Hello everyone. I have unsupported Imac 27, 2011 with AMD Radeon HD 6770M 512 MB and 24GB DDR3. I know that this is old mac but i like to use it. Is it worth to install Catalina on this mac? I know not everything is supported. I using this mostly for Pages, Office, Youtube, simple apps for photos. Greetings!
Check the very first post of this thread and/or the official documentation on the (dosdude1) download page:
No support for your system and in particular your GPU on Mojave or Catalina using the dosdude1 patcher.
But you may try using OCLP, Mojave and Catalina with Version up to 0.4.1 (check the release notes, at some point Mojave/Catalina patching was dropped) and Big Sur and Monterey using the latest version, which is 0.4.11 at the time of writing this message.
Edit:
And you can change your GPU to make your system fully supported with all macOS versions including Monterey…(the the link in my signature).

Oh, i got this, but after installing Mojave system says - 14 mib unknown video card
Most likely you need to apply the patches after primary installation. Take a look into the OLCP online documentation, the process is always the same, regardless which macOS version you install.
And it would help if you reveal some more information about your hardware.
Does it mean that I have to install it via dosdude installer(but not works for me, I’m using another solution) and then patch it with oclp by post install patching?
No, you cannot install using @dosdude and patching using OCLP or vice versa.
Using Mojave this should work OOB following the (or the OCLP online) guide I created two years back on the MR thread. Use moderate spoofing during installation, change to minimal spoofing afterwards.
But you have likely flashed a wrong vBIOS on your S1700X. This is the root cause for such 14MB error message.
The S7100X does not allow your particular iMac to sleep/wake and may cause additional problems needing a PRAM reset on each reboot.
Do you have the original vBIOS which came with the card. Move to the thread found in my signature. This is unlikely Catalina related.

I am using patched MacOS Catalina on my MacBook Pro 2011 17 inch with GPU disabled by software method (nvram command).
Everything feels ok, except slow boot. I was thinking that problem was in forcing trim on non-apple ssd, but when i have disabled it - nothing changed. Loading takes like 2 minutes from 240Gb SSD.
Anyway i have another question, patcher update gives me ability to install Legacy Video Card Patch. Is it safe to install that patch if i have a dead radeon gpu

Once i sorted my own GPU and audio issues, Catalina is working as solidly as Mojave for me (ive got a dual boot for testing and comparison) The *only* problem is not being able to use the Music (formerly itunes) app in Catalina...are there any workarounds for this?
My recommendation, since theres not much activity here, is to reinstall the OS again, and avoid the legacy patcher..tbh it was the source of a few problems for me. my safari is fine.
Do you have a metal GPU? In this case I would strongly recommend to use OpenCore to run Catalina and later on your system.
There are several methods available and documented here on several threads especially for MacPro5,1 systems to install it and have Catalina unpatched.
OLCP has dropped Catalina and Mojave support with version 0.4.4. Of course you can download and use an older version to enable root patching and technically there is no reason to use the latest OCLP version with Mojave or Catalina.
@grooveq @Ausdauersportler I have Geforce 330M (pre-metal)
I was able to solve this problem - I dont know how, but i was able to install latest legacy patch (I think it was released around week ago).
I dont have any other problems - Only one with video playback in safari. Usually I have black "window" when I try to play video on youtube or facebook. I have to force QUIT safari and open it again :/ Maybe somebody know about fix for this - I have this issue since I updated OSX to Catalina.
Thanks

I have another issue, more than just a slow boot.
I have installed and trying to use Photoshop 23.5.0 on Mac OS Catalina patched on my MacBook Pro 2011 17 inch with failed amd graphics.
I can't use most of the tools in photoshop, cause in setting it shows "unknown gpu".
Is there any way to fix that? Or what version of PS i should use.

Use a version from 2020 or before. In summer 2020 High Sierra lost support and so your MacBookPro. Later versions obviously need a more recent GPU (with metal support?). Same rule of thumb applies to all GPU centric software products. Here the idea of patching finds it‘s limitations. If you need more modern software and tools you need to upgrade the hardware.
Yes while mostly everything works, and i certainly know what to do if my GPU gets blocked, I am thinking I might in fact be best to go OCLP and Big Sur. Might as well move up another OS, judging by what's working in Catalina. Im planning on doing an OC / Big Sur fresh install and migrating the current 'dosdude catalina' drive Apps/etc into it (- I have it backed up on another external SSD - should this work?) as I've spent quite a while cleaning out the 32bit crap (I'm keep mojave on my other boot drive for the few things id like to keep access to)
You mean from appearing on the desktop and prompting to update? System Preferences>Patch Updater>uncheck the box "Check for updates automatically".
Q: I 'installed' the Catalina patch on a Mac mini 5,1. It went through the whole thing without any issues but when it rebooted I went straight back into High Sierra as if nothing had changed. Do I need to have a fiddle with any OSX settings before I can get it to run? I had heard about some 'root' settings introduced in El Capitan that prevents OSX from running unauthorised code.
Just curious (and not sure whether this is has anything to do with your issue): Dosdude states on his page, "Macmini5,x (systems with AMD Radeon HD 6xxx series GPUs will be almost unusable when running Catalina.)" Had you read that before trying to install Catalina on your machine?
I have an intel gma chipset. No AMD. It’s just that it ran the installation process, didn’t spit back an error but then didn’t install anything!
