MacBook Air firmware update available to fix potential data loss issue

18. October 2013 Security 2

Apple has released a firmware update that is recommended for all MacBook Air (mid 2012) models. The update webpage reads:

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 will not show up in your Software Update list. To download the update get it directly from Apple’s website here.
UPDATE: according to Apple documentation the update should now show up in Software Update. See the link at the bottom of this post for more info.

I recommend (if you haven’t already) backing up all your data before applying this update. The update may tell you it’s not needed on your system, install or fail. In the first two cases you should be good to go but if the update fails, have the solid state drive replaced sooner rather than later.

    This has been the cause of massive data loss with our clients, even rendering the drive itself to be no good. The last client we had was able to get the drive replaced however the data on it was gone, wiped. Flash recovery is tough and expensive.

    So far I have seen the firmware update successfully complete about 80% of the time. A backup prior to attempting the update (or upgrade/update of any kind) is a must though.
