Matlab 2018b running very slowly on Macbook Pro 2015

I recently upgraded from 2016b to 2018b, and Matlab is now running VERY slowly. Activity Monitor says that Matlab is using 1.07 Gb of ram. That seems like a lot, although admittedly I never checked what 2016b ran at since this was never an issue. Does any one else have this issue or know how to solve it?

Do you have the Magnet App open? If so take a look here.

Me too. I updated from 2017b and the editor freezes the computer. I have a full specs Macbook pro from 2014.
