I bought a MacBook Pro about 3 weeks ago from an Apple retail store, but I had a weird screen issue where it kept shutting off randomly so I requested an exchange a week after. Ever since, there were just so many problems with the new MacBooks and I had to exchange it 3 times. I am on my 4th Macbook, but I am not really satisfied with this one because I just had a kernel panic (where the computer randomly restarts). Also, the screen is yellowish and the wifi keeps disconnecting after a while. I don't want to get an exchange from that retail store again, so I am thinking of ordering a brand new macbook directly from the online store. My problem is, however, that I am really afraid to go back to that retail store to ask for a refund.. Some of the employees know me now and I feel like I'm abusing the system, when I am clearly not. But the fact that it's going to be my 4th time returning their product raises suspicion. I'm also afraid that they might not accept this refund.. Does anyone have any advice?
