Shoot! I actually just went to buy it (you had me sold with your quick reply) and found that it requires 10.9+ :(<p>I&#x27;m on Mountain Lion with both of my MacBook Pros. I won&#x27;t be upgrading until I sell these and buy a new one (which will be at least a couple months - waiting for El Capitan, as I&#x27;ve heard too many nightmare stories about Yosemite).<p>In the meantime, your eagerness to connect (e.g., via HN this morning) with your customers is going to help you greatly. I&#x27;d definitely add the menu option, if it&#x27;s easy, but make sure it&#x27;s polished and looks great on a Retina model (Mac users have grown accustomed to helpful menu items on apps like this).
