Ive got a 2012 Mac mini here thats running high Sierra just fine. This machine, as well as being newer, is a lot beefier but I don’t want to bog it down… and I keep hearing people talk about Mojave being slow on (i assume) newer machines than mine and Catalina likely more so… And I wonder if this hardware will be up to it! A few months back it got upgraded to High Serra… and slowed to crawl for many things…

The reason I ask is that at work I have an even older 20' iMac. Right now I am running Sierra… I know I can go High Sierra and will be be able to run Mojave and even Catalina… but with this hardware should I upgrade and if so just to High Serra or higher? It still seems plenty snappy for my uses.
