How To Update Mac OS When No Updates Showing In The App Store | How to get old versions of Mac OS
Ever go to the App Store and try to download the Mac OS update big sur, and for some reason it just won’t work? when you click it does nothing happen ? Or when you click it does it say calculating for hours and hours and even days ?
This is the order that the operating systems go in from Top to Bottom (Newest to Oldest).
1) Big Sur
2) Catalina
3) Mojave
4) High Sierra
5) Sierra
6) El Capitan
7) Yosemite
This order is very important because you are unable to jump any of the updates, for example : going from El Capitan Update to Mojave, you will not be able to do that. You would need to go to Sierra, and then High Sierra, and finish off with Mojave.
Every single install of operating system needs to be done in order to move on to the next possible operating systems. No Skipping.
Make sure that you save all of your work and files to avoid losing any of your important files, before attempting these updates.
Disclaimer: If your hardware in your computer is too old, you will only be able to download the operating systems to a certain point until it will no longer be compatible.
