Macbook Pro Won T Turn On Black Screen

Picture of Macbook Pro Won T Turn On Black Screen

Rarely, a Mac may encounter some peculiar issue during system boot that can cause quite a bit of panic, like booting to a completely black screen. It would be easy to interpret that as a potential hardware problem, and in some particularly rare situations that may be the case, but it’s more often a software issue that can be resolved with some simple troubleshooting steps. Case in point; one of our readers experience with his MacBook Pro, which out of the blue rebooted to a completely dark screen.

Though it’s rare, we figured this would be a good opportunity to share three potential solutions to this problem, and similar issues, should you encounter a dark screen on system start. First, Reset the System Management Controller to Fix the Black Display on Boot The first thing you’ll want to do resolve nearly every power related issue on a Mac is to reset the SMC, or System Management Controller.

This will dump and reset settings for anything power management related, and is long known to resolve problems with things like fans, heat, sleeping problems, and of course, display issues. On any modern MacBook Pro or MacBook Air with a built-in battery, which is just a bout all of them nowadays, this is how you do that: Shut down the Mac and connect it to your MagSafe adapter and a wall outlet as usual Hold down the Shift+Control+Option+Power button at the same time for a few seconds Release all keys at the same time, then boot the Mac as usual Older Macs can find directions here for the same process on their machines, it’s slightly different if you can take out the battery.

When the Mac boots, hopefully the black screen has gone away and you’re back to normal, but if it doesn’t… reader Nathan D. wrote in with the next tip. Second, Try a Keypress Sequence to Ditch the Black Screen Regular readers may recall that we covered some OS X keyboard shortcuts for the Shutdown, Sleep, and Restart controls of just about every Mac, and this little key press sequence takes advantage of those.

Oddly enough, it seems to work to resolve some of the mystery Mac booting into black screen issues. Here’s the precise sequence to follow: Press the Power / OFF button once – this will bring up the dialog box which you can’t see Press the “S” button – this is the shortcut to sleep the Mac Hold down the Power button until a hard shut down is forced Wait about 15 seconds, then hit the Power button again to turn it back on This key press solution was discovered by reader Nathan D.

, who found it tucked away on MacRumors Forums, and it has worked for several other commenters there as well. Some other users on the MR forums suggest that resetting PRAM helped them too, but most power issues are resolved by the SMC reset. Try a PRAM Reset to Resolve the Black Boot Display If the above two tricks failed, a PRAM reset can often do the trick, as many of the commenters on this article can attest to.

As a potential solution to the black screen on boot, this is done upon restarting the Mac similar to an SMC reset: Reboot the Mac and as soon as you hear the boot chime, hold down the Command+Option+P+R keys together When you hear the boot sound again, the PRAM has been reset so let the Mac boot again as usual At this point your Mac should boot again as usual and no longer have the black display, loading Mac OS or Mac OS X as usual.

Finally; Enter Password, Hit Return Some users in our comments report an interesting alternative finding if they hit the black screen on boot; if they enter their regular login password and hit the Enter/Return key, the Mac boots up as usual and they’re good to go. Try this out, it might work for you: When the Mac boots into the black screen, enter the password you’d use to login to the Mac as usual Hit the Return key If this works, you’ll know rather quickly because the black screen will give way to the regular Mac OS desktop.

Did one of these solutions work to get past the black screen on Mac boot for you? If you happen to run into this unusual issue with your Mac, let us know how you resolved it, and if the above tips worked for your MacBook, MacBook Pro, MacBook Air, and whichever Pro or Air model it may be. Related

The key function of contemporary computer system monitor savers is entertainment and from time to time even, safety. Nevertheless, they were in the beginning created to avert phosphor burn-in on plasma personal computer displays as well as CRT units. Monitor savers assisted to circumvent these damaging consequences by instantly altering the photographs in the event the computer wasn't getting used.

Allow me to notify you of a brain boosting system I'd stumbled upon soon after loading an exceptionally huge number of illustrations or photos into My Pictures file, which was mechanically hooked, potentially like your pc established up, to my display screen saver plan. Right after sitting and viewing it at some point, I noted the way it spurred on my brain and amplified my spatial reasoning ahead of planning sessions. It genuinely assisted and i was stunned.

Silly question but I've got to ask. :-)Did the Macbook in question come with 10.6.x or earlier?  If so, did it have a firmware upgrade or two?  If not, with which O/S did it come originally?Finally, what is the exact version of 10.6 listed on the disk (10.6, 10.6.3, 10.6.4, 10.6.8, ...)?I ask because it is possible that a sufficiently new Mac or one that has gone through firmware upgrades might not boot with a 10.6.0 disk.  However, a newer version of the disk might work.
