macOS 10.15 Catalina on Unsupported Macs

[Dilli]

1.-  Move a copy of my macOS Catalina Installer to Applications from my USB stick
2.-  Run macOS Catalina Patcher in a supported MBP running macOS Catalina (19H2)
     No Security Updates installed, no Gatekeeper, Xprotect or MRT updated
3.-  Browse for the copy of my macOS Catalina Installer and select the app from Applications
4.-  Select the Create a Bootable Installer icon
5.-  Format a new USB stick as Mac OS Extended (Journaled)
6.-  Select the new USB stick in the Option "Create Bootable Installer"
7.-  Insert the Bootable Installer stick in a Unsupported MBP
8.-  Convert the HDD as APFS (Unmount, Edit > Convert to APFS...)
9.-  Select the Reinstall macOS option
10.- When reboot I did not see the screen with the custom APFS boot implementation
11.- The booting screen stuck and I had to hard reset pressing Power in my MBP
12.- I did not install the macOS Post Install Patches (Because the are optional and when
     I turn of the MBP again appears the first time setup of macOS)
13-  Install 2 patches updates that were availiable for the MBP model

A) I can not update my MBP
B) I try to install the Security Update 2021-003 (Catalina) using a USB stick
but I does not work.

What am I doing wrong?

Thanks

Dont be nervous when you try to upgrade. I had similar tensions and finally succeeded. First do your research well. See many videos available on YouTube. Then visit DodDude1's webpage on a secondary iPad or Mac as a reference to look at every step while upgrading your machine.

Don't forget after upgrade you have to again press option key in boot picker screen and go to the installer and select post install patches for your machine.

Post install patches are not optional. That is what makes your machine work with Catalina. When you enter your machine model type as in your case it is 8,1 the patches relevant to your machine will get installed.

Hope it helps.

You have to select your machine type for post install patches. Also after you upgrade you cannot just do software update over OTA. After every update even security updates you have to run post install patch for your machine type.


Follow exactly the dosdude1's patcher after opening it on your desktop.

Mr. Dilli— No offense, but I don’t think that “ don’t be nervous when you try to upgrade” is any kind of viable, tangible advice. We are updating macOS with security updates—not losing our virginity here. If you are going to advise this person, they need tangible, concrete, advice—a guide. And, as far as I know, just about everyone in this thread has successfully updated their dosdude1 Catalina build(getting the security updates) by using the guide from post:

#13,956

The link above is what has worked for everyone here. perhaps I’m wrong, but it does not appear that this person is trying to upgrade from Mojave or high Sierra to dosdude1 Catalina. They are already on dosdude1 Catalina, and they want to update their build, (=get the security updates). And right now, the best way we know to get updates is #13,956.
If you have another guide or method, great, but please direct us to that step-by-step, clearly laid out guide for how to do it.

Ok . It seems you got carried away with just the first line of the post. It is not a question of offense.. There is no need to advocate. It would have been much clearer if the actual poster would have mentioned " security updates" on the subject line. You have pointed to the guide as per the link. Nothing much to add so far. Have a Nice Day

If I download from https://github.com/jacklukem/CatalinaOTAswufix

I get CatalinaOTAswufix-master.zip

If I Unzipped I get only a folder with the name CatalinaOTAswufix-master

If I renamed CatalinaOTAswufix-master to CatalinaOTAswufix.app and move to the desktop I have an error:

Open CatalinaOTAswufix app. (If it gives you errors, move the application to your Desktop. Make sure it's the actual application and not an alias. Delete it from your Applications folder once you move it)

Click on "Software Update Fix"

The app is on Desktop giving me an error

Generally, apps that you download from outside of the App Store in macOS will always?/often? need to be given special permission to be opened in [system preferences] —> [security & privacy] —> [general] tab.

Trying to run a .zip file or trying to run a folder?

