macOS 10.15 Catalina on Unsupported Macs

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
So I finally got it working on my cMP 4.1>5.1 with an original GT120.

I’ve used dosdude1 patcher b6 and DP2. Everything installed at first attempt (on a SSD formatted as Macos Journaled/GUID).

I also managed to patch Nvidia web driver with the build number and now my GTX 1070 is working (No acceleration).

Bluetooth and sound are working. WiFi doesn’t. I believe I’ve a 802.11ac + Bluetooth 4.0 (Broadcom BCM94360CD) lying around, if that’s the case I could check if it’s working today.

Thanks all!

The tool now only supports using the Developer Preview 2 installer app (due to some extreme changes Apple made to the DP2 installer). You can download it using my macOS Downloader tool.

Do you plan to release a Catalina PartialPatcher with a verbose output?
I mean not only a progress bar, but showing output scripts as hdiutil, asr and so on, in order to make easier to debug where exactly it throws exceptions.

I tried and got "can't save the Image" or similar message, however I found where you placed your custom BaseSystem.dmg in /tmp/ I may try to restore it on a disk partition and then manually add the expanded InstallESD.dmg packages there (on the restored partition /System/Installation/).

edit:
Tried also replacing inside /S/I/Packages/ your patched OSInstall.mpkg
but getting from GUI Installer "The installer resources were not found"

Can anyone take a note for me about what should be replaced to have a functional Catalina? My note is too messy now.

What worked for me on a MacBook5,1(Catalina Beta 1):

- removing telemetry plugin
- adding LegacyUSBInjector.kext to the /L/E - I confirm that it is sufficient, no other USB related patches are required.
- ASentientBot's fixes(CoreDisplay, SkyLight, IOSurface, IOHIDFamily)

The rest is pretty much straight from the Mojave:

IO80211Family.kext
AppleHDA.kext

AppleGVA.framework from High Sierra if you want to watch DVD's in DVD player app.

Can you use keyboard and trackpad from a booted Catalina desktop ?

Or maybe you replaced some wrong kext and since then you can't use keyboard more?

I ask because you posted a picture with "About this (Catalina) Mac" opened and you can only go there with a keyboard or trackpad working.

If so you can directly from booted Catalina Terminal copy/paste one line at once:

sudo chown -R 0:0 /S*/L*/E*/
sudo chmod -R 755 /S*/L*/E*/
sudo kextcache -i /
(this will take a while to complete)

reboot in single user mode and you should be able to use the internal keyboard.

Actually, yes, I forgot. 2010-2011 machines should have their USB working OOB.

In my machine I have Mojave (fully working no problems at all and keyboard and trackpad working great) and other partition with Catalina.
I only replaced the kexts you shared. And since then, when I try to set single user mode to fix kexts permissions, as you said before, I couldn't write anything. That was it. Can I use Mojave terminal? Just to know.

Even if I don't prefer to chown/chmod from another macOS, I guess you can from a Mojave Terminal in this way:

sudo chown -R 0:0 /Volumes/YourAPFSCatalinaLabel/S*/L*/E*/
sudo chmod -R 755 /Volumes/YourAPFSCatalinaLabel/S*/L*/E*/
sudo touch /Volumes/YourAPFSCatalinaLabel/S*/L*/E*/

Kext replacing is not only copy/paste (immediately after you need to chown/chmod the replaced kext otherwise an invalid prelinkedkernel will be generated), instead only copy/paste is a valid routine for frameworks.

I suggested this: Core2Duo panic manual remove telemetry

Thnx. I was trying that. Rebuild the kexts to not have that error.... But when I boot in single user mode, it gave me that error not let me do anything.... Can I replace kexts using kext utility, for instance?

Ah, I found the cause of the diskmanagementd issue! Apple is sure making things tricky now. Got it all patched properly, though. Tool is now updated to Beta 10.

Thanks. That allows the installation to complete on my MacPro 3,1 with the APFS ROM patch applied.

The issue of rebuilding the cached and associated prelinked kernel is still problematic though. Any chance you could add a menu item to the Catalina patched installer which would bring up a dialog for selecting a Catalina volume to force the cache rebuild on?

I guess no, I am not skilled to rebuild a Catalina prelinkedkernel from another macOS.

But you could try this, from your Mojave, open you Catalina/System/Library/Prelinkedkernels/

inside here rename the prelinkedkernel in prelinkedkernelbackup

then double-copy the immutablekernel in the same folder, rename the immutablekernel into prelinkedkernel, reboot targeting CMD+S Catalina and it should allow usb input from single user mode.

I don't know other methods, otherwise re-install Catalina. But kext replacement, it's not only copy/paste, I don't use kextutility but I guess it can't target another Volume especially with a new different kernel.
