Christian Zibreg ∙ Updated July 14, 2022

For those of you who have wondered about the many ways you can start up your Mac, here's a list of the Mac startup keyboard shortcuts you can invoke to access handy macOS features, which are only available at boot time.

Most of the time, your Mac just works—until it refuses to start up properly due to an unforeseen system error, a misbehaving app, a broken system component, and whatnot. Beyond system errors, different people have different needs when it comes to starting up their computers.

For example, you could be a pro user who dual boots between macOS and Windows on a daily basis. Others might wonder about booting a Mac from a disk other than their designated startup disk. Or perhaps you're looking to isolate the cause of a software issue in the macOS Safe Mode or boot straight into Recovery OS as the last option?

Anthony Bouchard ∙ Updated October 10, 2023

RGB, otherwise known as red/green/blue, is a color identification method used by digital computer monitors. Every color gets its own RGB value, and this is because a mixture of those three colors makes up the color you're looking at.

RGB values may be used for a variety of reasons, but mostly for those that do a lot of photo editing or who may be tinkering with graphics or web design.

A little-known feature of your Mac is that its operating system comes with a meter that can identify the RGB color of any single pixel on your screen, and in this tutorial, we'll show you just how that's done.
