A few days ago my MacBook Air just decided it was going to run REALLY slow when opening applications, and it connects to wifi but there’s no internet. I’ve connected to my home internet, my neighbours home internet and tried to hotspot from my phone with all the same results, so my internet is not the issue. Does anyone have any ideas I can try?
