In this video, I go over the process of installing macOS 10.15 Catalina on an unsupported Mac. This entire process involves the use of my 'macOS Catalina Pat. The macOS Catalina Patcher tool will definitely work fine to install macOS on the above unsupported Mac. This problem is occurring for thousands and maybe a million Mac users, so there’s a should be a solution. MacOS Catalina Patcher. The easy way to run macOS Catalina on your Unsupported Mac. Download Latest Version View Changelog. Using the Patch Updater tool, it is possible to re-install these patches with one click. To do so, open the Patch Updater application, and select 'View Installed Updates', or use the 'View Show Installed Updates' menu in the Menu Bar. To re-install a patch, simply right-click on it in the list and select 'Re-install'. That patcher (or possibly any that patch Catalina) doesn't work for you. So find a working method for your system or give up the quest for running unsupported macOS on your Mac. Sorry but seems like all that is left.

MacOS Catalina won't work on older Macs, but thanks to dosdude1's patcher, it can! Dosdude1 himself makes a cameo in this episode.

  1. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled).

  2. Open the 'macOS Catalina Patcher' tool, and browse for your copy of the macOS Mojave Installer App.
  3. (Friendly Reminder: Ensure that the tool successfully verifies the app.)

  4. Next, select your USB drive in the Target Volume list, and click 'Start Operation.'

  5. When the operation completes, boot your target unsupported Mac off the USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive.
  6. (Note: Only perform steps 5 and 6 if you intend to do a clean install. Otherwise, you can simply skip these steps and install to your volume containg a previous version of OS X, and it'll do an in-place upgrade.)

  7. When the installer boots, open Disk Utility from the Utilities menu, or by double-clicking it in the Utilities window on the bottom left corner of the screen.

  8. Select the disk or partition you want to install on, and erase it, ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type. If formatting an entire drive, ensure GUID is selected.
  9. (Important Note: Using APFS is REQUIRED in Catalina in order to receive system updates via the normal Software Update method. If you choose to continue using macOS Extended (Journaled) as your filesystem type, you will NOT receive System Updates via System Preferences.)

  10. Install macOS normally onto the desired volume.

  11. When the install completes, reboot back onto the installer drive. This time, open the 'macOS Post Install' application.

  12. In the application, select the Mac model you are using. The optimal patches will be selected for you based on the model you select. You can also select other patches of your choosing.

  13. Select the volume you have just installed macOS Catalina on, and click 'Patch.' When it finishes patching, click 'Reboot'. It may sit there for a few moments rebuilding caches before rebooting.

  14. When it reboots, it should now boot into a fully working copy of macOS Catalina.
