What is the highest MacOS this Mac has had?

I've seen some people that require El Capitan first...

Hi guys

on that mac book I install el Capitan not high sierra (been long time since I saw those) so that iMac runs el Captain now. Running update not showing option to upgrade to high sierra and my questions is: what is the best option to upgrade to HS ?

BTW those freezes and kernel panics was due to bad memory. This iMac have 3x2gb and 1x1gb and for now I running 2x2gb samsung and for few days nothing.

thanks
