If the rubber surface on the bottom of your unibody MacBook is peeling away from the case, good news: Apple has initiated a MacBook Bottom Case Replacement Program. You can either bring it in to an Apple store or service provider, or do it yourself.

[ad#Google Adsense 300×250 in story]The unibody MacBook sports a case design that uses a rubberized bottom part that keeps it from skidding across a table or other flat, smooth surface. Unfortunately, under certain circumstances, that rubberized material can peel away from the bottom case. Apple claims that unibody MacBooks shipped between October 2009 and April 2011 may experience this problem.

The program is worldwide, and while it doesn’t affect the warranty status of your computer, Apple is offering coverage for this particular problem for two years from the original purchase date. During that time, Apple will let you either set up an appointment with a Genius at an Apple retail store, bring your MacBook in to an Apple-authorized service provider, or order a replacement part via a Web page.

The replacement kit includes a new bottom case, screws, a Philips head screwdriver and instructions.
