Installed new os and now won't restart
I Just installed the latest os and now my laptop won't restart. All I get is a file folder icon with a question mark in it.
MacBook Air (13-inch Mid 2013), El capitain
The question mark means your Mac can't locate a system folder to boot from.
Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
