When you turn on your Mac, it should display a gray screen as it searches for your startup drive. Once the drive is detected, you will see a blue screen as your Mac loads the boot information from your startup drive and then displays the desktop.

Some Mac users won’t actually see a blue or gray screen. With the advent of Retina displays and extended color spaces that the Mac now supports, the old blue and gray screens can appear much darker, almost black on Macs that have built-in displays, making it harder to discern which color the screen is.

If you’re using an external display, you should still be able to notice the difference between the gray and blue screens. We’re going to call the screen colors by their old, classic names, although for some Mac users, the difference will be very difficult to detect as the screens will just look either nearly black or black.

Regardless of the display type your Mac is using, that’s the normal chain of events, gray then blue, and something most of us don’t even think about. When I start my Mac each morning, I push the power button, then head to the kitchen to make coffee, fully expecting everything to work as it should. When I get back to my Mac, the desktop is waiting for me; I hardly ever see the gray screen or the blue screen. If either screen is waiting for me, then I know something is wrong. The Mac should always be ready before the coffee.

In this tip, we look at why a Mac may get stuck at the blue screen, and how to fix the problem.
