Can I install High Sierra on my 2016 Mac Book which is running Sierra.. I can't find it in Apps Store.

Thank you kaz-k. When I do this I get the warning box ' This copy of the Install macOS High Sierra application is damaged, and can't be used to install macOS' I got this earlier and also got it when I clicked my icon in Launchpad. I aren't given the Get option, just the Open option.

Thank you ku4hx. Will Pages still work for me? I've been led to understand that this might not work if I upgrade to Monterey. I use it a lot, so I'm cautious. I've also been told to move up in small steps rather than make one big jump.
