I am on 19H1217 and can't see any updates available?

Also one thing I noticed on my Mac Pro running 19H1217 is that it fails to auto negotiate 1000Mbps connection with my router. I hard to force it manually, otherwise would be stuck with 100Mbps. I never had this issue in all my years using MacPro.

Updating is broken with the @dosdude1 patcher on Catalina unless you are willing to use the hacks mentioned on post #1.

I assume you already own a metal GPU?

Then check this thread and move away from the @dosdude1 patcher on your machine. All your problems will be solved. If this manual approach does not suit you try this tool. Although not supported with Catalina it will work beautifully on your system with a metal GPU.

I have CatalinaOTAswufix.app software update fix, unless the 19H1217 is in Beta?

I read about Opencore, so this OpenCore Legacy Patcher is just a shortcut, right? How can we be sure these developments (OpenCore & Legacy Patcher) do not carry some dirty trojans stealing our data?

This is a joke, isn't it?

This particular patcher here used on this thread was never open source unless the programmer decided to focus on other things, it had a tool to check online for upgrades and you all happily pressed ok whenever it came up with a message?

OpenCore and OCLP are both open source, the intention was to replace the closed source approach Clover (only usable with Hackintosh), you can download and compile it yourself. You can cross check each kernel extension included yourself, but yes, it is a ton of code.

The Trojan horse has already been placed by the U.S. government agency called NSA on your system, getting devices with Alexa and Siri functionality already got us far behind what the STASI or Aldous Huxley or George Orwell could ever imagine. All our devices are connected 24/7 to a big network which most of us do not really understand and certainly do not control.

You opened the can of worms - or to speak with a more colourful picture the box of pandora - already wide! And there is no way back.

It is highly doubtful the NSA gives a flyingF about what's on any unsupported Mac. Keep MRT and X-Protect up-to-date, install the Security Patches and point updates and it's all good. Used CatalinaOTAswufix.app, OCLP v.0.2.2 Boot Picker and @dosdude1 Catalina Patcher v.1.4.4 to make the this update to Security Update 2021-004 Beta subsequent build. Runs perfect, network performance intact. 😊

You can even download the latest Catalina built separately and give it path using dosdude1's patcher if you want to continue to use the latest updated Catalina. @K two is right above.

OCPL and the developers behind it have worked hard for the community. It does not have any Trojans and don't go by rumors. Thousands have downloaded it and many more will use it to give life to their unsupported machines.
Have not seen a single complaint on the forum about Trojan or malware.

It is safe. Cheers

Okay, this was only the half of the truth. I never use the Finder to replace files when I have opened a terminal anyway. You need to enter killall Finder right after the mount command. This restarts the Finder an make it aware of the fact that your root (file system ) became writable.

This worked!!

Thanks so much everyone who helped with getting the Japanese keyboard fixed in Catalina on my two unsupported Macs, this is working great now!!

I really appreciate this and my Japanese Wife appreciates it also.

Thanks again!

:)

I have a 2010 15" MBP running Catalina 10.15.7 (19H1217) with Catalina Patcher. I've noticed that about maybe 1 in 10 times it wakes from sleep, the cursor is stuck. The computer continues to function and you can actually "mouse around, select menus double click, etc - just blind with no curser which remains in the lower right. Any ideas? Could this be due to the patcher or one of the graphics patches? thx.

Sounds like a job for SMC reset. 🧐

I mean it's worth a try but this type of scrambled graphics doesn't fit the usual symptom of the SMC which is usually more power/battery related.

Did you apply the post install patches after the reboot . Did you select legacy graphics.

Yes. I’ve done a re-install of all recommended patches. All is fine ‘most’ of the time. As I said about 1-10 times wake from sleeps results in this weird graphic glitch where the mouse cursor is motionless on the screen. You can still mouse around, you just can’t see the arrow cursor. I have been re-starting whenever this happens.

Yet another SU2021-004 Beta update w/the usual tools. Used CatalinaOTAswufix.app, OCLP v.0.2.3 Boot Picker and @dosdude1 Catalina Patcher v.1.4.4. Runs same as previous, too good to be true. 🥳

MBP4,1 17" (Early 2008) successfully updated to 19H1317.
I use CatalinaOTAswufix.app to pull the update, then boot via alt-key into USBOpenCoreAPFSloader3.app and run the macOS Installer from there, followed by booting via alt-key into macOS Base System (external USB) created by dosdude1'e patcher, apply the appropriate patches plus force cache rebuild.

K Two, I am interested how your update process works, and what the advantages are with your chosen method via OCLP. Would you be so kind to briefly outline, how you do it? thanks in advance.

This is very bad from you.
Anyway the code is open source, so if you have any doubts just read the code and compile it yourself. Reading your comment I doubt you will understand any single line of that code.

Functions the same as the OpenCore3 USB, finds the macOS installer to complete the update on our unpatched ROM, non-Metal Macs w/Big Sur also installed. The @jackluke method is fine, very reliable. 🧐 Your update description is very clear, others can follow. 🧐

macOS Catalina 10.15.7 (19H1217)

I download macOS.Catalina.Patcher.dmg to make a bootable USB stick for other MBP but I get this warning:
What is the problem?

Thanks
