The two softwares are completely identical, with the one difference being that the evaluation version only lasts for 90 days.

The install process is almost exactly the same. Now, since I have a full license key, that's the version I'm picking, but if you just want to try Rhino, go ahead and click on the evaluation. First is the evaluation version, and this links to a fully-functional free version of Rhino with a license that lasts for 90 days, or we can choose the latest version, and this requires a full license key. Basically have two different options here. What we really want though, is this complete install for Mac. Just as a quick aside, in addition to the full version of Rhino for Mac, there's also an iOS app that lets you view Rhino files on your iPad or your iPhone, as well as a few different versions of Rhino that account for different plugins. So let's look over here on the right, where we have stuff for Mac.

On the left is downloads for Windows, and obviously that's not what we're interested in today. So I'll go ahead and click on the download link, and this takes me to the downloads page. The first step is to launch a web browser and navigate to /mac. Let's take a look at downloading and installing Rhino 6 for Mac.
