First of all, get a USB drive with at least of 8 GB of free space and download MacOS High Sierra Patcher.

Running Catalina without full graphics acceleration will result in extremely poor system performance. If you have a machine with one of these GPUs installed, I'd advise upgrading it if possible (can be done in 2010/2011 iMacs, iMac11,x-12,x), disabling the dedicated GPU if using a 2011 15' or 17' MacBook Pro (MacBookPro8,2/8,3, instructions to do so can be found here), or not installing Catalina.

When installing, ensure your system is plugged in to power, or the update will not be installed. If you have NOT previously installed High Sierra, you can download and install this package to install the latest BootROM version. Important InfoĪPFS 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. Do not attempt to install macOS Catalina on computers that are in the Not Supported list. Also consider creating a Time Machine backup before proceeding with an installation and look through System Compatibility section. MacUpdate team strongly suggests not to install macOS Catalina if you only have one computer or if it is your main machine. It can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012. MacOS Catalina Patcher lets you install macOS Catalina on Mac computers that are no longer officially supported.
