I'm a huge supporter of things best of the best, but sometimes faulty parts from various manufacturers can be hazardous to your continuous happiness in the world of computing. If you don't back up on a regular basis, this recall should be of concern to you! Posted yesterday on Apple's website, they are launching a recall on the MacBook Airs purchased between June 2012 to June 2013 for faulty flash storage drives. Warning users to not install any updates, you can verify if your MacBook Air is affected following the simple steps on the Apple website.
This is a free replacement so I would schedule an appointment at your local Apple Store Genius today and get it done!
To see if your drive may be affected, go to the Mac App Store, click on Updates and choose the MacBook Air Flash Storage Firmware Update 1.1. The firmware update will test your drive to see if it is affected. You will be directed back to this page for next steps if needed.
