I bought a new Macbook Pro today OS Sierra mid 2015 model as an ex display from a reputable shop.

However the shops passwords were on there, I contacted them and they said just reboot the mac.

So i followed the steps online and I accidentally deleted my hard rive and then it reinstalled an old version of MAC OS X El Captain
but then it was locked so I followed your steps on here to unlock it and then it took me through all the steps to install this older version Mac OS X but then when i went to finish the installation it says sorry it can be installed as a new version it already on the system.

However on disk utilities it just says OX Base system on the hard drive settings. Please help I would so appreciate it.
Thanks

A bit confused about your post. Also this is the iMac forum not MacBook Pro forum...Regardless, I hope my advice below helps you out.


At this point, my advice to you is to start completely from scratch. Hold Option-Command-R immediately after powering up, continue holding until it launches apple internet recovery (may prompt you to connect to wifi or just hardwire to ethernet if you can). You can let go after you either see internet prompt or Apple logo. Once recovery starts, format the drive in disk utility and reinstall the OS. Please note that internet recovery will likely restore the computer to whatever OS it first shipped with as new, you can always upgrade via the App Store for free. I wouldn't recommend using the built in recovery partition as I can't be clear on what this 'shop' did to the computer. Best to start fresh from Apple.

Follow these steps: https://support.apple.com/en-us/HT201314

The other options are more complicated and would require you to use another Mac to create a USB installer. Internet recovery sounds like the easiest solution for you at this time.
