I have attempted to update my MAC from OS High Sierra to OS Catalina and it will not update until I update to a later version of High Sierra version 10.15?
I am NOT technical and I just want to update the operating system.
What iMac sub-model? That is very important because older iMacs cannot run the latest operating systems.
You find your sub-model from "About this Mac.." under your Apple menu:

Your iMac must be a 2012 or late model to run Catalina.

Having just been through that process I think you have to do all the updates.
I don't think you can jump to the latest.
I cannot update my iMac from OS High Sierra to OS Catalina and I do not know why?
