Reinstall Mac OS X Mountain Lion before selling a Mac I want to sell my laptop (Macbook Pro late 2011).
I have erased my disk drive but it seems that I cannot reinstall Mac OS without an Apple ID.
At the origin my mac was shipped with Lion, I have upgraded to Mountain Lion and now my recovery partition contain the installer for Mountain Lion. When I try to reinstall Mac, it asks for my apple ID. Since I want to sell it, I don't want to put any of my information in it.
How do you do that?
If you happen to already have an installable copy of Lion or Mountain Lion,


back up your personal data
make a bootable thumb drive to install from
boot from the thumb drive
select Disk Utility
repartition and reformat your drive
there should be an arrow to skip the Apple ID entry and continue the install.


Either of the two ways should get you a virgin install.

The other way is to do a recovery boot by holding down COMMAND-R when powering on before your Mac chimes. It will be slow since all files load from Apple's servers. Follow the six steps above for a clean install.
