Variable Dragging not working on osx

I love this project. I can see myself using it constantly. It really fits a niche of working between spreadsheet and notebook. I actually think you could charge for this when it's mature.

Running miniconda python on OSX Cataline, and when trying to plot, the variables won't drag over. Let me know the best way to communicate my system state, and I can give you what you need.

Here's my setup.
```bash
λ which python
/Users/rob/miniconda/envs/viz/bin/python
•_simbiz•[mac_pro][19:17:04]( master )[ ~/rob/repos/sales_ops ]
λ python --version
Python 3.6.8 :: Anaconda, Inc.
•_simbiz•[mac_pro][19:17:08]( master )[ ~/rob/repos/sales_ops ]
λ pip freeze | grep gui
pandasgui==0.2.4.3
λ pip freeze | grep -i pyqt
PyQt5==5.15.1
PyQt5-sip==12.8.1
PyQtWebEngine==5.15.1
