factory reset to get a clean macbook Pro

Okay so here's what you do if you have newer Macs like me to get to a brand new condition. I did it with mine a few times because when I got it new about two weeks ago I screwed up and wanted to start from new.

Here's the steps for restoring your Mac to factory.

1. Backup all your data, either manually or use Time Machine

2. Shut down your Mac

3. Press, Command+R on your keyboard, press and hold

4. Power on your Mac and keep command+R and hold until you get the OS X utilities screen, this is a recovery partition which ou will use to erase and reinstall OS X.

5. To erase the current data, go to disk utility, select Macintosh HD which is default and click on erase tab.

6. Click erase, making sure that it is Mac OS extended journaled

7. Quit disk utility and it will take you to the OS X utilities main windows, this time click reinstall OS X.

You will need internet connection to download OS X Yosemite from Apple, now follow the on-screen instructions, it's pretty much self explanatory.

After that you will get a shiny new factory OS X Yosemite.

Good Luck

It usually saves all the network settings and import into system. So it will automatically keep you connected during the restore. If it's not connecting, it will prompt you for WI-Fi. You can check by holding down Option key and check and see if you are connected.

If for some reason when you choose to sell, trade, or recycle to other owner your Mac

that shipped with a built-in system, the use of Recovery may be able to re-install the

original system it had in it when new; or one that is not associated with your AppleID.

That aspect of removing your AppleID from the computer or iDevice prior to a new

owner taking possession, lets the product function and does not brick it later...

Also, if you had a computer that shipped with Mavericks 10.9, and you may have

some software that worked better there, you may be able to go back; or install it

from the recovery mode and put it into a different partition on a hard disk drive.

However there are utilities and processes that may remove all residual parts of an

older system; in some instances, an older 'original system' could be lost.

So the process with an older model that had a system install-restore DVD disc set

would be different, and in some ways better for those with an offline archive from

which to restore or renew the system. A clean copy of the installed system, for your

own use, could be created on a separate externally enclosed hard drive of suitable

specification that could support bootable clones. If set up ahead of time.

In any event, the step-by-step is covered in the link above as well as it was

in the link content to thesafemac site, where there is no install DVD involved.

The internet access is part of the setup. An existing location can be used.

Good luck & happy computing! 🙂
