Essentially the Catalina Patcher Tool creates a modified USB installer drive (similar to the regular Catalina boot installer drive you can make) which you can then use to install not only macOS Mojave on the otherwise unsupported Macs listed below, but also a series of patched macOS Mojave component files that allow it to boot.

Just a quick word of caution: while you may be able to get macOS Mojave running on an unsupported Mac, this is true only for advanced users who are adventurous. You certainly wouldn’t want to try this on a Mac that you must have to perform in an optimal setting at all times, or on your only computer, but if you feel like tinkering around and running macOS Mojave on an unsupported Macintosh computer you can certainly try it out. Because it patches the operating system and installer, not everything is going to work perfectly on all machines — for example, on some machines networking may not work, or an iSight camera may not work, or GPU acceleration may not function — and there could be various bugs, performance quirks, and other theoretical problems with attempting this, but for the truly tech-savvy and brave, the Mojave patcher tool and accompanying walkthrough from DosDude can get the job done.

The DosDude website has both a complete tutorial available at the above link, along with the downloadable patcher tool.

OR you can also make an entirely new Hackintosh for yourself.
