When I change the screen brightness to an intermediate level, the light from above slowly comes in and goes out with a gap, and the brightness also jumps very sharply at about 40-50%.
what can i do about this issue?

Hi, Monitorlighting, i don’t know exactly what year and model of MacBook you have so can only give you general value help.. restart mac holding down “shift” key until you see “safe mode” on your monitor… let go of “shift” key.. is problem gone ? Then it was probably software/application problem. Is problem not gone-still there ? yes? Then is probably hardware problem.. if so then maybe call/contact apple store with genius bar or AASP ( apple authorized service provider) near you. Take it in for an evaluation. At an apple store, evaluation is always free. For AASP can’t say for sure, you’d have to contact them. I hope you have valid AppleCare+
