Many people still love their old iMacs. You too know one? Well, I know a few as I happen to be one of them. Still in love with my old 2011 year 27” iMac that till now ran Mac OS High Sierra. And then, one day it stopped upgrading anymore. Reason…? Apple had changed everything to a 64-bit distribution system leading to first of its types Mac OS Mojave. I so badly wanted a solution to upgrade my system to the new OS but it just failed. I almost hated Apple for this as they bullied us to purchase a new computer. I was adamant though to keep trying and upgrade this to the new Mac OS. Several of our customers called us in to find a way to upgrade their MAC computers but we “Computer Repair Onsite” did not have a solution for them. Time passed and soon there was this new Mac OS by Apple called Catalina. It looked really cool and my eagerness to get upgraded on it increased even more. Finally I got to know about a patching tool, called DosDude.
DosDude Catalina Patcher is a third-party tool that helps the users to patch the Mac OS Catalina installer on otherwise unsupported Macs. Of course, just because you can do this, doesn’t mean you should, as there’s a good chance that performance will be sub-optimal, while Catalina features may depend on modern Mac hardware (Sidecar, for example) and likely won’t work at all. You can find a compatible list of unsupported Macs for Catalina Patcher on the DosDude website.
