So after a couple restarts, it “magically” worked. I’m honestly not sure what fixed it.
eseedo, one thing you could try that other forums have recommended is to go to Preferences > Security & Privacy > General and select “Anywhere” for the "Allow apps downloaded from: " section. Although I had this selected, it didn’t work for me in the beginning, but like I mentioned, after a couple more restarts it just magically worked.
