macOS 10.15 Catalina on Unsupported Macs

[eVasilis]

There is a problem trying to install 10.15.5 from a usb stick. I created the installer with patch 1.4.3, started up from the stick and half way through it asks to restart the installing application because of an error. Maybe a new patcher is required?

 

[Briana27]

Yes!! Successfully patched the latest Zoom version to work under Mojave or Catalina with a non-Metal GPU!

EDIT: To apply this patch to your own Zoom install, download the attached script (zoomnonmetal.sh.zip), extract it, and run it as follows using Terminal:

chmod +x /path/to/zoomnonmetal.sh
/path/to/zoomnonmetal.sh

Yay! I'm so happy about this

Experienced the same error at 4 minutes remaining. Gave it three tries. The good news is the target partition seems untouched and runs fine. The TMP file must have been written because it took a long time to reboot after the failed install.

Are you supposed to just be able to run aut-updates for the patches now? It keeps nagging me, but I'm afraid to update.

Successfully installed macOS Catalina 10.15.5 using the swupatch-Catalinaswuamfifix5.patch-OpenCoreAPFSloader then applying the post install patches

So I assume you are trying to directly launch the installer rather than create a patched installer with Catalina Patcher 1.4.3?

No. This is a patched installer with 1.4.3.

It also isn’t working to “install to this machine”. It just keeps rebooting to the OS and never actually starts installing.

Anyone getting the following from their antivirus when Patch Updater polls every 2 hours?

Malicious traffic detected: 'C2/Generic-A' at '/System/Applications/Utilities/Patch Updater.app/Contents/MacOS/Patch Updater' This application was detected connecting to a known bad website.

Most likely a false positive.

Thank you so much for confirming my experiences. I can now sit back and wait for a resolution without fruitlessly trying different approaches.

These are the patches I used to install 10.15.5 if you have a small usb about 512mb usb make a usbOpenCoreAPFSLoader or jackluke has instructions posted some pages back to install it on the same usb as the Catalina Patcher. After making a usbOpenCoreAPFSloader unzip the swupatch and place in the terminal follow the on screen instructions then start downloading the update when the update is nearly finished unzip the catalinaswufix5amfi.command and place in the terminal run it and follow on screen instructions. After the Mac restarts you will see the black screen and Apple logo with a progress bar when it reboots hold your option button boot into the usbOpenCoreAPFSloader in the menu screen use your arrow key to choose macOS install it will then reboot and install the update thence it reboots boot into the Catalina Patcher apply the post install patch

According to the Catalina patcher FAQ - "During installation, the installer reports that "An error occurred during installation", and mentions running diagnostics (in this case it directs to try again) This occurs when the copy of the macOS Catalina Installer app used has gotten corrupted somehow. To rectify this, use Catalina Patcher to download a fresh copy of the Catalina installer, then re-create an installer volume and/or retry the installation." Patcher 1.3.4 was used to d/l the installer from Apple. Second USB installer build, same result. Nada.

I have just heard that the 10.15.5 update has been released, currently on 10.15.4. In the past to update my install of Catalina I downloaded the full installer and updated that way. Is there now a way where I can just update either through the Software Update mechanism or by downloading the standalone update from Apple Support Downloads.
Or is it still necessary to go through the drudgery of downloading the full installer and making another bootable USB.

Any help gratefully received.

On a MacPro 3,1 I tried my usual way to upgrade from 10.15.4 to 10.15.5 using Dosdude's patcher 1.4.3 via a USB external DD but

Experienced the same error at 4 minutes remaining. Gave it three tries. The good news is the target partition seems untouched and runs fine. The TMP file must have been written because it took a long time to reboot after the failed install.

Exactly the same error at 4 minutes left on a MacPro 3,1 on which I never had problems from 10.15 to 10.15.4 via a USB external DD. It looks we may need a new patcher ????????

my post 10,997 is how I did it through the software update in system preferences

You mean post 10,957 yeah I've had a look at that and may give it a go.
Would also like to know if there is a method for installing the standalone delta or combo updates.

I'll wait @dosdude1 updated patcher 1.4.4. Actually my Macmini 2010 (macmini4,1) works fine with Catalina 10.15.4

So right now, the issues I'm having are:

• Unlock with Apple Watch
• Safari Extensions
• No Airdrop from MB to/from iPhone/iPad

Can anyone that updated to 10.15.5 confirm if Safari Extension works or not?
Is there any hardware update I can do to my 2010 MBP 6,2 to allow Airdrop and unlocking with an Apple Watch?

