Document macOS caveats on binary installation tutorial

[chapulina]

The install tutorial for macOS from source lists caveats and extra tips to get Ignition to work:

https://ignitionrobotics.org/docs/citadel/install_osx_src

While the binary install tutorial suggests that everything will just work out of the box:

https://ignitionrobotics.org/docs/citadel/install_osx

We should make sure that users installing from binaries are aware of caveats and any extra steps needed.

Thanks, @ahcorde . Are you working on more PRs or do these cover everything?

These are the two issues that I have found. Maybe I can add the gazebo_scene_viewer as an alternative to visualize what's going on in the scene.

What do you think ?

I think the main problem is the sentence "All libraries should be ready to use and the ign gazebo app ready to be executed.", which gives the impression that everything should just work. I think we should document in those tutorials that the 3D scene doesn't work and that ign gazebo should only be run headless, see gazebosim/gz-sim#477 as a reference.

We should document this for Citadel, Dome and Edifice.

I see this is already documented
