Let’s take a look at the Catalina 10.15.3 Update (19D76) to see what’s new.

#Macos catalina patcher download full#

MacOS Catalina 10.15.3 is now available for download as a full installer.app, delta and combo update.

Make sure that WiFi is set to Native-Plus and Boot Plist patching is enabled.MacOS Catalina 10.15.3 Update (19D76) is now Available macOS Catalina 10.15.3 Update (19D76) is now Available.ġ0.15.3 is Catalina’s third update and was released about a month and a half after the 10.15.2 Update.

Once it's done, go back to the Advanced Patches screen.

Press Start Unpatch Kexts and let it go.Change the mode from Patch Kexts to Unpatch Kexts.Click Advanced Patches and enter your password.Open Patched Sur and go to the Patch Kexts section.If you update to 11.6.5, the new patch will be used by default.Make sure you've made a new installer usb, you'll get errors if you neither the usb nor the pre-downloaded patches (obtained whenever you update or make a usb) isn't using the latest version.Non-metal Macs can no longer go past the verify stage (instead of just a warning, it just stops them there), not like they were ever supported anyway.You can no longer use the beta track, not enough people use it for me to justify keeping it (I haven't seen any recently), you can still download the beta installers on your own and tell Patched Sur to use those if you want.(It actually looks like it's doing something now) Added a fix to the terrible downloading screen when making an installer.There was many dead links in the patcher that should have been fixed in v1.0.1, but they're fixed now.Possible fix for the big patch kexts error (1x127).New WiFi Patch! Native-Plus is now the new default WiFi patch, the same one from Mini Monterey.You'll have to right click on the app then press open or use System Preferences to launch it. Note: The patcher isn't currently signed.It did introduce personal hotspot support for me, but I can't test WPA2 Enterprise and it was always stable for me, so I can't say much about the other problems. The current patch works most of the time but personal hotspots and WPA2 enterprise networks don't (always) work plus WiFi is just in and outįor some users. I wanted to try the WiFi patch from Mini Monterey on Big Sur.
