Have been using this Patcher for years now on my Mac 3,1 and it still runs the latest Mac OS Catalina. Thank you dosdude you are a genius. Literally just had the same exact thing on the same model doing an upgrade on customer's mac. I've done probably 100 installs of dosdude's patcher and haven't seen this before.
Helps you create a bootable USB drive for macOS Catalina which will work with older Macs, not officially supported by the operating system
What's new in macOS Catalina Patcher 1.4.4:
- Fixed compatibility with Catalina version 10.15.5
macOS Catalina Patcher (formerly macOS Mojave Patcher, macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012, basically acting as a macOS Mojave patch for unsupported Macs.
The tool extends the list of compatible hardware to the Mac Pro, iMac and MacBook Pro computers released in early 2008, Aluminum Unibody MacBooks or MacBooks Air manufactured in late 2008, or white MacBooks and Mac Minis produced in early 2009.
Get the macOS Catalina Installer app and make sure you have access to a compatible USB drive
To be able to use the app you must make sure that you have a USB drive that has at least 8 GB available, and that you have the macOS 10.15 Catalina installer app on your Mac.
Note that you can download the macOS image from the Mac App Store application only on a machine that supports Catalina: otherwise, you must find an alternative solution.
For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu.
At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.
Easy to configure patcher tool that can create bootable macOS Catalina USBs
Within the main window, you must simply load the macOS 10.15 image you want to use and select the target USB drive. The app will verify the image to make sure everything is OK, and all you have to do is press the Start Operation button.
You have the option to monitor the process in the macOS Catalina Patcher main window, and the utility lets you know when the task is complete.
Worth mentioning is that after you install the OS by using the macOS Catalina Patcher bootable drive, you must launch the macOS Post Install utility to get access to patches specifically designed for your Mac’s model.

Make a bootable drive that allows you to install Catalina on unsupported Macs
Bottom line, if your Mac has been manufactured before early 2008, chances are that you will not be able to install macOS Catalina on your computer.
All things considered, macOS Catalina Patcher is a small and user-friendly utility designed to help you bypass this limitation if your Mac is not in macOS Catalina's compatibility list, created to be used as an unsupported Mac Mojave patch.

Until macOS 10.15 Catalina, Mac users knew: their startup volume was a single volume, just as it appeared! (Okay, for Fusion drive users, there are two physical drives managed by software to appear as a single “disk drive,” but that’s separate from the data organization that is a volume on a drive.)

As I wrote a couple of months ago, Apple relies on a feature in APFS (Apple File System) called “volume group.” This allows macOS to link together two separate volumes to appear as a single drive. Apple chose this method as a way to enhance security, putting read-only system files on one volume and your changeable data, home directory, preference files, and all the rest on another.
But where does this leave you if you want to clone your startup volume and create a backup that can be used as a one-stop shop for restoring a failed drive or Mac, or which can be booted from? Fortunately, all the software you need is up to date.
Time Machine correctly archives your entire startup volume (as well as other volumes you might specify), letting you restore a Catalina drive as you would a previous version of macOS.
Carbon Copy Cloner ($40) has supported making full clones that boot with Catalina since August 2019. If you haven’t used CCC in a couple of years, you need version 5 for Catalina support.
SuperDuper! ($28) released version 3.3 in November with full Catalina backup and boot support. Its maker, Shirt Pocket Software, has never charged for updates, so if you own any previous release you can download and use the latest version.
