MacBook Air Black Screen: It Boots with Black Screen
MacBook Air Black Screen: Very rarely, your Mac may encounter some issue during system boot, like booting to a completely black screen. In some particularly rare cases, this situation can be interpret as a sign of a potential hardware problem. However, the issue relates more often to a software issue, which you can resolve with a few very simple troubleshooting steps. Thus, if your MacBook Air will not boot up past black screen and cursor, you should proceed as follows:
- Shut the MacBook Air down by holding the power button for ten seconds
- Restart the Mac and press shift at the same time until you see the progress bar start moving
- Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
- After a moment, you should see the spinning beach ball and the screen should then move on to something along the lines of “Completing OSX Installation”. Let it finish.
- Now the computer should go to its normal desktop and the issue should be fixed.
Don’t worry if the screen of your Mac goes pitch black during this process, just hit the space bar, because the screen is just sleeping.
If some features and apps don’t show up after the reboot, repeat the process.
Apparently this issue can be related to an automatic update that never quite got past the login screen.
People also suggest another way of fixing the issue, but don’t use it unless you are a computer guru:
- Back up all your date with Time Machine so once you restart the computer, you get everything reloaded. Remember that if you haven’t got all your files backed up then you might lose them
- Press command R as it starts up and keep holding until disk utility starts
- Go to disk utility and erase macintosh HD
- Go back to the menu and select install Mavericks OSX.
That can fix the issue. However we repeat that this method is recommended if you are an expert, because just installing Mavericks without erasing the old one won’t work.
Some experts suggest that if the above tricks fail, a PRAM reset can do the trick, as many of the computer gurus have tried this solution and can attest to it.
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 Air.
- As soon as you hear the boot chime, hold down the Command + Option + P + R keys together.
- As soon as you hear the boot sound again, the PRAM has been reset.
At this point let your Mac Air boot and load OS X again as usual, is it will no longer have the black display.
