Format MacBook Pro

I know you marked Clinton's post as correct, but if you don't first delete the recovery partition currently on your computer, it will reinstall Mountain Lion, & you cannot sell your computer with Mountain Lion on it.

What version of OS X did your computer originally ship with?

Did you upgrade to Mountain Lion?

Ignore the above post until you answer these questions.

As wjosten states following what Clifton posted as Kappy's advice will NOT reinstall Lion. That will reinstall Mt Lion and that Mac can NOT be sold with Mt Lion installed.

DO NOT FOLLOW THAT ADVICE. IT IS WRONG!!!!!!!!!!!!

You have to use Internet Recovery to reinstall Lion.

At boot hold down the Command+Option+r keys until you see a spinning Globe in the center of the screen.

Have the computer WIRED to your internet router, Ethernet cable from computer to router.

Then once that screen loads you hace to Repartition the drive as ONE partition. that will remove all traces of Mt Lion from the system. Then you reinstall Mac OS X and that will reinstall Lion on the system.

Hi, do I need to deauthorize my macbook pro if I'm formatting but not selling? I just want to clean it and start fresh.

No, no need to deaothorize if you're keeping the machine.
