I would like to make an appointment to bring my MacBook Pro in. I have flickering thin white lines on th screen. I've spoken with tech support about it and after checking possible causes, they suggest I bring it in for service.

Sandra, This is a public forum fir people to leave reviews of their visits to the store. I'd suggest you follow Apple Tech. Supports instructions and bring the device in for service. My experience with staff at that store has always been wonderful. They are very helpful. Ken Johnson
