How do wipe and reset your Macbook Pro Retina to Factory.

You need to boot the system to the Recovery HD. Hold down Command+r key at startup. Open Disk Utility and erase the Macintosh HD. Exit out of DU and select Reinstall Mac OS X. Select Macintosh HD as the place to install to and wait for Lion to be downloaded from the net. The computer will restart when the download is finshed and the install will start.

Mac os extended journaled is what you should select.

that's normal, you've got a flash drive which is quite fast.

The erase only took about 10 seconds. Is that normal?

Yes, as it can't be Secure Erased like hard drives can, thus the storage is simply given instructions that all files are now able to be overwritten which is extremely fast, even on hard drives.

You can't secure erase solid state drives as that would wear them out prematurely, so what's on there can be recovered unless the entire drive is filled with new data. You can use Filevault, however it's basically worthless as the password has to be given for repair or easily changed.

How do I securely delete data from the machine?

Yes Mac Extended (Journaled) is what you want. But in all honesty that should be the default, IE what is already listed without doing the drop down.

ds store i was looking at your How do I securely delete data from the machine? and im trying to wipe evering thing from my harddrive like if i was selling it, when im in the disk utility i dont have to erase i can only erase free space do i have to erase the free space first then i can erase the rest or is there a problem with my computer?

Are you booting to the Recovery HD partition? That is what you have to do to Erase the Macintosh HD partition.

At startup hold down the Command+r keys.

will my mac ask for my appstore password again or will I have to buy OSX mountain lion another time?

It will ask for the mac app store password again

If i starts with mountain lion i don't need to enter app store code well?

No if the system came with Mt lion you would not need to enter any code to re-install Mt Lion.

The same is true if it came with Lion and you never upgraded to Mt Lion.

Only if your system came with Lion (or a previous version of OS X) and you upgraded to Mt Lion (or it came with Snow Leopard and you upgraded to Lion) would you then need to enter your Apple ID (The same one used to buy Lion or Mt Lion) during the re-install.

Not sure why Xolesk replied to a 6 month old thread.
