It would be easy to interpret that as a open in browser PRO version Are you a developer? Try out the HTML to PDF API pdfcrowd.com 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: OSXDaily 1. Shut down the Mac and connect it to your MagSafe adapter and a wall outlet as usual Follow +1 2. Hold down the Shift+Control+Option+Power button at the same time for a few seconds + 8,218 3. Release all keys at the same time, then boot the Mac as usual open in browser PRO version Are you a developer? Try out the HTML to PDF API pdfcrowd.com 3. 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: 1. Press the Power / OFF button once – this will bring up the dialog box which you can’t see 2. Press the “S” button – this is the shortcut to sleep the Mac 3. Hold down the Power button until a hard shut down is forced 4. 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 open in browser PRO version Are you a developer? Try out the HTML to PDF API pdfcrowd.com 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: 1. Reboot the Mac and as soon as you hear the boot chime, hold down the Command+Option+P+R keys together 2. 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: 1. When the Mac boots into the black screen, enter the password you’d use to login to the Mac as usual 2. 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. open in browser PRO version Are you a developer?

It can be the simplest things some times. And cats like macs by the way Reply Joe says: February 25, 2015 at 3:21 pm None of the three solutions worked for me, but I found a solution for my case. I tried hooking up an external monitor and Windows 7 worked fine on the external monitor but still would not come up on the Macbook Air screen (the screen also worked fine when running the Mac OS). Using the external monitor, I searched around the control panel for the brightness control, and it was set all the way to the left. I moved it toward the middle and it worked. Note that you have to do this separately for both plugged in and not plugged in options. That solved the issue, but the brightness and volume keys still did not work. I went to the Bootcamp Control panel (accessed by clicking the grey diamond Bootcamp icon in the pop up arrow on the bottom task bar), clicked through to get to the keyboard open in browser PRO version Are you a developer? Try out the HTML to PDF API pdfcrowd.com tab, and there was a box that was checked stating, “Use all F1, F2, etc. keys as standard function keys.” I unchecked the box, and the keyboard controls returned to normal. Not sure exactly how this happened, although my son turned the brightness way, way down using the keys in order to listen to something on my computer overnight, and this happened the next day. May or may not be related, but I would guess yes. Hope this helps someone as I did not see this solution anywhere else and it took me several days of experimenting to find it.

I was in desperate need of the machine this weekend, and I had no time to return to an Apple Store. Thanks again. Reply B says: December 15, 2015 at 4:02 pm Third option worked for me too. Thanks to whoever the credit is due!!! Reply Edward says: open in browser PRO version Are you a developer?

Wow-thanks so much! Christine says: November 17, 2016 at 4:11 am Thanks so much – third option finally worked on second try. Thankyou Thankyou Thankyou!!! Reply Becky Parker says: December 14, 2016 at 12:36 pm Yes, the 3rd one worked for me, too. Twice now it has worked. Thanks for this great trick as it saved me money to send the Mac Pro back to Apple for no idea how long.
