My friend has a Mac book pro. I'm afraid I know nothing else about it.

For reasons unknown, and I dare not ask, she decided to rub a magnet over it, beside the touch pad.

She heard a strange noise, and powered it off. Then, when turning on, she just saw a question mark on the screen.

I'm guessing she's either wiped or destroyed the SSD. However, she's asked me to restore it and I know nothing about this.

Whilst my research shows me that files may have been synced to the Cloud (the cloud? Surely they mean to a server, using the technologies which have been available for years). But it doesn't state if the OS is backed up.

The computer didn't come with any discs.

On a Windows PC (which I have little experience with), I know that some times the OS isn't included but the serial number is, so you can get an ISO and re-install it that way.

Other PC's include the installation files on a partitioned hard drive.

My question is, is there a uniformed way Apple supply the OS with Mac products (unlike PC's)? If so, what is it?

  • simple try ...push power on and hold two keys the cmd and the letter r that will bring up the Recovery. – Ruskes May 8 '14 at 7:48
  • That is great. I did look for things like this - a quick search shows this is a recovery partition. I'd be able to take it from there. @Buscar웃, feel free to move to an answer – MyDaftQuestions May 8 '14 at 7:51

The question mark comes up when the start up files have been messed up.

I do not know if you can repair the Magnet damage but you can try to restore.

Mac's have a Restore function build in (or online)

To access start computer and hold cmd-r

that will bring up the restore menu.

Depending on your computer model you might have the Internet restore option.

The sound you heard was the forced computer shut down.


Restore OSX using OSX Recovery. To do so, hold CMD+R at the boot chime. If the recovery partition has been wiped as well, you will need to restore using Internet Recovery: CMD+ OPT+ R at the chime.

From either, select "Reinstall OSX" from the pane you are presented with.
