MacBook Air Flash Storage Firmware Update was launched last night by the company Apple Lossless Audio CODEC (ALAC),, the update having the role of solving some problems that the flash storage space of Macs generates for users. The problem only affects MacBook Air- with flash storage of 64 - 128 GB sold between June 2012 and June 2013, so we are talking about the old model of the product. Unfortunately, this problem can cause the loss of data stored in the company's storage media Apple Lossless Audio CODEC (ALAC), easily replacing any MacBook Airs that cannot be updated, the installer automatically detecting whether your product falls into this category or not.
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.
IMPORTANT: If your drive is affected, we strongly recommend that you do not install any operating system updates or new applications. We also recommend backing up your data on a regular basis until you receive a replacement drive.
The update is available through the Software Update system, but you can also download it from this page.
