I started the day by receiving the following message, spontaneously:

your computer restarted because of a problem. Press a key or wait a few minutes to continue starting up.

So I upgraded High Sierra. But the problem continued, I kept getting the message above.

So I uninstalled all my apps which came from outside the Apple store. Throughout this process, the problem continued.

Finally, I thought I might as well just reinstall everything. After all, everything I have is in one cloud or another anyway. I started the computer in recovery mode and just wiped the main drive. Easy! And very possibly stupid.

When I went to install High Sierra again, I got the error, though I tried twice in a row.

could not create reboot volume ...

Yikes. So I started her up again, CMD R, and a little globe starts spinning. Eventually, I am given the option to install OS X Yosemite. Ok, fine, better than nothing.... but then when it says select the disk you want, there are no options... just the external USB drive...

When I go to disk utility, I see “500.28 GB APPLE SSD...” with a little grey “disk0s2” beneath it.

What should I do now? I feel WAAAY over my head here...

    This is the equivalent of feeling a pain in your chest and immediately going straight for the heart transplant. I am hoping that somewhere in this you backed up you data. Now, the first question is, what type (model) of Mac do you have? Secondly, when you boot from Install/Recovery, go into Terminal and type the following diskutil list and post the output.

    Yes, it’s a hell of a Monday already! I have a MacBook Pro. But, I can’t easily post the output. One sec while I find a solution, maybe take a pho

Your solution is to destroy and recreate a clean partition then perform a full re-installation

  1. Issue the command

    diskutil partitionDisk disk0 1 GPT HFS+ MacHD 100%

    This command will create a single GPT partition formatted for HFS+ with a name of MacHD. You can change the name if you like, but use quotes if you use a name with spaces like "Macintosh HD".

  2. Install your macOS as normal. You can enable Journaling and/or FileValut at this point.


Having a bunch of kernel panics is not normal. While it can be a software problem, it often is a hardware problem.

First, run Apple Diagnostics or Apple Hardware Test. If no errors are reported, start from Internet Recovery, create a new partition on your SSD, and reinstall the OS.
