Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

You may not install this volume because the computer is missing a firmware partition

I asked this already. Someone told me to reinstall the OS, I did that, and it worked, but when I go to upgrade to High Sierra it still does not work. Can anyone help?!?!?


This is crazy, I though Apple made things simple?!
