Hi all, my macbook air has been glitching majorly recently and I’ve reset the SMC and no luck. As you can see I have a small crack in the corner which could be contributing however it was not an issue when it happened which was a few months ago.
Setup for an Appointment with an Apple Authorized Service Centre to have it evaluated and or repaired.
