Hey! I had this same problem. A few things you can do (as per my google searches lol):

Restart your MAC

Use your Spotlight Search to find your 'Activity Monitor' - once you open that, click on 'Memory' to see what's taking up the most memory, then double click and select 'quit' anything you don't need. (I would delete a few things and then run the test again to see if I cleared up enough RAM storage)

Definitely run the ProctorU test again the day before, and repeat the process as necessary!

Hopefully this was somewhat helpful, good luck :smiley:
