Support for 10.15.4 (build 19E287), MacBook Pro 13" 2016

[thirstyraven]

I have the MacBook Pro 13" late 2016 model running the latest 10.15.4 (build 19E287) with an Intel Iris Graphics 550. The script didn't detect my build, and forcing patch v5 didn't work.

However, I'm still able to only get 30 Hz from my 3840 x 2160 external display. I know that my adapter and HDMI cable support 4K 60 Hz, because I can natively get 4K 60 Hz on my external display with my MacBook Pro 15" 2018.

I tried forcing 60 Hz with SwitchResX as well, but I was unable to activate.

What next?

I also have similar issue after update to 10.15.4. I tried to unpatch and patch it again with v5. But after that my mac was stuck at start on apple logo (progress bar almost full 100%). I restored backup and it boots fine. Hopefully we'll get updated version soon, this patch is just too good to not use it (and be stuck with 30hz)

It works again on catalina 10.15.5

@radKoz I'm on 10.15.5 (19F101) right now and patching v5 doesn't work for me.
