Alex, that won’t work. They only will upgrade within a major version. 10.11.6 combo will only upgrade 10.11 versions, not 10.10.

The 10.11.6 installer actually is on the app store. There is some method to get to it through the mac OS upgrade selection.
I’ve done it, but don’t remember how. At this point my purchase history includes installers for versions on macOS and OS X going back a ways.
I just pulled the latest 10.11 last evening, which is why I know for sure it is still available.

Hi All,

I’m trying to update an old Mac Pro Early 2008 from 10.10.5 to 10.11.6, does anyone know how to do this?

I can’t find it on the App Store and can’t find a separate .dmg file to download…..

Any help or suggestions greatly appreciated.

All the Best
Dave
