MacBook Air 2013 won’t start after software install
I have a 2013 MacBook Air on OSX El Capitan, tried to install macOS Sierra after clearing 11 GB storage. I read that I needed 8gb of storage. After running the installation package got an error message indicating there wasn’t enough space and the installation failed. Now when I try to restart I login but receive an error message. I would like go back and install my back up but I can’t access disk utility.
Attached are the error messages I get. Thanks for any help.
