Thanks a lot for your great replies!
I cleaned up a bit the kext folder by removing the unnecessary ones, and added instead what I needed (for example the one for the 10gbit Solarflare card) ; I used OCSnapshot in Propertree to update the config.plist.
I use the iMac 19,1 SMBIOS as well, and properly generated all needed data. Monterey is installed on a NVME drive.
On the same system, but on another SSD, I still have the old install with Clover and Catalina: over there, I used the iMacPro SMBIOS. I'll keep it as a backup in case of problems, or in case specific software runs better with that combo.
I think it freezes when I reboot, not when I shutdown; I'll try to just shutdown all the time and see if it happens again.
Another weird thing: I have 2 monitor plugged to the DP ports of my RX 570, and everything is fine. At one point I tried instead using the HDMI port on the mainboard, since you patched the framebuffer: the port works, but the screen was showing erratic behavior, so I put them back on the DP ports.
I like to keep that HDMI only as a backup in case the video card fails
I enjoy a lot my build overal, thanks a lot for your help!
Hi @thepawn -- I am curious to see why it is freezing on reboot. I'll search for that command. The only one I know is
pmset -g log
. Would you mind trying that next time it freezes? I use that primarily to debug sleep/wake problems, but it may show what is happening.I haven't played with the iGPU framebuffer in a long time. I think it was back in Catalina. I managed to get it working and initially, it had problems redisplaying an output after sleep/wake. I had to unplug and replug the cable from the port. I fixed it with a boot argument, but after that, I never really checked on it after multiple OS upgrades/updates and multiple OpenCore updates. I think I've been reading that the HDMI isn't really optimal for MacOS and that the cable may make a difference. Anyway, I just moved entirely to the eGPU and DP.
