As we reported last week, there were numerous problems with the MacBook Air firmware update released earlier in the week. Users reported symptoms as innocuous as the update simply not being applied, to preventing the laptop from rebooting. In most cases, performing multiple SMC resets on the computer fixed the booting problem, but the update was still not installed. A few users found that even though the System Information application reported that the firmware was not updated, afterwards their MacBook Airs began suffering some of the problems that the 2.9 update was supposed to fix. Some of the symptoms included trouble reconnecting to wifi networks, fans unnecessarily running at full speed, and issues with sleeping and waking the computer.
Let than a day after the reports began flooding in, Apple removed the update from the App Store and users were no longer getting prompted to install it. As of today, a newly numbered 2.9.1 update can be found appearing in the App Store under Updates. Owners are cautioned to hold off on applying the new update, unless necessary, until reports come back that the install is working correctly. We will keep you updated as reports come in and the situation develops.
