Hello,

Got a MBP 13 from 2015. 256GB SSD, 16 GB RAM.

I was doing some work, when the computer suddenly rebooted (probably because I had postponed the latest OS update by an hour). However, the update failed because it could not find some system files. Tried to reboot again, but was still stuck there.

I Cmd-R:ed to restore with time machine. Restarted, but now I get the "no parking sign" on boot.

Disk utilities show the disk as grayed out, uninitialized. Can't put it back "on the desktop". Can't reinstall the system, because it doesn't find any drives.

Ran diagnostics (D on boot) that tells me there might be a problem with a memory module, and that I should take the computer to support. Is this a separate problem or does it include SSD-memory?

Tried to mount through terminal, but says the drive might be locked. When I try to unlock it, it says it's unencrypted (true). In any case, I don't manage to reinitialize the drive.

The SSD had been kind of sluggish since the month I got it. Programs took forever to start and file transfers were slow.

Is the SSD bust? A memory module? Can I do something about it? Data backup? Or should I just bring it to Apple?

Hi Guys, I finally found a fix for this issue.

So after waiting for almost 4 hours I gave up and force closed my Macbook Pro. I restarted it and the mac failed to boot up showing me some kernel commands. Got me really scared as I didn't take any backup of my files. These are the steps I took to successfully install High Sierra without losing any data. :)

1. Restart your mac in to Recovery Mode by holding down the Command (⌘) and R keys during startup.

2. Go to disk Utility and run the First Aid for Macintosh HD. Make sure your mac is connected to WIFI.

3. Restart again but this time in the Internet Recovery Mode by holding down Command (⌘) – Option (⌥) – R. It will take some time (10 minutes or so) to finish this process. When finished it will take you back to the normal recovery mode automatically.

4. Now Select Install a new copy of MAC OS. It will take 45 minutes to install here. After completing this process your MAC will restart and do the installation again for 45 minutes. ( I don't know why it happened two times but both the times it was real quick and it didn't freeze anywhere.)

I think the Internet recovery thing does something to fix this issue. My mac is now upgraded to High Sierra with all my files intact. :cool::cool:

Thanks, I have tried First Aid, but it returns an error and fails.
 
Formatted and reinstalled. Seems to work now at the cost of data loss. However, it's worrying that this happens. Many issues with macOS lately, programs that turn incompatible etc . Would likely hesitate to buy a mac again if I had to decide today. Photoshop and so on keep me on the platform as opposed to linux, and Windows 10 is the worst system ever.

Yu did not have a backup of your data?
 
I use a cloud solution for backup, but files generally get saved at intermittent locations before they are moved over there. Then there's always the fraction of misplaced files you forget you have, but remember when you need them.
