Apple has issued an EFI firmware update to its mid-2010 13-inch MacBook Pro which enables Lion Recovery over an Internet connection, allowing users to reinstall the latest OS X operating system onto their machine without the need for physical recovery media.
The version 2.5 firmware update is available to download now via Software Update on your Mac, weighing in at just 2.9 MB.
Lion Internet Recovery is a feature that made its debut alongside the Lion operating system on the new MacBook Air and Mac mini last July, and it allows users to connect to the Internet to download the Lion operating system for reinstallation. The feature later arrived on early-2011 MacBook Pro and iMac.
You may never need to use it, as Lion automatically creates a recovery partition when you install it. However, if you are unfortunate enough to experience problems with this, the Internet recovery option gives you something to fall back on, so it’s certainly worth installing.
