EFI Firmware Updated on Mac Mini, iMac, MacBook Air, and Pro

Apple today released EFI firmware updates for their Mac mini (mid 2011), iMac (early 2011), MacBook Air (mid 2011), and MacBook Pro (early and late 2011) computers. The updates are meant to fix some issues that may prevent complete stability on each of these devices and Apple highly recommends that all users update to the new EFI firmware at once.

This update improves the reliability of booting from the network, addresses an issue that can prevent HDCP authentication after a reboot, and resolves an issue with boot device selection when a USB storage device is hot-plugged.

When updating, please remember that you should keep your computer connected to power, even if the battery is at 100 percent. This will ensure that the process goes smoothly.

Apple last issued an update for EFI firmware to their iMac (mid 2010), MacBook Air (late 2010), and MacBook Pro (early 2010) computers earlier this month. The update added Lion Internet Recovery to all of the aforementioned devices in order to make it easier for users to restore their computers to factory settings in the case of a data loss or crash. Before that, Lion Internet Recovery was solely available to Macs that were released alongside the new operating system last summer.
