One of my goals for this blog is to make things that are difficult to find on the Internet less difficult to find, and one of those things is the key to hold in order to boot into the Apple Boot Camp menu at system startup. Finding that information once a year when I need it is always a many-step process, because the Apple documentation is wordy and doesn’t just come out and say:

Hold the Option key down.

Or Alt if it’s a PC keyboard.

There’s also the Boot Camp control panel, too, but obviously you did not, or could not, use it, which is why you were searching for the keystroke combination instead. Hopefully you didn’t have to endure too many answers to questions you didn’t ask before you found this.

Thank you for indulging me. Good day & good luck.