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

You can use this command in terminal window

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


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

Try this: https://support.apple.com/guide/mac-help/mh40616/10.15/mac/10.15

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

if still can't launch the app with above methods, remove any downloaded copies of the app, then download from here: CatalinaOTAswufix.app.zip

possibly download it zipped (Safari Preferences General uncheck "Open safe files after downloading"), then try unzip it with "The Unarchiver" or "Keka" and retry to launch.

For your MacBookPros to update Catalina you probably don't need any USBOpencoreAPFSloader .

Which Mac are trying to update Catalina ?

If you already install the update reapply from dosdude1 post install patches selecting "Force cache rebuild".

Or try after power on to hold alt option key for 10 seconds, then at apple startup manager select "macOS Installer", otherwise select "Catalina"

If still doesn't work try using this USBOpenCoreAPFSloader3.app.zip as "EFI Boot" from apple startup manager targeting "macOS Installer" or "Catalina".

If none of this worked simply reinstall Catalina through dosdude1 patcher, data are kept.

Help... some how my audio hardware support is gone after 19H524, any idea how to get my Audio back?

Did you find the trick to get sound back? I've the same issue on my MacPro 2009 after 19H1217 upgrade, until Catalina 19H15 alls seems to work right, but after upgrade through OTAswufix.app, internal audio exit disappeared. I reapplied dosdude's patches: first time without checking "Legacy Platform Compatibility Patch", second time with it, boot forcing cache rebuild and made a PRAM reset but it didn't help. Hardware is OK, because if I boot MacPro Mojave that I hold in another partition, sound works normally.
This is Mojave sound preference pane (and I'm pretty sure it was the same with Catalina 19H15):

and this is Catalina 19H11217 sound preference pane:

Thank you very much to all!!

Onyx/Maintenance will provide clean-up. What is ironic, if one reads and follows the excellent built-in instructions within the CatalinaOTAswufix.app the bulk of updates confusion will go away. 🧐

Another update successful w/CatalinaOTAswufix.app, OC, Catalina Patcher v.1.4.4. This build seems solid, so far. 😎

MacPro 3,1 security update 10.15.7 (19H1321) all work without problem with OCLP...

I'm not sure what you mean with this... should I creare a new USB stick with OCLP instead using DosDude1's patcher? I found lot of information on OCLP, but also very confusing. And in may place I found the suggestion OCLP is for BigSur o later macOSs, and to use DosDude1's patcher for Catalina.

This has been already discussed here a few posts back. OCLP is just used as a substitute for the @jackluke provided OpenCore based tool mentioned on the first post in the Update section at the top of the page.

Do not go this route unless you understand what these tools are doing in detail. OCLP is not a Catalina Patcher.

Ok, but have you some suggestion how I could restore audio capacity of my MacPro?

Apply patches again and force the cache rebuild - as always. If this fails, re-install Catalina latest (your data will be kept) and apply all OTA upgrades and finally patch and force cache rebuild.

This is soooo obvious that I really hesitate to post this

Even better:

I thought all the time you were talking about another older Mac. 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.

OCLP is Open Core Legacy Patcher. It’s a different method from the dosdude1 patcher to get macOS on unsupported machines.

I know that it can be overwhelming seeing the 575 pages in this thread, but when you have some free time, I would recommend that you try to thumb through, and start reading as much of this thread as you can from the beginning. If this is a new interest for you, it would be a good idea to skim through this thread from the beginning and also the “Big Sur on unsupported macs” thread as well. A thread for the upcoming 2021 release of macOS (macOS Monterey) was also started recently.

These websites also have a lot of good information:

for legacy macs
https://dortania.github.io/OpenCore-Legacy-Patcher/

For hackintosh
https://dortania.github.io/OpenCore-Install-Guide/

It’s quite a lot of reading, but many of your questions will be answered by studying the macrumors threads(from the beginning) and the websites above. You will be able to learn a lot about what is possible and what is not possible with your old Mac, and you will see how others have troubleshot problems and overcame them. The solutions already discovered and documented by these websites and threads will be applicable to many of the situations that you may face yourself. Good luck and have fun with it!

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
