macOS 10.15 Catalina on Unsupported Macs

[Starplayr]

How to uninstall Catalina properly and delete Catalina data partition? How to re-install Catalina to avoid multiplication of data partitions?

You can remove the Data container from within Disk Utility. Click on the Data container, right click and delete APFS Volume. Be sure to back up any Data from this volume incase you need it.

They are totally unrelated to any macOS functionality or light/dark mode, they are just unix "VolumeIcons" for the apple bootloader, nothing else.

Purrtie.

If you have Catalina on a dedicated drive like I do, the approach that I use is to boot under patched Mojave and from a Terminal window, use diskutil to unmount the Catalina volumes, in my case on the synthesized disk5, with...

sudo diskutil unmountDisk disk5

Then, having previously noted which physical disk (such as disk1) used by the synthetic disk5 from the output of 'diskutil list', I nuke it with gpt.

sudo gpt destroy disk1

...then recreate it with...

sudo gpt create disk1

...and finally use Disk Utility to erase disk1 again with APFS partitioning.

Also, while I haven't tried it yet, I would expect reinstalling Catalina over an existing Catalina volume shouldn't be creating an additional Data volume but just reuse the previous one.

It's not a bad idea to remove the Data Volume before hand and it's easy to remove it if it's on a secondary drive.

Has anyone tried lilu , innie and what evergreen for pci fix hdmi audio fix

On a Mac Pro with proper patches none of those are needed and I would imagine many other patched Macs with the latest developments on here do no need them either.

I am still running my own CatWoman patch set and its been working fine.

It depends because of the 4th of July holiday on Thursday, it's caused variation in the release schedule before. They might delay a week so that major bugs aren't encountered over the holiday when there might not be as many engineers available to push out a fix.

Hum... Just find an app in Catalina that seem to be related to the new Mac Pro

/System/Library/CoreServices/Expansion\ Slot\ Utility.app

The icon of the app is the new Mac Pro. There is a file with a list of old video cards from ATI, Nvidia and Intel.

It appears to be an ancient legacy program for Mac Pro (Original) and Mac Pro (8x) that Apple never pruned.

It is my opinion that because the app icon is updated, Apple is going to be using this, they just don't have it fully updated and ready for the new Mac Pro yet.
[doublepost=1561783267][/doublepost]I have no plans to purchase a new Mac Pro, at least I don't think I do. I can't imagine needing one, but its nice to think that I could have an Nvidia GPU if I wanted.

Thank you, Mr. Dosdude1. I upgraded my mac pro 5.1 (2012, 6-core, 32GB RAM) successfully. 1. installed my stock nvidia gt 120 2. booted with patched usb. 3. #csrutil disable 3. installed over mojave 4. booted into usb again, patched but NOT non metal patch. 5. installed my ATI RX 580 again. 6. Booted into Catalina. Stock Wifi is working, also my BT 4.0 usb stick. Everything is stable so far. Put into sleep over night, woke up flawlessly in the morning. Great work as always!

 

[echophilon]

Your mp 5.1 is supported by Apple and will get firmware updates as required with Mojave. I believe the latest is 14.0.0.0.0.

Hello, the latest firmware for Mac Pro is
Boot ROM Version: 144.0.0.0.0
Cheers

Nice to be able to use the RX580. Keep an eye on the next Mojave update in case it contains firmware for the mp5.1. You may also want to try Catalina without the patches - mp5.1 seems to work fine without them. Just the
sudo nvram boot-args="-no_compat_check" seems to be enough.

Thanks. AFAIK, it only works if you have done the upgrade on a supported mac and transfer the already upgraded disk to the unsupported(?). BTW, I asked myself why the weakest mac mini 2012 is supported but not the 10 times stronger Mac Pro 2012. My hypothesis is that's because the 2012 mac pro is technically almost the same as the 2010. And all Macs from 2010 are not officially supported. Cheers

@ASentientBot, FYI also on a supported Catalina Mac, renaming temporary the MTLDriver.kext to kext2, hence disabling the Metal acceleration, Photos.app crashes exactly the same way as using yours Catalina non-metal-OpenGL-fallback patches, so, even if it won't work properly, but what you think about releasing a "PhotosUICore non-metal" as a beta pre-patch?

Or do you think that in later Catalina beta apple may release a Photos.app with a CoreImage fallback, as they did for Xcode 11 beta 2 ?

