On the upper left side (where the charger port is) of my Macbook Air, the aluminum is chipping off of my laptop. It is not a matte silver, but a shiny color, like a knife.

I don't abuse the computer at all.

However, I do carry it around in my backpack a lot for college. I keep it wrapped in a plastic bag (in case it rains), so it is rubbing and bouncing against that all the time.

Could that be causing it?

Is this normal?

The rest of the computer looks fine to me.

There are zero performance issues with the computer.

Thank you for your time.

Sounds like a Terminator T1000 is morphing! :D

Been scanning the many forums and this is the first time I hear of this, so no, I won't say it's "normal."

If you found a piece actually came off, I'd say it's a factory defect.

If it's just a shinny spot like rubbed off, I say something is been rubbing the same spot constantly.

What does the mac rub up against while traveling with you? Is the location where you damage occurred always in the same orientation in the backpack?

My original (2008) MBA had lots of 'chipping' along the edges (mainly the front below the keyboard) but neither the 2010 and 2013 models I still have show similar wear. I suspect they're made of a stronger metal, as I don't think I've been more gentle with them.
