Is there a "permalink" for Sierra at the App Store? Upgrading, but I'd rather stick with Sierra until MacPorts is ready for High Sierra.

In the App Store purchased tab, I see OS X Mavericks and the rest of the set, but I never installed Sierra. If I search for one version in particular, either it doesn't come up or I'm sent directly to High Sierra.

How do I search for the entry for Sierra (and exclude High Sierra) on the App Store? Do releases have any sort of "permalink"?

Relevant:


Modify "Release date" in the featured tab. There is no such thing.
Downloading a release older than the current is no longer allowed (?).
Another hint that this may not be possible. That would be very frustrating. High Sierra is useless for me until MacPorts for High Sierra comes out. (How long that will take is a separate question.)
Yes - Contrary to past OS releases, Apple has an article with links to the store and detailed requirements for getting and installing macOS Sierra (even after High Sierra is out).

I would use the help article HT20802 to check for an updated link if the Mac App Store one fails you, but the one above is live now on the store.
