Installing Catalina OS
Hi, I work in a production environment, and as such, we don't have chance to keep up to date with Mac OS's, as there are various workflows and tools that we use which often don't keep up in regards to compatibility (Esko etc). So, I need to update to Catalina, but I'm finding it extremely difficult via the App Store. It just doesn't seem to be there - and doing it through Apple support gets me to the right place, but there's no 'Get' or 'Cloud' button which I was expecting... Can anyone help?
