System requirements macOS 10.15 Catalina

macOS Catalina will run on all Macintosh computers that supported Mojave:[1]

MacBook: Early 2015 or newer

MacBook Air: Mid 2012 or newer

MacBook Pro: Mid 2012 or newer

Mac Mini: Late 2012 or newer

iMac: Late 2012 or newer

iMac Pro

Mac Pro: Late 2013 or newer; Mid 2010 or Mid 2012 if upgraded with a recommended Metal-capable GPU

A Mac Pro 2010 can install Mojave if it has a Metal capable graphics card.

Install macOS 10.14 Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012) – Apple Support

But it cannot upgrade to Catalina only Mac Pros from 2013 (Trash Can) and newer can install it.

Of course searching for unsupported macs outwith the confines of these communities may

open your mind to new possibilities.
