My Macbook pro 2011 won't boot completely anymore (can't open it). In the recovery mode, I can see my disk (SSD) but when I want to download the last IOS on my mac, it seems my computer can't find my SSD.

Can anyone help me found out if my computer is retrievable and if not, is there a way I can recover my files from my SSD?

Thank you very much, Chloe

  • I would suggest taking it to a repair shop. Don't try to DIY this task.

  • There were 6 different MacBook Pro notebooks for 2011, which one exactly do you have and what version of macOS are you running? Nov 2, 2020 at 19:08
  • A1278 (EMC 2554) sorry, not 2011, but mid 2012. I use to have the last version of OS. But not it is asking me to download Mountain Lion Nov 2, 2020 at 19:29
  • Are you able to boot it from macOS Recovery from the internal SSD, or are you using Internet Recovery or a USB Installer? If you are using Internet Recovery or a USB Installer to boot it and it can not see the SSD, then you will not be able to do anything other then replacing the SSD. Nov 2, 2020 at 20:22

There are two possibilities:

1. The SATA cable connecting your SSD to the Mac is intermittently failing. This is a common problem in MBPs of that vintage.

The good news is that this means the data itself on the drive is ok, and the internal cable just needs replacing. Alternatively, you could get an external USB enclosure (a box with a USB cable), and put the SSD in there. You may want to get a repair shop to do this.

2. The drive itself has failed in some way.

If this is case, then it is very unlikely that your data can be recovered.

Backups of data are essential to prevent data loss from drive failure. This is why macOS has Time Machine.
