When Mac OS X Lion was released, the ability to restore from a recovery via internet connection was seen as its coolest feature. Unfortunately, this was not so for the MacBook Pro 13 inch models from mid-2010.
However, now Apple has changed that with an update to Extensible Firmware Interface (EFI). This update makes it possible for notebooks, like many other Mac OS X Lion-supported computers, to have this internet recovery feature. For those who are not aware, EFI controls the low-level hardware actions. It can be thought of as basically the Mac version of BIOS – just to keep things simple and easy to understand.
Now the internet recovery feature from Mac OS X Lion is incredibly handy. If something goes completely wrong with your drive(s) and you need to do a complete reinstall of Mac OS X Lion, then you can do so directly from Apple’s online servers through EFI – that is, when you hold down the option key at boot-up. You will find all of the drives on your computer there, including the recovery option. The recovery option would download and install Mac OS X Lion all over again for you.
All of the newer Macs have Mac OS X Lion internet recovery. That includes iMac, Mac Mini, MacBook Air, and MacBook Pro. Not all Macs have the feature. The Macs without this feature are stuck with using USB flash drives and creating their own hardware-based bootable drives.
This can cause you inconvenience in both aspects. If you rely on the internet-based recovery, then you can only do so if you have the internet connection needed. If you rely on the USB flash drive-based recovery, then you have spend money on one or more flash drives, depending on how much data do you intend to save. So neither of the two options are without their prerequisites. However, the internet-based recovery is much more user-friendly and automatic.
If you have a 13 inch MacBook Pro from 2010 (Intel Core 2 Duo), then this update would be helpful to you if you run Mac OS X Lion on it. It could get you out of a rough spot in the future. The size of this update is 2.9MB for download.
