Apply patches again and force the cache rebuild - as always.

Before I asked here, I tried this more than once...

Please use this thread and do not use the @dosdude1 patcher on your machine. It is an ridiculous idea to use it, especially because you have this RX580 which would need OpenCore anyway.

OK, thanks. I used dosdude1 patcher with all my unsupported machines (since Sierra and HighSierra), and mostly didn't have any issue, so I thought it was the best way to install Catalina even on my MacPro. And until build 19H15 I didn't see any issue too. Here we say: don't change a winning crew... but I guess you you are right: OpenCore will be a better choice for my MacPro. Thanks again.

OCLP is another patcher named OpenCore Legacy Patcher made by developers that can patch BigSur and Monetery. Like mentioned you can also install security updates for Catalina in the post above by @K two

OpenCore Legacy Patcher

OCLP is not a patcher, despite of the name. Does not patch anything in macOS´s. It´s a completely different approach.

Well you better get the Dortania link and definition corrected then. I just mentioned what the link to the Dortania Github said. And the image below says it too.

This is a pointless discussion!

The main goal of this tool is to use opencore injection instead of classical patching (You know what a patch is and why this phrase is used in software industry?). So technically this tool does not try to achieve changes or adaptions by patching.

But:
Recently with the introduction of the legacy video patches (watch the wording) this technology is used by this tool, too. There is a drawback: You are loosing the ability to apply OTA delta updates.

IMHO the phrase Patcher has been used to pull all the users into this boat. Everybody in this land of unsupported Macs knows what a patcher is and why you have to use it.

Technically we have three type of unsupported legacy Mac systems right now:

1)
Systems not needing any patches or injections, these need or use OpenCore only to install the new macOS and to enable the Apple software upgrade. Technically you could disable OpenCore after installation and boot using a special boot arg until you want to update, again.

2)
Systems lacking of (some minor) software support by the recent macOS versions which can be fixed by injection of some (sometimes adopted) kernel extensions (like upgraded MacPro, upgrade metal enabled iMacs, more recent 2013/2014 Macs), OpenCore is needed to install, boot and even run the new macOS versions.

3)
Ancient legacy system mostly with pre metal video cards needing real patching. These need OpenCore to install, boot, and run the most recent macOS versions. One could build a patcher not using OpenCore at all (and we had/have this with the micropatcher).

But this does not make the things better or more easy. Especially the update process without OC will be broken as you can see with the @dosdude1 patcher and Catalina. Because of this fact I stopped working on the micropatcher. It would need OpenCore to update in late summer after the last full installer has been published by Apple.

And OLCP provides the most sophisticated tailored and preconfigured OC versions I know of.

Even I'm sure you have all reasons to suggest OC, i saw that the installation can be a little tricky, and shouldn't be used with patched macOS. So for now, if it's possible, I'd like to recover my patched Catalina. But If I reboot with patched USB stick (I tried with the one I upgraded the MacPro some day ago and with a rebuild from scratch), I'm unable to apply patches or re-install Catalina at all: reinstalling Catalina gives an error message, while applying post-install patches seems to do nothing. With DiskUtility from patched USB stick, I see all partition unmounted and I can't mount them.
Before throwing away the work I done, cloning back to main disk my previous Mojave installation, is there something I can try?

Greetings,

Currently rocking MacPro's 2008 & 2012 both patched to Catalina with dodude1 patchers - both are running Metal GPUs. Both have update WiFi/Bluetooth cards which should be compatible, though to be honest it would not be an issue if neither worked.

Seems like OCLP is the way forward for Big Sur and/or Monterey - can anybody tell me how performance is on these machines with Big Sur ? And any indications so far on Monterey ?

I'm wondering whether to give it a go with Big Sur or (as per recent plan) wait for the next Mac Mini update with M1X or M2 (but of course no ETA on those)...

Using OpenCore you would not need a patcher at all to use Catalina on your systems!! Take a look here.

Check the same thread out for Big Sur experiences and current problems especially on MacPro5,1 systems. OCLP is a tool which generates OpenCore configs automatically while the thread I mentioned gives you a in depth guide how to do it manually.

I finally managed to get Catalina (10.15.7) running on MacBook Air mid-2011 13' with 1.4.4 patcher. Didn't do anything major, after Nth time trying to put the image on the USB the installation finally booted up. However, now I'm having some WiFi issues. It stopes working/detecting networks once I close the lid of the laptop and open it back up. Maybe going to sleep kills it? Disabling and enabling WiFi doesn't seem to help. When I restart the laptop, it seems to be working again and detects WiFi networks again. Any help would be much appreciated. Thanks for reading.

I have the same problem. Did you find a solution?

This normally happens when the certificate of the app is not allowed by Catalina.

You can use this command in terminal window

Code: 
codesign --force --deep --sign - /CatalinaOTAswufix.app


After this you will be able to open the CatalinaOTAswfix.app

or if still can't launch the app, this: sudo spctl --master-disable

How do I revert this commands in macOS?
Code: 
codesign --force --deep --sign - /CatalinaOTAswufix.app
Code: 
sudo spctl --master-disable



Thanks

Quickest way to do so, open Terminal, type "codesign --remove-signature" followed by a blank space, then drag & drop the .app into Terminal's window and hit Enter. (the app should be CatalinaOTAswufix.app)

Hi all,

I don't know if this is the right topic, if not - delete please.
I recently installed Catalina on my MacPro5,1 via OpenCore 0.7.0 Martin LO package, which went perfectly fine. Also the latest security went w/o problems.. the system runs very fine with single X5690, 24GB 1333 RAM and NVidia GTX660.

The Wifi did not work OOTB but could be activated via config.plist, which works but my System Profiler shows following:



Also Airdrop is completely missing, which is something I used now and then.. any chances to get that working with the old Wifi? Or do I need to upgrade my Wifi and BT module?

Hi! Move over to the OpenCore on MacPro thread. I guess you will get more attention there.

I really love this thread, but I have just bought a second hand macbook pro 16", and although is completely out of the theme, it´s a relief that everythig works as it should out of the box. Sorry if it is completely out ofn the thread.

Smooth update to 19H1323 w/CatalinaOTAswufix.app, OC and Catalina Patcher v.1.4.4. Also, needed MRT updated and the Validation Patch update. Runs cool and snappy on this "primitive" old Mini. 😎

Thanks. I had never used that so far.
Do you recommend to install all updates? I'm actually happy with 19H1217 so far.
Click to expand...
Happy w/19H1217 DO NOT install ALL of the updates. Software Update CP will offer some choices, if you don't want them opt-out of Betas, the small blue text below the CP gear is the option. After opting-out, re-run SilentKnight it will offer MRT and X-Protect, only. You can update both. MRT may require two attempts. How does the cMB5,1 perform on Catalina? We have one on Mojave, see the signature, last entry. 😎
