My game won't update (Mac)

My game just won’t update. I’ve tried three times already, restored the EA app, etc. But the update download is insanely slow. My internet connection is stable, everything else is working fine. I don’t have any other devices on WiFi, yet the download speed keeps dropping until it’s down to 20 kb/s until the whole thing just stops moving. I’m losing it. Does anyone have any ideas on how to fix this?
