macOS 10.15 Catalina on Unsupported Macs

[redheeler]

"macOS Catalina will be available this fall as a free software update for Macs introduced in mid-2012 or later" https://www.apple.com/newsroom/2019/06/apple-previews-macos-catalina/

So this also means the Mid 2012 Mac Pro (and by extension the 2010) are safe presumably. Same requirements as Mojave.

Oh dear. We might have a big problem here. "macOS Catalina runs in its own read-only volume, so it’s separate from all other data on your Mac, and nothing can accidentally overwrite your system files." https://www.apple.com/macos/catalina-preview/

That's not good. But I'm sure there will be a workaround with System Integrity Protection disabled.

This looks like some kind of Docker-like technology, or something akin squashfs.

I hope so. If not then we don't really have a chance. Here's hoping a plain package install will at least work.

Download a copy of 10.15, straight from Apple.

Mac Pro 5,1 has been dropped, ladies and gentlemen...

It'll come later, just like with 10.14. They just haven't implemented the Metal GPU detection yet.

How time flies, seems yesterday I installed Mojave.

If someone had asked me to pronounce 100 names for 10.15 I'd never guessed Catalina.

its your patcher compatible? to test it 🙂

Do you have any indication to that? Apple didn't post the Release Notes...

Thanks, I know there is a process to do this manually but I already forgot what it is.

That icon really looks like a cheese grater. The resemblance is unreal.

When Apple heard us chanting "bring back the cheese grater," they must've taken that literally.

how big would the chance be that mojave patcher patches work on beta1 lol

I guess not this time. My goal is to get it running as soon as I can and I could certainly use the help of people more or even less experienced than me. And thanks to @dosdude1 and @Larsvonhier, I now have my own MacBook4,1 to use for testing unsupported macOS on. As I'm currently the only developer who is developing a patcher tool that supports the MacBook4,1, this is very useful for me. Thanks a lot to both of them.

I would love to join you on this endeavor. I used to work on the patches on MacPostFactor and macOS Extractor but then have the time to because I was finishing college.

Curious did they say that? Cuz it reads like the final version won’t run on 5,1s on the website.

Hey again everybody!!

Software catalog is up: InstallESD is about 30% downloaded for me. Can't wait to get this running 🙂

This is quite interesting.

I'm so happy to see you on this. I'm actually planning on making a new patcher for older versions (10.8-10.11) called OS X Patcher. This patcher will be based on the amazing work by you and the rest of OS X Hackers, and built from the code base of macOS Patcher. If you're willing to, your collaboration would be greatly appreciated.

More patchers is never a bad thing, but do you guys want to make a shared GitHub repo or similar listing how each patch works this time around? Rather than having 3 competing black-box tools.

Just a thought. I'll be posting any of my findings publicly as usual and I hope everybody does the same.

6 minutes remaining on my download! Let's do this!! 😀

Do you'll install it on HFS+ or APFS ?

Meanwhile finger crossed for Penryn Core2Duo and non-metal acceleration.

@TMRJIJ's read-only volume quote makes it look like APFS might be mandatory. I'll give HFS+ a try, though.

I'm planning on documenting how macOS Patcher works. I think using a bash script and simple Apple scripts for the Patch Integrity Protection GUI, allows somewhat experienced users to more easily understand how macOS Patcher works. I would like to document all of this as I have a vast knowledge base from browsing threads and reversing engineering other patchers but unfortunately I don't currently have the time. Luckily, summer holidays are in a month so I should have plenty of time away from school to work on macOS Patcher, OS X Patcher, and associated documentation to come. It's also a question of priority. I'd rather work on creating the tool, than documenting it. But as I said, once I have more time then I can catch up on that.

I think I'm the only one with any interest in a retro patcher like that. But I recently got a MacBook4,1, courtesy of @dosdude1, and @Larsvonhier so that will be a big asset in this venture. I've currently reversed engineered MacPostFactor and attempted to package it into a bash but I haven't tested anything yet. Of course it's much easier having one of the actual developers to help me with it than trying to understand a pre built app 😉

I don't know if that's the case or not. Does APFS run on Traditional Hard Drives? If the non-retina 2012 Macbook Pro is still supported with those HDDs then it properly won't bother us as much.