Thanks

To AirDrop on certain machines you could use a patched Wifi driver for Broadcom cards: https://forums.macrumors.com/threads/macos-10-15-catalina-on-unsupported-macs.2183772/post-27891116

After you should enable continuity through a script, then you should buy and plug to the mac a Bluetooth 4.0 USB dongle that is required from Catalina to use AirDrop with ios devices and any other continuity feature, unlock with apple watch should work also with an usb bluetooth 4.0 dongle.

Thanks for uploading the framework file, but I haven't been able to get it to work. I moved the existing /System/Library/PrivateFrameworks/AppleGVA.framework/Versions/A to A.old and then copied in the A directory from what you uploaded, and rebooted. But I still get the following from the VDA Decoder Checker after rebuilding it:

jack@Jacks-MBP VDADecoderCheck % ./VDADecoderChecker
VDADecoderCreate failed. err: -12473
An error was returned by the decoder layer. This may happen for example because of bitstream/data errors during a decode operation. This error may also be returned from VDADecoderCreate when hardware decoder resources are available on the system but currently in use by another process.
VDADecoderCreate failed. err: -12473

There still doesn't appear to be any hardware acceleration in Firefox or Quicktime: only VLC works (as it did before replacing this framework).

Also, I'm now unable to remove the older version of the framework: I get a Read-only filesystem error when trying to rm -r it.

Edit: I've fixed the read only issue by re-mounting the system volume as rw: sudo mount -uw /.

Catalina for unsupported "non-metal" mac is not 100% graphics accelerated (as non-metal Mojave is), so you can't use a VDADecoder patch (example the AppleGVA.framework) to increase the frame per seconds during video rendering.

I'm excited for 10.16 too, but my crappy graphics patches are not going to cut it. (@pkouame and @oliveira131 both had some promising ideas, but they seem to have disappeared. I've been playing with some stuff too, but it's a bit above my pay grade. Hopefully we can figure something out by June!)

We (and the Hackintosh folks) don't have to worry about A13 Macs for a while, since Apple is bound to support recent Intel machines like the 2019 Mac Pro for several more years. I do look forward to seeing what they do with ARM-based MacBooks though -- maybe an improved revival of the unsuccessful 12" MacBook?

Probably mac ARMs are useful only to block skilled hackers like you, improving T2 chip control

Thank you, but I prefer to wait. And maybe this time I'll try to install directly on SSD, instead of creating the USB installer, as always done before.

Agreed. Sophos kept flagging this for me also, so I made an exception of it.

Thank you.
Update done on my iMac 12,1.
Since I am already using OpenCore (for my Quadro K2100m), I skipped the steps involving the USBOpenCoreAPFSLoader.
So steps at per what you mentioned:

1- Run swupatch.su
2- Launch Software Update in System Preferences
3- Through the download, run catalinaswufix5amfi.command
4- First reboot, pick macOS Install in the OpenCore boot picker and let the install run.
5- When finish, reboot to the Catalina Patched Install version 10.4.3 and apply the patches.
6- Final reboot.

Hi there,

Back here after several months, I've tried to understand something about CatalinaOTAswufix, USBOpenCoreAPFSloader2... but I don't understand anything It seems to let me be able to make a classic software update instead of create a new bootable 10.15.5 USB drive using Catalina Patcher ? (I just managed to show that there is an update available in the system preferences. But I have too few multiple reboots to do with everything I did not understand ...)

Well, too complicated for me.

So, my MP5.1 is running Catalina 15.3. Do you confirm that simply create a bootable 10.15.5 USB drive using Catalina Patcher 1.4.3 will work ? Without erase all my data ?

Thanks

Hi Guys,

Sorry in advance bc I can see lots of people have already posted bits but they're hard to follow.

I have a mid 09 MBP 5,3 NVIDIA GeForce 9400M 256 MB and have recently installed patched Catalina and its running fine. I am unable to use F1 & F2 to control the brightness and after my MB has been to sleep my display stops working. I can see very faintly in the background text from safari etc. Can anybody help?

Thanks

I'll probably need to update the Patcher. I expect to have time to do so in the next couple days.
