They didn't release new 0.92 packages for Mac and apparently don't plan to.

Noooo! are you aware of any third party binaries?

.92pre4 is available on macports, so they'll probably make .92 available soon.

There's an inkscape cask for homebrew. You should be able to compile it on your own too.

The cask is 0.91, and uses the .dmg file.

I'll subscribe to their dev mailing list and see about volunteering to get the macOS version out.

No, it is not. That is 0.91, not 0.92.
