What to do when keyboard commands don’t work at startup on your Mac<article>

A minor puzzle arrived from a reader who was trying to choose his boot drive by holding down the Option key at startup. OS X has a variety of keyboard combinations you can press to invoke different modes on startup, like Command-R for OS X Recovery, which boots from a special partition and lets you run Disk Utility and Terminal. (Apple
has a list of all commands; it’s surprisingly long.)</p><p>
But it wasn’t working for said reader. He wondered if some IT person in his firm had managed to install a bypass, but I had another idea. OS X doesn’t always recognize keyboards at boot that it does when you reach the login screen. So you can pointlessly hold down a key or a combination of keys, and nothing happens at startup, but then you have full keyboard access when it’s time to enter a password or use arrow keys or the Tab key to move around the login screen.</p><p class="jumpTag"><a href="/article/3106146/macs/what-to-do-when-keyboard-commands-dont-work-at-startup-on-your-mac.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
