Added a check for macos such that the updateHeadsUpDisplay is not called to fix the scatterplot crash

What is the actual issue here? This does not seem to fix any underlying issue, but rather ignore it...

When we open a scatterplot, it crashes on this line:
const auto datasetsItem = getHeadsUpDisplayAction().addHeadsUpDisplayItem("Datasets", "", "");

but does not show any useful error message.

Happens only on Mac and if there are datasets in the data hierarchy.

So, inorder to create the installer, I discussed with ThomasK and disabled it for Mac.
