Having recently downloaded the mac version of inventor fusion, I can't find the spline option that appears in some tutorials, youtube vids and the like. I suspect that this is missing - can I expect future upgrades to include it?
Inventor Fusion for Mac probably won't get a spline command.
Have you seen Fusion 360? I'm wondering if the videos you've seen are for Fusion 360.
Not only does it have sketch splines, but also T-Spline surface modeling and a lot of other awesome tools. It also runs on Mac.
Have a look! Fusion 360

As mentioned, there are no plans to put a spline command into Inventor Fusion for Mac.
Have you tried Fusion 360? It's far more powerful and has a spline command. I think you'll find the design tools you are looking for in Fusion 360.
