Hi,
I followed the steps in [TTK - the Topology ToolKit - Topological Data Analysis and Visualization](https://topology-tool-kit.github.io/installation-osx.html)
to install paraview on Mac OS X Catalina. However, after installation, I’m running into the following issue whle trying to launch paraview:

Hi Shan,
This looks like a problem with the TTK team’s packaging of ParaView. You will probably want to reach out to [them](https://topology-tool-kit.github.io/contact.html).

Looking at their experimental package, it looks like it is not installing a valid ParaView application bundle at all.
