My Macbook air will boot up and load the full bar under-neath the apple logo but when the bar gets full it freezes and wont go to the user sign in page I am not sure what to do?
The most common problem I’ve seen on this model with this symptom is a full hard drive. This is especially true right after a system upgrade. Try starting in Safe Mode by holding down the Shift keyon start up. That failing hold down the Option key on start up and go to the recovery partition and run Disk Utilities.
