Apple has determined that under certain circumstances the rubber surface on some MacBooks may separate from the bottom case of the system. MacBooks shipped between October 2009 and April 2011 may experience this issue.
Apple will replace the bottom case of any affected MacBook, free of charge, that exhibits the issue.
You may choose from two options to get a replacement bottom case for your MacBook. In all cases, your MacBook serial number will be checked to verify that it is eligible for this program.
Note: If your MacBook does not exhibit any signs of this issue, no action is required on your part at this time.
If you believe you have paid for a repair or replacement due to this issue, contact Apple regarding a refund.
This worldwide Apple program does not extend the standard warranty coverage of the affected MacBook.
This program covers affected MacBooks for four years from original purchase date. Apple will continue to evaluate the service data and will provide further extensions to this program as needed.
