Dear,

I wish to batch process using `pvpython` but in my system (`MacOS, 13' MBP, ParaView 5.9.1`) no rendering window pops up when I try to reproduce [the sphere example](https://docs.paraview.org/en/latest/UsersGuide/introduction.html?highlight=pvpython#id4). I believe this might be due to the issue already mentioned here: [macOS: pvbatch/pvpython raise PYTHONHOME errors](https://gitlab.kitware.com/paraview/paraview/-/issues/20335). If that is the case, is there any workaround for the moment (until the bug is fixed)?

I doubt it has anything to do with the PYTHONHOME errors. If you’re see no other errors and you’re using `pvpython` (and not `pvbatch`) most likely the window has popped up behind your active windows. Try using `Expose` to locate the window.

Hi Utkarsh,

thanks for your response. I’m afraid I don’t understand what you meant by `Expose`. I use the App Exposé offered by MacOS [Show or move all open windows](https://support.apple.com/en-in/guide/mac-help/mh35798/mac), and I’m sure there are no windows popping up. I am providing what I did:

```auto
$ ./pvpython
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Python 3.8.8 (default, May 17 2021, 13:00:49)
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin

>>> from paraview.simple import *
>>> Sphere()
<paraview.servermanager.Sphere object at 0x10e523730>
>>> Show()
<paraview.servermanager.GeometryRepresentation object at 0x1180b4cd0>
>>> Render()
<paraview.servermanager.RenderView object at 0x1180b4dc0>
>>>

```

Looks like MacOS is not returning any window, but why?!! 🤔

With regards to “Expose”, I’m pretty sure Utkarsh means [What is Expose? - Switch To A Mac Guides](https://switchtoamac.com/guides/mac-os-x/expose/what-is-expose.html). On my Mac, using a generic keyboard, the magic commands are CTRL-UpArrow. On my MacBook, use four fingers, and slide up.

Okay, I am sure it’s not an hidden window issue. No windows is popping up at all. Anyone isn’t using `pvpython` in a Mac, having such issue?
