Apple has been having problems with the solid state storage on 2012 MacBook Airs for a while now, so it's great to see they've released a firmware updated, and replacement program, to address them. Here are the details from Apple:
Users of a Thunderbolt equipped Mac will want to head on over to the Apple Support pages and grab the latest firmware update. It's not a huge update, in fact the download is just 1.22MB in size, but does promise stability fixes for Thunderbolt and for Target Disk Mode. And we'll always welcome stability fixes.
Want to upgrade your iOS device to iOS 5? iTunes makes the process of upgrading painless. And it's just like checking for upgrades and updating any other firmware version in iTunes. The best part is once you're on iOS 5 you can start to receive OTA updates after your initial update to iOS 5.
