Apple has released a critical update today for the mid-2012 MacBook Air. The update, entitled MacBook Air Flash Storage Firmware Update 1.1, is intended to check the build-in SSD drive in the MacBook Air for “an issue that may result in data loss”. The tool tests the drive, and if it checks out, installs new firmware.
If the tool finds your MacBook Air’s drive to be faulty, Apple has launched a replacement program for the mid-2012 MacBook Air entitling you to have the drive replaced by Apple free of charge.
From the release notes:
This firmware update is recommended for MacBook Air (mid 2012) models.
Apple has discovered that a small percentage of flash storage drives in these MacBook Air models have an issue that may result in data loss. This update tests your drive and, in the majority of cases, installs new firmware to resolve the issue. If your drive cannot be updated, Apple will replace it, free of charge.
The update weighs in at just over 2MB, and is available through Software Update on eligible devices, or for direct download from Apple.
