I just got a new MacBook Air (2017 - Upgraded from a 2012.) Every website I go to works like a charm, except canvas. I can log in with no problems or delays, but when it gets to the dashboard, there are only boxes and "loading" symbols where my Classes should be, and they never load. iI've waited up to 20 minutes with no progress. 

Bottom line, I currently cannot use canvas on my new computer, and I have no idea why. 

Please send help!
