Not working with Catalina 10.15.1 build:19B88

[ukogonzalez]

Hi guys, patched yesterday and it worked. Just went off and when i wake up today, i got black screen in my external display, i wont even 4k@60hz, just 2k@60hz. Unpatched and patched again using v5, did sudo mount -uw / before, to avoid read-only, but nothing. Someone know why?

@ukogonzalez it looks like you forced the patch 2 times.. thus removing your original backup.. only way to recover is by reinstalling the os with recovery..

@serg-e what is the exact problem you are facing? did it ever work for you before?

Hi, I have problem with unknown version of CoreDisplay. It is the first time I try to install the patch on my macbook 2016. I assume it means the patch isn't installed, is that right?
