with concurrent.futures.ThreadPoolExecutor(max_workers=16) as executor:

Errors are either Segmentation Fault: 11 or Abort Trap: 6

@bsergi and @bradystoll since you both also have Macs could you see if you get the same error whenever you have some spare time? You'll just need to process and attempt to make some plots for the example data now located on main https://github.com/NREL/Marmot/tree/main/example-data/hourly

The data processes in less than 1 minute per scenario so shouldn't take too long. The user_input_file can be quickly setup by using the values described in the Tutorials https://nrel.github.io/Marmot/get-started/index.html

Solved on mac by reducing number of multithread workers in yaml

Edit method to bypass multithreading code if max workers = 1.
