How do I update iMac end 2013 from 10.10.5 to 1...

I would like to wait some more time before upgrading iMac (end 2013) to OS 10.13. How do I upgrade from 10.10.5 to 10.12.6 ?

Sierra is no longer available from the AppStore, your only choice is High Sierra.

Thank you. Yesterday I had the same issue on my Mac Book Pro mid 2012 10.10.5 but I was able to download 10.12 Sierra from the list of purchased apps in the APP STORE app. This is because on another iMac I installed Sierra in Dec 2016... The problem is that now in the APP STORE purchased app section there is no Sierra anymore ...

Yes, if you previously purchased Sierra you can re-download it from the AppStore. Try downloading it on the other Mac and copying the installer.
