patch "AJI" framebuffer with a new value, so clover try to find the hex value of "AJI" connector then replace it with the new one, simple right? but when i search the AMD7000Controller binary file for other framebuffer, some of them didn't exist in the binary, for example, i tried to patch "Ramen" framebuffer, from various source, it said that:
Ramen (6) @ 0xeba70
LVDS, HDMI, DP, DP, DP, DP
So i open a hex editor and search for:
but, it turns out that hex editor couldnt find that hex value in AMD7000Controller,
most of the framebuffer exist in the AMD7000Controller, but some doesnt, If this is the case, then, where does clover find the original framebuffer to be patched? am i missing something?
So the problem is: I bought the iiyama to use as a 3rd monitor. Previously I was using the DELL through a DisplayPort, and the Phillips through HDMI which worked fine. When I first got the iiyama monitor and I plugged it in everything was working great. The next day I boot up my machine and it will freeze on a black screen after I boot macOS through the clover bootscreen. I unplugged the new monitor, restarted the machine and it would boot normally again.
I started trying some different inputs and nothing seemed to solve the problem. All that I know is that the machine freezes as soon as I plug in a 3rd cable, doesnt matter if its HDMI or DP. I even bought a HDMI to DP cable for the Phillips, to see if it was an HDMi problem, but even then it doesn't work. I've also tried powering the monitors off and turning them on once the machine has booted. Also no luck.
Any help from one of you Hackintosh guru's would be highly appreciated. I bought the 3rd screen to make working from home even more efficient, but sadly enough my build won't allow me...
I am planning to make my hack ready for post High Sierra macos, finally xD So I was looking for a proper AMD GPU, but it is not that easy to find a proper, recent guide for that. So compared a bunch of AMD GPUs, and this one seems to suit my needs the most: XFX RX 5500 XT Thicc II Pro 8GB
Will this graphics card work properly in macos? And what macos version is the minimum here? I read so many contradictory statements, some older said that the RX5xxx support in macos still sucks and is much slower than in Windows. Is this still true? I currently have a nvidia GT1050, I guess it still will beat that nvidia card?
Would this work with old but gold clover (recent version) + lilu and whatevergreen, or should I switch to OpenCore then?
