CatalinaOTAswufix.app teamed with the DD1 Catalina Patcher v.1.4.4, booted via OCLP_030 TUI brought this 2GHz Mini3,1 to Build 19H1419, smoothly and efficiently. 🪓🪓🚧😎
What changed regarding patches etc between Mojave and Catalina? I was under the impression there werent many drastic changes in the OS.
But i'm seeing distinctly worse performance on a clean install of Catalina versus a clean install of Mojave on my 2011 Macbook Air.
I realize its not a power house and it will choke if i push it too hard, but i've been going back and forth trying to figure it out, and there is still a massive difference.

Just in case somebody here is using Catalina on a MacBook Pro Mid 2009 (MacBookPro5,2): I've just written a tutorial on how to re-enable Instant GPU Switching / GPU Switching on the fly on a MacBook Pro Mid 2009 under High Sierra and Mojave. Unfortunately, I haven't had an opportunity to test this on Catalina yet (at this point, I'm not too familiar with Catalina's rootless / read-only system partition mechanisms). But if there's anybody willing to test the steps on Catalina accordingly, any feedback would be highly appreciated!
I reinstalled dosdude1 Catalina (originally was on dosdude1 and subsequently applied OCLP post-patch) and used CatalinaOTAswufix.app to get the Security Update 2021-006. But after Restarting and going through the installation process (Apple logo with progress bar for around 10min), I was presented a login screen as normal. But the system immediately logged me out after logged in the system. After logging in the 2nd time, the system allowed me to stay in but the security update was not applied.
I tried many times and always came to the same result.
It would be much appreciated if someone can pinpoint the issue.
PS. It's for an iMac10,1 (see signature)

I upgraded my MP 5,1 to the latest Catalina showing up in the system preferences with CatalinaOTAswufix.app and now I can’t see anything. It looks like it doesn’t boot anymore into Catalina as I don’t even see login screen. I have 2 monitors / both have empty screens. Pressing keyboard buttons or moving mouse doesn’t help. Never had such problem before…
Tried SMC reset, didn’t help.

I had the same issue on my mBP 2010
(THIS IS ALOT OF WORK and I will completely understand if you can't do it.)
I ended up taking the drive out of my mBP 2010 and putting it in my cMP 5,1 and updated it there then put it back in the laptop.
Cheers
Thanks makra.
tried to set up a USB stick with OpenCoreAPFSloader3, got error 71 at "mount -t msdos /dev/disk3s1 /Volumes/EFIext" saying resource busy. Not sure what is going on, proceeded to the next step: "/private/tmp/USBOpenCoreAPFSloader3/usbopencoreapfsloader2.command". This comes up with the following text:

much appreciated if someone can help me out.
PS. a stab in the dark: Would OCLP help for this: Because I installed security 2021-005 2 days ago after booted with CLCP v025 and applied the Post-Install Volume Patch. But it was just a blur to me and I could not install the 2021-006. That's why I changed back to the dosdude1-Catalina.

The file system for OpenCore is incorrect Apple_HFS, should use instead msdos FAT32 (this check is included on main application) that's why "mount -t" failed, but it's not that your issue, because your iMac should have an APFS firmware (HighSierra supported) so the question is during OTA downloading do you relaunched CatalinaOTAswufix and applied the "OTA update fix" ?
Because this "OTA update fix" step is required to automatically whitelist the board id checking when the OTA is preparing the "macOS Installer".
Thanks Jackluke. Now I know that I don't need OpenCoreAPFSloader3.app. And I could not create a suitable partition anyway (MS-DOS, ExFAT, /DOS Master Boot etc., and also tried both creating from new or using existing partition options in the app) after tried various combinations in Disk Utility under the sun, even tried diskutil command. The OpenCoreAPFSloader always generated error 71 code. I also don't really understand the prompt in CatalinaOTAswufix.app saying I need to stop the beta downloading after 1%.. The issue is that the system did not automatically download anything anyway by clicking the Beta button, and there is no beta Catalina neither. At some stage I believe I also clicked the OTA button as well. By clicking a link in the bottom half of the Software Update pane, it showed me the Catalina Security 2021-006 Update. I then proceeded to the "Install and Restart". After rebooting, my iMac asked me the login password again before the update. Another login screen showed up after finishing the installation. But it immediately quitted after the login and ask me to login again. And the sad thing is after all this, the security update was still not applied.
Anyway, I finally gave up on these 2 apps after spending many hours and went back to OCLP and reinstalled the standard Catalina. This allowed me to successfully apply the security update. I then proceeded to apply the post-install volume patch (option-3 in OCLP).
The only issue after applying the patch is that the Displays Preference Pane no longer works. But the previous configuration remains (I have a 2nd monitor connected to the iMac).
I may come back revisiting the CatalinaOTAswufix.app if I can understand the language (jargon) under a better light.

