Hi,
I read that High Sierra is suitable for late 2009 iMacs or later. I have such an iMac and when I open "ABOUT THIS MAC" it shows 'LATE 2009" but when I search for updates in App store there is no High Sierra available. It responds with
'NO UPDATES AVAILABLE" Is it possible to check by serial # or production # - similar to a car where you go up to a certain chassis # and from chassis # ? Maybe mine is made just at the change-over time ???

I also checked my wife"s mid 2014 iMac for the High Sierra availability, same result: "NO UPDATES AVAILABLE". Both iMacs run on 10.12.6
Can anybody explain what is going on ?

Thanks
Walter

I have a 2017 iMac running 10.12.6, and there are 'No updates' for me either. Go figure!

Ah, but then I realised its not an update, its a new OS. So i clicked on 'Featured' in App Store, and High Sierra is there to download.

So if you Mac is new enough it will tell you there.
