I'm currently waiting on @dosdude1 for the installer patch. We'll see how long it is before that's finished. I will update the main post and probably post a little announcement. I look forward to you using macOS Patcher (and thx for the follow)!

Thank you appreciate it! I look forward to it as well, thanks for being so helpful and responsive! No problem!

Sorry for the late answer,
So, I tried the single user mode trick, doesn't do anything, I installed the IOSurface.kext (and the other one from the .zip as well), and now it's stuck at the end of the loading bar, will try to boot in verbose to see.
On the iMac side, i now have sound working (AppleHDA.kext from HS installer) and wifi (from Mojave partition), just needing the graphics acceleration and it's good to go.
I'm sorry, I'm not really experienced in things like this, I always used patchers and I never install kext, even if I use patched Macs everyday.
[doublepost=1560620237][/doublepost]Stuck at this, idk what it means, it may be useful for you ?

As already wrote "apfs_spec_read_wrapper" are not severe messages, but you need to rebuild a kextcache with those kext you replaced, but first you can try to boot this way:

Enter in a Recovery or USB Installer Mojave, open Terminal and type:

csrutil disable

nvram boot-args="-no_compat_check -x -v"

reboot

edit:

These are manual methods that I use to rebuild kextcache and fix kext permissions: chown/chmod/kextcache from single user mode or booted system

unfortunately from Catalina you can't rebuild more kextcache from its single user mode.

QEMU fans, may have found something of interest.

In macOS Mojave and Catalina there is a file called 'AppleQEMUGuestAgent'

It it located in

/usr/libexec/

it's man page doesn't tell us much:

AppleQEMUGuestAgent(8) BSD System Manager's Manual AppleQEMUGuestAgent(8)

NAME

AppleQEMUGuestAgent -- implements support for QMP commands and events.

DESCRIPTION

The AppleQEMUGuestAgent daemon works only within the context of a launchd

job and should not be run from the command line.

IOHIDFamily.kext is only needed to fix the delay on Catalina booting, I guess Mac 2011 (Sandy Bridge) are not affected by this, how much it takes to boot your Catalina ? If less than a minute (on an SSD) then you don't need it.
[doublepost=1560621178][/doublepost]

These many "apfs_spec_read_wrapper" are related to 32bit coding still present on old frameworks, but they're not severe and don't compromise the Catalina working.

For which other kext/framework you may need check: here

To avoid single user mode panic you need a valid prelinkedkernel, you can copy the immutablekernel (keep a copy of it) and rename it to prelinkedkernel, but you should do that from a Recovery Terminal or another macOS HighSierra or higher.

I thought I had gotten everything I needed for the GT320m but I think I am missing things as I still don't have GPU acceleration. I think I've either missed a few kexts or is there bundles I need from the high sierra kexts folder?

Edit: I walked away and came back to see it had rebooted and now no input devices work (neither internel nor external)

I'm willing to implement a flag for that but that's all. macOS needs hardware acceleration to run at a good speed. And how far are you going with this? Do want no graphics patches at all or still framebuffer patches?
[doublepost=1560582993][/doublepost]
I also noted in the release notes this little snippet of text. "Metal is available in iOS 13 and tvOS 13 simulators when running on macOS 10.15. Metal code is executed on the host Mac GPU, and is significantly faster than simulated OpenGL code." So it seems like Xcode 11 requires Metal for at least the new OS 13 simulators and probably just crashes the whole app without it.

The graphics card I have now is absolutely incompatible with Metal. No way it can get graphics acceleration working in here. Yet, the dosdude1 patch for Mojave makes Majove work like High Sierra did, I would not call it better or worse. This is what I need, nothing more. Probably no Mac OS X had graphics acceleration on this since Yosemite. I just want to upgrade the current state to Catalina. This is me. About others, I am sure there are some people with similar preferences.

Mac Os Catalina fully working
Many thanks to!

@jackluke for his instructions
@ASentientBot for his patches of the Mac Os Frameworks

@dosdude1 @0403979 : For their effort to make a easy installer for older Mac's.
Looking forward to the new patchers.

If developers need some help let me know, I can test some things and share logs.
Photo app not working.Is already known.
Memory handling is seems better ,less memory pressure comparing to Mojave.

Good to be here on MacRumors:)

I am not so sure there are others who actively don't want graphics acceleration. If you don't have it because the OS is too new then fine but if you actually don't want it... then that's a bit strange.

Did you manage to get accelleration working?
I have an early 2011 MBP, could you share your detailed procedure to install? thanks

They are outside the InstallESD.dmg , I mean they are here /Install macOS 10.15 Beta.app/Contents/SharedSupport/

but I guess you could download them separately, keep in mind that Catalina BaseSystem.dmg is about 500 MB.

The little advantage is that inside the Catalina BaseSystem.dmg you will find the "Install macOS 10.15 Beta.app" forked of the rest, but you can create a full installer from there adding manually a "SharedSupport" folder.

You could retrieve from sucatalog there should be URLs I guess, but don't know exactly how to.
Click to expand...

Would you be able to expand a bit on that?
So I do have BaseSystem.dmg and InstallESD.dmg(6.5GB altogether).

I'd highly advise just using my macOS Downloader tool to get the full installer app straight from Apple.
Click to expand...
Or macOS Downloader. Link in my signature. They both do the same thing. GUI or CLI.

Edit: I personally prefer CLIs for these types of things. But most people like a nice GUI. I often mod little apps like this and change the icons lol.
