#HOW TO UPGRADE MAC OS 10.11 TO 10.12 UPDATE#
I do a lot of work with statistical software and because I can't update my Mac there are certain functions and programmes that are starting to become unusable. <- this is the direct example of when I tried to just update it to Sierra.

When I say 'doesn't work', it starts installing (the window pops up) and then another window pops up saying: This version of macOS 10.12.6 cannot be installed on this computer. Kindly note that a fresh installation of macOS would remove all the existing data, apps, or saved settings from your system. In this case, you can perform a clean installation of macOS Catalina 10.15 from scratch. I have then tried manually updating from the Apple website database - doesn't work. If your Mac has inherited some problems, then an upgrade won't be able to fix it. Reinstall while keeping files, applications, and settings Reinstall while erasing everything on your computer Upgrade from previous versions to OS X 10.11 (El Capitan) From the Apple menu, select App Store.

I have also tried looking through App Store and manually updating that way - doesn't work. Upgrade from previous versions to OS X 10.11 (El Capitan) Reinstall El Capitan on a computer already running it. I have tried via the classic Software Update route but nothing comes up. I want to update it as I appreciate that El Capitan is well out-of-date and my apps (and system in general) is starting to reallllllly slow down. I currently have an iMac (20-inch, mid 2009) running on OS X El Capitan (version 10.11.6).
