Hi all,

I just purchased an RX 5700 XT as an upgrade for my 5,1 which was previously running with an RX 580. I removed the post-install patches using OpenCore Patcher before replacing the GPU, but upon boot, it seems to hang every time around the 35% mark and refuses to boot into the OS no matter how long I wait.

I am still able to boot into the OS with the 580 back in place however. Judging from the boot sequence, the Mac with the 5700 XT installed seems to be freezing/hanging right...
