I'm having an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory), which have been running Catalina for quite some time despite that the max OS is High Sierra. I have been using the great work by dosedudes1 and his Catalina patcher.
  1. Aug 25, 2021 The macOS 11, which goes by the name Big Sur, comes with a newer user interface and menu bars, redesigning icons and other features. It is better than macOS 10.15, Catalina, due to its powerful improvement and new features. However, Apple dropped various Mac versions, making installation of macOS 11 on unsupported Macs almost impossible.
  2. Now only the last step remains: install macOS Big Sur on your unsupported Mac. Just look for the file InstallAssistant.pkg that you downloaded. Open it and the macOS Big Sur installer will appear. Select the disk partition to install the new system and the macOS Big Sur installation process will begin.

Good luck !

Remarks
  • Erase/format the MAC HD/SSD before installation !! I really think that this does it more simple for the installer !!
    • 'Mac OS Extended(journaled)' with an old non SSD HD
    • With en SSD use 'APFS'
  • The Mac rebooted several times during install.
  • Don't remove the USB until at the very end.
  • If you, like me, have a Mac which need the legacy video acceleration support please note that the Mac have a painfully slow display update before you have applied the 'Post-Install volume Patch'.
  • Updating the Mac from Big Sur 11.4 to 11.5, made the messages.app stop working fixed in release 0.2.4
  • Please note that 'Nightly Builds' are available but are for testing purposes only !!!

  • Fixed compatibility with Catalina version 10.15.5
Read the full changelog

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. Mac os yosemite iso.

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.
