What Causes a Frozen Black Screen?

This problem can occur for a variety of reasons, but Mac computers most commonly display a black screen due to glitches with system upgrades or updates, or as a result of some type of problem while restarting from sleep or standby mode.

Sometimes, users note that their Mac displays a frozen black screen unexpectedly and for no apparent reason. It is not known exactly why this occurs, unfortunately. However, the method shown in this tutorial should also work to correct a black screen due to these unknown errors.

Well, it only feels that way because many still have got no clue for a possible reason. But if you’re familiar with the nature of Macs, you should know that the chances of fixing Mac issues are high.

Interestingly, what those MacBook Pro users are seeing is not really a gray screen. It could simply be a black screen with a built-in Retina display that appears gray during the initial startup phase. Most often, the problem is reported to appear after restarting a MacBook Pro. There are instances , though, when the gray screen appears with the Apple logo or a spinning globe sign.

Now, how do we fix this gray screen problem?