I successfully installed Catalina on my 2011 MBP about 3/4 months ago. Today I noticed that my MBP run a littler warmer than usual so I decided to do a PRAM reset. Unfortunately when rebooting I noticed grey horizontal lines... what can I do to fix this? The computer was working well up to this point 
So far I've tried Internet Recovery but it gets stuck on the spinning globe...

that MacBook Pro has a cheap cable on the logic-motherboard that is faulty and can be easily replaced.I successfully installed Catalina on my 2011 MBP about 3/4 months ago.

im sure others will be more specific to the exact name for that cable and helpful links.
at least that is what I hope the problem is.
I know this solution might seem lame, but I just don't want you to panic!

I actually sent this MBP for repairs when it died back in 2015 due to the faulty logic board. So it doesn’t have the original logic board but a different one, hopefully a better one than the original.
I think my RX580 died during the latest Catalina security update. I tried my original graphic card and it works on High Sierra. RX580 shows black screen now only.
You should try disabling your discrete GPU as explained for example in the following blog post (there are better sources for that solution I think):
https://becomethesolution.com/blogs...-discrete-gpu-faulty-mac-os-high-sierra-10-13
You can also use OpenCore to disable the AMD GPU.
You should install Catalina using the guide in this thread. Using OpenCore does not need any patching and OC offers the means to avoid the black screen issues, too. I doubt a simple Catalina update could have killed your RX580 - but I am not good at remote HW analysis.
Sorry for the confusion - I knew MBPs from 2009 didn't support HS, but iMacs do in fact.

I am familiar with Dosdude's macOS Catalina Patcher and how to update to the latest version of 10.15.7 (19H1419). Works great on the internal SSD of my 2010 MacBook Air.
I also have a USB stick with a bootable Catalina. Also done with Dosdude's Patcher. Works fine on the initial release of 10.15.7. But after installing the security updates I am stuck on the Apple logo when I boot Catalina from the USB stick.
Does anyone know why it works fine on my internal SSD and not on the USB stick? And how to solve it?

Yes I would doubt too but the truth is it died during the latest Catalina update from 23 September. I can neither boot to High Sierra nor Catalina. If I swap GPU to original non metal I can boot into High Sierra. I checked the prices and to my surprise RX580 is now 2.5 more expensive than I bought it 3 years ago.
I don’t think I can force OpenCore on non metal GPU….
RX580 fans don’t spin at all.

My understanding is that you can boot your non-metal Mac with OpenCore. You just don’t have graphics acceleration. OpenCoreLegacyPatch (OCLP) can support non-metal macs after applying the post-install volume patch.
For OCLP, you will need to enable Catalina in option 5->7, and change SMBIOS in option 5->3 from minimal to moderate.
You may also be able to disable the faulty dGPU if you have iGPU with OCLP.
1. Download the latest OCLP TUI,
2. Open the app and go to option 5 to set Catalina support and moderate SMBIOS,
3. build OCLP by clicking option 1,
4. Install the built OCLP to a EFI on an external USB or internal HDD/SSD by clicking option 2,
5. Boot your Mac by holding the Opt key,
6. Select the OCLP icon and double click,
7. Select the stock “install macOS Catalina” (assume you have already inserted the installation USB or have one in your internal drive), (you will not lose any data over the existing dosdude1-Catalina)
8. after successfully installed the Catalina, apply the security update (it may take a few minutes to show up in system update).
9. relaunch the OCLP app and apply the post-install volume patch by clicking option 3 (Catalina support may need to be enabled first in option 5).
you will always need an OCLP EFI to boot your system on either an external USB, or an internal SSD/HDD. But you don’t need holding any keys for subsequent normal booting. The system remembers your option and selects the right ones by picking the OCLP EFI 1st then your normal macOS partition.
it may look very tedious but once you get the idea, it is actually very easy to use OCLP.
dosdude1-Catalina also support most non-metal macs except for HD5xxx & HD6xxx. That’s why I don’t install it on my iMac12,2 with HD6970 graphics card.
I am currently running stock Catalina with OCLP on a non-metal iMac10,1.

So I replaced the 2x6 to 8 pin cable with the original GPU cable 1x6 pin to 6 pin and RX580 works, boots both High Sierra and latest Catalina. I am doing 144 ROM update right now from 140. Did the power cable die, really?
So we are back in OpenCore business, too. OCLP is the most easy way to implement it, the thread I mentioned before shows the sophisticated way which allows you to gain the knowledge and understanding to adjust and fine tune. It is your pick.
I will check it thanks. So the OCLP is the easiest step to start with OpenCore? Would you suggest sticking to Catalina or upgrading to Big Sur?
This depends on the applications your are using. If the complete set is fully supported and working without any glitches on Big Sur you may move on, otherwise we can expect another year of support with Catalina, so no rush.
From all my experience without a proper reason one should not hop on the latest available software release. There are always bugs in new macOS (OS and software in general) releases and it is not always the smartest to swim ahead of the swarm.
This week I wasted two days just on getting Monteray Beta 7 installing on my little iMac test farm.
As of today with the publication of the SurPlus solution you have the chance to install Big Sur. Yesterday my answer would have been: No!
P.S.: You will need OLCP 0.3.0 latest nightly build, check the Github download page for docs and software.
