Patch for macOS Catalina 10.15.6

[guilhermefilippo]

Hello!

Does anyone have the patch for macOS Catalina 10.15.6? I just updated and my monitor lost its 2560x1440 resolution.

Thank you.

Be careful: Having no working version of CoreDisplay requires you to reinstall the OS.
It might be wise to undo the patch before trying to redo it using: ./CoreDisplay-patcher.command unpatch
Do you want to continue? [Y/n] Y

The code is still the same. Patch seemed to run, but was probably for the wrong version.
If you are running a new OS, run ./CoreDisplay-patcher.command md5 and ask the maintainer of this script to add support for your system.

The problem was the read only mode. I just did "sudo mount -uw /" and ran the script. All right!

Same error for me, using patch v5 got me stuck in the apple logo boot screen.
