On a Mac Mini 2011, i7, can I just install the 2.82 GB supplemental 10.15.6 update and if it does not boot anymore, can boot from my 10.15.6 installer stick created with dosdude macOS Catalina Patcher 1.4.4 and just reininstall the patches?

Just an idea, as it should be faster than redownload the whole new 10.15.6 and create a new boot stick.
That´s exactly what you have to do.

Good choice of card. Once you have it up and running have a look at the OpenCore boot loader. This will enable you to have a boot picker screen, full H264/HEVC Hardware acceleration and OTA updates to name a few things. Works really well for me using RX580. Your 5870 would not have had much acceleration (see page 1 spoiler) so you should notice quite a difference. Make sure you did not apply any graphics patches with the patcher as these can cause issues with a GPU the does not require any.

Awesome, thank you! Hopefully I'll be able to figure open core out.

I downloaded macOS Catalina Patcher from Dosdude, created the boot with an external hard drive and when selecting the boot, the installation does not proceed. In my case, I changed the GPU (GTX 780M, with Metal support) of my iMac and I don't have the boot menu to be able to start with the Option pressed. Does anyone have an idea how to solve? Thank you!

Is the external boot drive Mac Os Plus formatted (not APFS)?

MacBookPro 5,1 here running 10.15.6 minus the supplemental update. USB storage devices appear to work but others such as a non-name brand webcam and a Blue Snowball mic do not (do not appear as accessible devices, occasionally kill the built-in trackpad). Have ensured that the latest Legacy USB patch is installed. Haven't really understood conversation about USBOpenCore in this thread. Any pointers to posts or suggestions about things that might work?

Hello, does anyone here know how the Mojave/Catalina patcher actually achieves to run MacOS on GPUs that do not support Metal? I assume MacOS itself relies on Metal support, just like some apps rely on it?
Does the patcher patch the Metal requirement out of MacOS or does it provide a "fake" Metal API on top of non-Metal-supporting GPUs? Will the patcher enable apps built on top of Metal to run properly? I'm wondering how future-proof a patched MacOS actually is, as more and more apps may rely on Metal..

"Non-Metal GPU application support: When running Catalina on a machine that does not have a Metal-compatible video card, the included Maps and Photos apps will not function properly." The first page show the most prominent lacking feature of the photos app.

You can have graphics acceleration even with non metal compatible cards, but not all and everything will really work. For some apps like zoom @dosdude1 made patches, but IMHO on the long run you will need a metal card to enjoy full compatibility of all apps. The more new apps you are going use the more incompabilities you will face.

The same is true with Continuity and HandOff which needs from MacOS version to another version a more recent hardware support (BT 4.0 and WiFi ac). SideCar is another thing relying on HEVC support of modern Intel CPUs (may also work with modern AMD graphics cards). You cannot convert and upgrade every old system, but some. The MacPro series is a such a system, some iMacs like the mid 2011 with some limits, too.

Apple announced to deprecate OpenGL entirely and move completely over to Metal. Mojave has been only the first step.

Hi there.

With MacBookPro5,5 / GeForce 9400M, when plugged into my 2010 iMac via mini-DisplayPort, I get full 2560x1440p resolution and it looks great. However, audio over mini-DisplayPort doesn't work. Is that to be expected with this Catalina patcher?

Did you select the correct audio source in Preferences?

Hello, I have an iMac 21” 2012 Fusion Drive which supports Catalina, I had terrible performance compared from High Sierra and I was trying to install Catalina on HFS+ only. I am using @dosdude1 patcher to do a clean install on HFS+ formatted volume, but after the installation finishes, I see that the Fusion Drive has two APFS volumes created, system and data.

Can you help me on this? I only want to use HFS+ on Catalina

APFS is the standard with Catalina, now. There are ways around it, but I do not know if it is worth the extra milage.

BTW: Why you are not using the standard installer? There is no gain in using the patcher here?

It’s not listed as an output option.

Works if I use my 2017 iMac.
My iMac is Mojave. However, I just tried with my 12" MacBook under Catalina, and it sees the audio output over mini-DisplayPort too just fine (via a USB to mini-DisplayPort dongle).

Audio wasn't supported until Mid-2010 and your MacBook Pro is a Mid-2009. :)
OK thanks. That explains why my Mac Pro 2,1 (2007) with Radeon HD 5770 also gives me no audio over mini-DisplayPort either, with 10.7 Lion and 10.11 El Capitan.

Interestingly, I do get audio with Windows 10, but it's pretty glitchy.

I can't speak for the Mac Pro as I don't know if it is just the hardware or the firmware that prevents it, though on the MacBook Pro you are right, it does work in Windows as I recall. Oh Apple. :)

While the DisplayPort specification can support digital audio, the older 2009 line of MacBooks, MacBook Pros, and Mac Minis cannot provide an audio signal through the Mini DisplayPort, and only do so over USB, Firewire, or the audio line out port. (The April 2010 line of MacBook Pro, and July 2010 iMac and later do support this[15]). This can be a problem for users who want to connect their computers to HDTVs using a Mini DisplayPort to HDMI adapter. To work around this issue, some third-party manufacturers have created dual or triple-headed adapters that get power for the adapter from a USB port, video from the Mini DisplayPort, and audio from either the USB port or the optical-out port. Either option terminates with a single female HDMI connector, thus allowing both video and audio to be channeled over the single HDMI cable.[16]

The 2008/2009 models never had audio out over DisplayPort, sorry. Doesn't have anything to do with the patcher, it's the machine itself.

Hi Everyone,

Attempting to install Catalina on 5,1 MacPro, currently running latest Mojave, no issues, other than the NVIDIA graphics card (Quadro K5000) insisting on a CUDA driver update that can never happen. Running the Catalina Patcher, I'm encountering "Error Saving BaseSystem Image"...."ensure there is at least 10GB of free space on your startup disk...."

Somebody else back in November had this issue, but posted a unique thread, and was directed to this one instead - but can't find that that person had posted here about the issue. Sorry if this has already been covered, I looked through many pages (not all 484 however...), and nothing jumped out at me. Would appreciate if somebody could direct me to posts if they exist, and if not, if you can offer help! Not sure where to go from here.

Have tried this on a few computers now, with multiple external drives (USB, Conventional, SSD - all well in excess if that 10GB free space, all empty, properly formatted), as well as the method of direct install - always the same result. Viewing the error log shows that hdiutil: couldn't unmount "diskXX" - Resource Busy, that disk being the Catalina Base Image. ?

Any help, greatly appreciated. Thank you!
