I had the following error when i want to applying the Patchess on my
mbp4.1

an error occureed while applying the patches 1
Anyone
 
I have an updated WiFi card and GPU - so no patch required on my Mac Pro 5,1. has anybody tried OTA update on this config?

--> Tried it. The system is not recognized as a valid system for OTA. No option is shown. DosDude1 path install is all there is.

Worked. I installed minimal patches and cleaned up the WiFi driver to original without the extra plugins. Works with SIP.

no issues installing beta6 with 2012 MBP. HD 4000 graphics hack still working.

Acceleration fixed on DP6!

Method:
After replacing OpenGL.framework from 10.14.3 (as usual), re-replace the following file inside it from DP6.
Code: 
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libCoreFSCache.dylib

This fixes a "symbol not found" error in the Metal framework, allowing the system to boot to the desktop.

SkyLight/CoreDisplay wrappers remain unchanged.

Notes:
I would also like to take this chance to thank @jackluke for two discoveries that haven't been properly credited.
1. Thinning retro frameworks prevents APFS-related spam in verbose mode.
2. The SystemVersion.plist hack to allow installing over a "newer" macOS version.
Neither are directly related to acceleration, but I use both and never properly thanked you.

Secondly, I got kicked to the login screen once, shortly after booting, but no crash report was produced and it hasn't happened again. This could be a sign of an intermittent loginwindow or WindowServer crash though, so be warned.

Please report test results! Goodnight :)

Edit:
Found something weird: toggling Invert Colors causes the screen to blank out until moving the mouse. Can someone test if this happens on a supported machine? If not, I'll need to update the CoreDisplay wrapper most likely. Edit 2: So does changing the display resolution.

Edit 3: Siri, Find My, and possibly more apps are currently not working with this patch. Do not update. I'll look into a fix. Edit 4: My apologies, false alarm. I accidentally opened said apps from my DP3 partition. They are working fine, assuming you click on the right thing :oops:

Just updated Catalina Patcher to version 1.0.7, which adds full support for Catalina Developer Preview 6! Another HUGE thanks to @ASentientBot for his work in achieving full graphics acceleration on non-Metal video cards!

Edit: It seems that there are some minor issues with the non-Metal video card patches under DP6 (as noted in the previous post by @ASentientBot). I will release another update to the patcher once these are resolved.

Hi Colin,
There might be a problem with the patcher for MacPro 3,1 (with APFS boot rom and GTX680 and upgraded WiFi/BT chip) ). After running the install and then the post-install (w/ forced cache rebuild) I am getting a flashing No Entry sign and then the MP3,1 shuts down. Any other MP3,1 owner seeing this?
