macOS Catalina Patcher 1.4.4

macOS Catalina Patcher lets you install macOS Catalina on Mac computers that are no longer officially supported. It can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012.

Important disclaimer

MacUpdate team strongly suggests not to install macOS Catalina if you only have one computer or if it is your main machine. Also consider creating a Time Machine backup before proceeding with an installation and look through System Compatibility section. Do not attempt to install macOS Catalina on computers that are in the Not Supported list.

Important Info

APFS BootROM Support: If you have a machine that supports High Sierra natively, you MUST ensure you have the latest version of the system’s BootROM installed. If you have NOT previously installed High Sierra, you can download and install this package to install the latest BootROM version. When installing, ensure your system is plugged in to power, or the update will not be installed.
