    Catalina Patcher update: Unfortunately, due to some major issues encountered with patching 10.15.4, the current Catalina Patcher version has now been reverted to 10.15.3 support only, and will only download 10.15.3 installers. Do NOT attempt to upgrade to 10.15.4 at this time.

    Just released the first non-beta version of Catalina Patcher! Now, all installation methods are implemented, and I also added a logging feature for more easily resolving issues. I've also completely redesigned the Catalina Patcher webpage.

    I have just updated Catalina Patcher to version 1.0 Beta 9, which now includes a software APFS booting implementation. This means that having native APFS support in your system's BootROM is no longer required to run Catalina! Download can be found at

    NEW Catalina Patcher pre-release out, with all new UI! It is not fully implemented yet, but it still will allow you to create a patched installer for use on an unsupported system. I plan on having the full implementation done in a couple weeks.
