Where is the 3.0 download? I can not find it on GitHub, only a zip with the name master. I have got an error saying the Catalina installer is not supported.
[doublepost=1564160802][/doublepost]
This machine is a legacy one, it does not have UEFI. Using the unpatched Catalina on the pen drive, if I use the standard Clover I got an error at boot that this machine is unsupported. If I use the Tonymacx86 Clover version, based on a earlier Clover (Early June) I manage to boot up to the installer, but both internal hard drives, one having an APFS partition on it (Mojave runs on it, SATA), the other a HFS+ one (ATA), are invisible to the Catalina installer.

The Mojave patch worked very well. The Catalina patch seems pretty different in conception. Anyway, there are people, not just me, who use it in Hackintoshes, to avoid unneccesary hardware upgrades. The purpose of the patches, as I see it, is to make macOS run on unsupported hardware and avoid unnecessary hardware upgrades, regarding that is about an official or a Hackintosh.

If you're on a non-Metal system, I would strongly advise you to stay on Mojave unless you absolutely need Cat for some reason. The graphics patches for 10.15 are too unstable for daily use.

This has been confusing to me... is the graphics issue likely to improve or is it not fixable?
Click to expand...
An improved fix would likely require somehow re-adding the OpenGL fallback into the 10.15 frameworks and/or emulating Metal with OpenGL calls, either of which would be very challenging. I don't have the skills to implement either currently; not sure if @pkouame or others are still working on it. I do not recommend ever using my patches on your primary system.

How come? I do not need graphics acceleration, anyway.

You're insane. But you're right, Cat with no acceleration vs. Mojave with no acceleration should be roughly the same (terrible) experience.

If the graphics on Catalina are the same as they were on Mojave, with no graphics acceleration, it would be fine for me. Yep, I am insane, I know it and proud of it. ;)

I can not seem to understand the source of the issue. What changed in the Catalina patch since the Mojave patch so much?
I would try the patcher made by 0403979 but what I have downloaded from his GitHub I do not understand at all.
The installer boots from the unpatched Catalina, as it did on Mojave. If it supported Mojave with patches, Catalina should work in a similar way.

Are you sure the problem isn't with lilu or whatevergreen or something like that. I have my hackintosh working great with mojave, doing version upgrades without problem but can't make it boot in Catalina installer be it USB or install from the appstore file. Maybe Clover needs to be updated?

It’s not a “primary system” but If it’s unlikely to ever work, I may go back to Mojave.

Is it possible to bring the Mojave versions on the affected apps to Catalina?

As I said, standard Clover, the latest version, does not automatically select the system definitions correctly. The Tonymacx86 does it, but the Catalina installer does not see the internal hard-drives. In both cases, the Catalina installer is un-patched, the patched one does not even start booting. I suspect the Clover developers do not test it using the Catalina installer patched with the dosdude1 patch, but the rest of the issues should be available to them.

I am just curious why do you need Catalina? Does it have a better security? I was actually using Leopard 10.5.8 for absolutely everything until August 2018 without any issues. The same goes for Windows XP(without POS updates).

Better security and app supported, even for those that do not require metal. Besides, if a macOS version is succeeded by another macOS version that has the same system requirements, it is pretty clear that the first needs to dumped and replaced with the second, since the first shall not receive any real security and performance updates, since, according to the Apple logic, the next macOS is the security and stability update of the old one. Only a macOS version that is the end of the line for some older hardware can get some security and stability updates, but they are pretty unreliable, I shall say.

Keep in mind though that you aren't likely to get the microcode fixes from Intel on any unsupported Mac.

For me it’s because Apple bundles their app updates with the OS and I want the new features in Reminders, Notes, Photos, etc.

I believe it is possible but will depend on your hardware. Native APFS support is when Apple officially supports APFS on your machine.

I want to believe too.
Thanks, when time will come to move to 10.15. I'll try it out.

@0403979 Thank you, your patch, alongside Clover+FakeSMC managed to boot the Catalina installer. One issue still persists: the Catalina installer does not see the internal hard-drives, the main, SATA one, where Mojave is installed, and the slave, on ATA, that is a HFS+ partition for documents. Clover on boot sees lists them, still. This issue was present even when the Catalina installer ran un-patched.
Attached the contents of the EFI partition.
The specs are:

ASUS P5P41TED
Intel Core2Duo E8500
2 gb ram ddr3
Nvidia GeForce 6200
