Thanks for responding! I do agree that article could be better, so we're going to update that to include more specific information for Outlook for Mac.
To get the latest version of our Outlook add-in on a Mac, you'll want to click on the red Store button in your Outlook ribbon, search for HubSpot, and then toggle that add-in on. If you're unable to see the Store, you may want to update your Outlook and check to see if you have an O365 subscription and compatible inbox. For more help on this, please check out this article.
