How to restore MacBook Air to factory condition

I bought MacBook Air in August and sold it a month ago on eBay. At the time, I was planning on using it during my commute and for school. Though my commute is still there, there is no school on the horizon, at least for the time being. The machine was too sexy for dust and that’s why I sold it.

I got a little frustrated when I wasn’t able to figure out how to restore MacBook Air to factory condition. After spending over 1-hour reading support forums and numerous blogs, finally, I was able to figure it out.

In the end, I felt that it wasn’t really that complicated and Mac geeks seem to think that Command Line is a piece of cake for an average person. Trust me, it’s not.

Here’s my simple 5 step guide to restoring MacBook Air (13-inch, Mid 2011) to factory condition:

1) Restart your computer while holding down the Command and R key. The Mac OS X Utilities pane appears.

This screen allows you to run Disk Utility to erase your hard drive and reinstall a fresh copy of Mac OS X Lion.

2) Click on Disk Utility, select the disk on the left, select Mac OS Extended (Journaled) from the pop-up menu and then click Erase. Your screen should look something like this:

3) After the disk is erased, select Disk Utility and then Quit Disk Utility.

4) Make sure you are connected to the Internet through WiFi. You have to be connected in order to re-install Mac OS.

5) In the Mac OS X Utilities pane, select Reinstall Mac OS X and click Continue.

If all goes well, you will have a clean install of Max OS X. Your MacBook is now officially restored to factory condition and you didn’t have to go through the command line.
