macOS 10.15 Catalina on Unsupported Macs

I have this same thing on one of my iMac12,2 systems. Tried putting the patcher on an internal partition, same thing. Patcher works fine on my MacBookPro8,2 so it's not an installer issue. Very odd.
Quick question: I have an iMac 11,1 (late 2009, 27, i7, upgraded Airport-Module) running Mojave 10.14.6 with the dosdude patcher.
Interestingly Apple Software Updater shows me Catalina-Upgrade option?!?
Question:
1) Does the dosdude patcher pretend to be a fully eligible mac and therefore software updater shows Catalina?
2) I guess it’s still not a clever idea to update via the official apple softwareupdater as it will probably fail?

Hi! I've encountered a problem which I'm not sure whether is hardware or software related. The thing is — my display port (thunderbolt) doesn't work anymore. My machine is a 2011 MacBook Pro 13. Before updating to Catalina (was on patched Mojave) my dongle (thunderbolt to HDMI) worked without any drawbacks.
But now I simply cannot use my external monitor. My screen goes black for a half a second I connect my cable and then goes back without any additional things happening. Dongle works as it is — I confirmed that by plugging it to another Mac. So either it's a hardware problem or something is up with Catalina.
Any suggestions?

I had no problems on my MacBookPro5,3 with Beta 9, but I installed the full release yesterday and had a ton of issues. I haven't had time to investigate them yet, but some of them that I remember were:
- I couldn't get BlueSky to work
- Chrome wouldn't launch
- Trying to delete anything from trash would cause an error
- When I would open the zip file to reinstall BlueSky, it would tell me that this file can harm my computer and force me to either delete it or cancel opening
There were other issues too, but I'm going to try reinstalling it again and see if I can be more specific with my issues. I'm going to erase the drive this time before installing, instead of it just updating, and hopefully that will fix some of the issues as well.

@dosdude1 : the "Install to this machine" is n o t working on my MBP4,1, on restart the machine does not boot into the patched installer, but starts up into the old DP8. Creating the ISO did n o t work as well.
What can I do? Could you maybe advise, how the Terminal workaround is done? I tried several times to follow your instructions earlier in this thread, but they confuse me. Please excuse, I'm not an expert at all with terminal hacks. Your help here would be highly appreciated!
Also check dosdude1 macOS Catalina Patcher on the first page of this thread a new version is our 1.1.7
Hi @ASentientBot, I was reinstalled 10.15 DP8 and result same problem in Japanese IM.
Is it foreseeable that Software Update will work in macOS Catalina, if installed thanks to dosdude1's patcher on an unsupported Mac, any time soon?
After the patcher is finished creating a boot disk, I go to Preferences and select startup drive and select my newly made catalina installer disk, then select restart. The machine restarts to the Catalina installer drive and I get the utility screen where I select reinstall and it will ask where I want to install it. I select my second SSD and it attempts to install but that’s where I get the error message... the easy way to get back to my original boot drive (my first ssd), is to shut the machine down, then remove the Catalina installer drive. Then restart the machine and it will fall back to my original Mojave install. From what I’m reading here, I can’t use an external memory stick as the installer drive so later today I’ll try using a internal disk as the Catalina installer. My objective is to leave my Mojave drive untouched. If this is your objective as well, be very careful. As much as everyone here wants to help, some advise I’ve received are guesses, not proven facts. I don’t have the time to rebuild what’s already working so I’m not going to risk anything that puts my workflow at risk... I’ll let you know how it goes for me. Still don’t understand why I maters if it’s and internal drive or an external memory stick but I’ll give it a try as long as I’m not putting my overall matching at risk. Lastly, sorry if there are typos... using my iPhone and don’t have my glasses...

Another successful Catalina upgrade to report - MP3,1, RX570 GPU, TRIM via "sudo trimforce enable". Upgraded from Catalina DP7 to Final using @dosdude1's patcher v1.1.6.
Also - if you have a relatively modern video card (with GOP support) but no Mac-EFI BIOS available to flash: @Ludacrisvp posted a great tip here on how to get boot screens using rEFInd. A quick recap (all credit goes to him, see his original post for details):

- Find your EFI partition using "diskutil list", mount it to /Volumes/EFI
- Download rEFInd from here, unzip it into /Volumes/EFI/EFI (which will create a refind subdirectory)
- Download OsxAptioFix2Drv-64.efi from here, place it into /Volumes/EFI/EFI/refind/drivers_x64
- Make rEFInd bootable using the "bless" command: sudo bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/refind/REFIND.efi --shortform
As of now not yet

do you have a downloaded install macOS Catalina in your downloads folder
[automerge]1570641326[/automerge]
Are you using the latest version of the Catalina Patcher also try seeing you can get into the desktop without applying the post install patches I know a few times I got distracted or forgot to install them and was successful getting into my desktop

YES and YES. Downloaded dosdude1's patcher tool v.1.1.7, extracted it from the dmg. Downloaded a copy of Catalina through the patcher, proceeded immediately to "Install to this machine", created patched install into /tmp with success, the patcher then brought the Catalina installer to the front, said Yes to Apple license agreement, estimated time for installation about 13mins. ... Restart, 20secs I got a grey screen (my guess: installation is looking for the patched installer in /tmp), then Apple logo, voilà my MBP4,1 is at the login screen for unaltered DP8. What can I do?
No issues here! Straight after install everything was very slow and laggy, but after leaving it a few hours it settled down and I haven't had an issue since.
Thats exact the same problem I have with my Mac mini 3,1. @dosdude1 do You have an idea?
Having very similar issue with my MP 4,1 (flashed 5,1). One commenter suggested it was my old BootROM (MP51.007F.B03) but I can't figure out how to update that at all.
Note that for reasons unknown this only appears to be usable for the 3,1... the 5,1 doesn't seem to load it, and nobody that has an un-flashed 4,1 has tried it either.
yes the Photos App works partially it calls for Metal instruction code for all Photo's tab to display which our old CPU's do not support
Go here for instructions

@Howard Ellacott Hi. Looks like we have the same GPU, and I am having issues with my machine, trying to watch videos and getting high CPU usage.
Can you please re-test and confirm if hardware acceleration is working fine on your system? Thank you very much for your time and attention.