 

[DragenFi]

During some my test using "createinstallmedia" to create my custom Catalina Installer, I noticed that the official apple Installer from beta2 used an icon on its Catalina Installer USB/Partition, then since it's a standard apple icns, I've applied it also to my Catalina main Volume, here is an automated script for it, totally harmless and safe for your machines.

To check the new Catalina icon on your boot Volume, after the reboot or power-on, hold (as usually) "alt-option" key for the apple boot manager. Try it, it's funny.

Morning jackluke, Do you have the dark and light icons of Mojave and a script that would allow me to use them on my Mojave install or what to change in the script included in your post?
I’m holding off making the leap to Catalina for a little while so thought it would be nice to have the icons while I still can appreciate them.

 

[pippox0]

The answer is more simple : apple: "If you want the new OS , you need to sell your old mac and buy new one"
It's a matter of business

 

[eurasian]

Any solution? Please....

For mine I've created custom icons starting from png (transparent) files, but I guess they are present in any apple official full "macOS installer.app", however let me check.

In the script you just need to change the .icns files used.

FYI apple proprietary icns use 10 pictures, and it is the 6th icon in the left tab the one used for the boot manager.

Give me a while, since can't find a full Mojave installer, for full I mean the apple official one, not the patched one.

I found them inside my full "Install macOS 10.14.3.app", let me test if they work and I'll upload here.

Apparently they don't worked, so creating my custom icns in my case has been effective, seems there is some apple signature check.

So later I'll provide you the working Mojave icns for apple boot loader, these ones uploaded are the apple Mojave stock ones and won't work as VolumeIcons for the apple boot manager.

You may have looked at this already but here is a link that may be of interest:

There is a thought that the mp5.1 was going to have Catalina support. But this was withdrawn at a late stage due to the intel cpu security problems. This is probably why it can run Catalina with very few changes needed.

Provided you have set the nvram (say from your Mojave drive) then installing Catalina using the usb installer but not patching should work. This will give you Catalina in its original form which is the way to go if you can manage it. I am tempted to get a 5.1 if I see one at a good price. However my 3.1 is not doing so bad for an 11 year old machine. All the best.

Where are those downloaded from and how do i apply those patches ?

 

[jackluke]

@DragenFi here is a script I wrote for easily applying the Mojave day/night Volume icon for apple startup manager, I also included the possibility to return to the default volume icon.

The script is totally safe and harmless for any machine.

While the apple stock "Mojave icns" didn't worked (previously uploaded), instead these icons that I manually modified/patched will work properly as VolumeIcons.

 

[macinfo]

@jackluke do you have Catalina running on a HFS+ volume, as the catwoman icon name in your boot selection screenshot suggests?

Anyhow, I think I’ll finally let the APFS ROM patcher do it’s magic on my MacBookPro4,1.

The catwoman icon (I've edited a bit cause wasn't transparent) is taken from @Starplayr 's https://www.starplayrx.com:8181

Yes, got Catalina working on HFS+ thanks to @toru173 and @crazybirdy this post for reference : Catalina on HFS+ - a HOWTO

 

[macinfo]

Thanks @jackluke, that is good to know that it’s still possible to be installed on HFS+, especially for those who can’t patch their Firmware.

2010 wasn't officially supposed in Mojave either, but users can upgrade its firmware to be a Mac Pro 5,1 instead of a 4,1 but you are exactly right they are technically the same machine hardware wise.

Apple killed the 2012 Mac Pro because of 1 reason, they released the 2019 Mac Pro. Plus I don't think the 2012 Mac Pro has Thunderbolt but the 2012 Mac Mini does. So they may have drawn a line in the sand and are only supporting the Mac Pro's with Thunderbolt. So that includes the trash can 2013 Mac Pro and the new cheese grater 2019 Mac Pro.

I think Apple decided at the last minute to stop its support.

The Mac Pro should have went back to pricing that users can afford like in the old QuickSilver days. where it was like 2499, 2799, 2999. 5999 for a bear bones model is crazy.

Then if you want the monitor that's $4999 then the stand $999 the Vesa mount $299 and the power cord$199

I didn't know the Power cord was extra. That whole monitor thing is like selling a car without wheels, doors and seats.

I love my 4K ASUS display. I run it at:

Resolution: 5120 x 2880 (5K/UHD+ - Ultra High Definition Plus)
UI Looks like: 2560 x 1440 @ 60 Hz

It's not really 5K, but that res at 4k still looks decent.
