Apple addressing cracks on white MacBook casings
After looking at the photos posted as part of this report, I took a look at my own MacBook and didn’t see cracks in the case locations in the examples. However, I kept looking… and… ack, there they were! Three hairline cracks in the case. I couldn’t believe it. My MacBook has never been dropped. And, I handle it very carefully.
I guess an appointment at the Genius Bar is in order after I do some more research on the topic.
