Download macOS Catalina Patcher 1.4.5 – Download Free

macOS Catalina Patches (before macOS Mojave Patch, macOS High Sierra Patches and macOS Sierra Patches) is a small but powerful tool that helps you create a bootable USB drive that can be used to install macOS Catalina on Mac computers prior to mid-2012, essentially acting as a macOS Mojave patch for unsupported Macs.

The tool extends the list of compatible hardware to include Mac Pro, iMac, and MacBook Pro computers released in early 2008, aluminum unibody MacBooks or MacBook Airs produced 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

In order to be able to use the application, you must ensure that your USB drive has at least 8 GB of free space and that the macOS 10.15 Catalina installer application is installed on your Mac.

Note that you can only download macOS images from the Mac App Store app on Catalina-enabled machines: otherwise, you’ll have to find an alternative solution.

For your convenience, macOS Catalina Patcher offers you the possibility to download images 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.

An easy-to-configure patch tool that creates a bootable macOS Catalina USB

In the main window, you just need to 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 in order, all you have to do is press the start button.

You can choose to monitor the process in the main macOS Catalina Patcher window, and the utility will notify you when tasks are complete.

It’s worth mentioning that after installing the operating system using the macOS Catalina Patcher bootable drive, you must launch the macOS Post Install utility to access patches designed for your Mac model.

Make a bootable drive that lets you install Catalina on an unsupported Mac

On top of that, if your Mac was built before early 2008, chances are you won’t 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, it was created to be used as an unsupported Mac if your Mac is not on the compatibility list for macOS Catalina Mojave patch.
