Problem: My MacBook Air won’t shut down Solution: Look for apps and services that require your attention: Nothing turns the laptop off — it just sits there humming instead of shutting down. Sorry Dan, altering the date via terminal was a lost of time. It didn't work for me. What did work was using a bootable usb. In a friend's Mac, download the desired OS installer (High Sierra in my case for my MacBook Pro Late 2011 - google 'How to Download a Full macOS High Sierra Installer App') and create the bootable USB, HDD or even SSD with Disk Creator (2 steps very friendly freeware.

Many MacBook Air users are having issues with their keyboard. Their MacBook Air keyboard isn’t responding properly or has become totally unresponsive.

This is a very annoying issue. You can’t use your MacBook Air if its keyboard is not working properly. But don’t worry. Your keyboard can still be fixed…

Try these fixes

You don’t have to try them all; just work your way down the list until you find the one that works for you.

Method 1: Update your macOS

Your keyboard may not be working because your operating system is not up to date. You should update the macOS on your MacBook Air to see if that’s the case for you. To update your system:

1) Click App Store.

2) Click Updates. Then if there is any system update available, click UPDATE next to this update.


3) Wait for the update process to complete.

Method 2: Reset the SMC

The SMC (System Management Controller) on your MacBook Air manages the functioning of your keyboard and other hardware components. You should try resetting the SMC to see if this fixes your keyboard.

Note that only Intel-based Mac computers have an SMC.

1) Shut down your MacBook Air.

2) Press the Shift, Control and Option keys on the left side on your keyboard and the Power buttons at the same time. Then hold them for 10 seconds.

3) Turn on your MacBook Air.

Check to see if this fixes your keyboard.

Method 3: Clean system junk

Perhaps your MacBook Air keyboard is not responding properly because of the software conflicts caused by your system junk. To try fixing your keyboard issue, you should clean up your macOS. If you want to do it quickly and easily, you can use MacClean.

MacClean is a cleaning utility that can help you clean your macOS. It will scan your system and identify the junk files or caches that may slow down your Mac computer. You will remove those files very quickly with this program. It takes only a few clicks to clean your system:

1)Download and install MacClean.

2) Run MacClean.

3) Click System Junk, then click the Scan button. MacClean will then scan your MacBook Air and find all your junk file.

4) Click Clean to clean all your system junk files (this requires the registered version, you’ll be prompted to register your program when you click the Clean button).

Method 4: Clean your keyboard

Debris in your keyboard can stop your MacBook Air keyboard from working properly. You should make sure your keyboard is clean.

To clean your keyboard:

1) Shut down your MacBook Air.

2) Clean the keyboard with a cleaning tool, such as a can of compressed air.

After cleaning the keyboard, turn on your notebook and see if this works for you.

Method 5: Have your MacBook Air serviced

Your MacBook Air keyboard may also fail to work if you are having hardware issues with your notebook — perhaps you’re having a swollen battery, a chip that communicates with your keyboard is not working properly, or one of your keyboard cable is broken. If you don’t have the time, patience or skills to fix it yourself, you should have your notebook serviced. Bring your MacBook Air to Apple or any authorized service provider and ask them for advice.

MacBook Air Black Screen

MacBook Air Black Screen: It Boots with Black Screen

MacBook Air Black Screen: Very rarely, your Mac may encounter some issue during the system boot, like booting to a completely black screen. In some particularly rare cases, this situation can be interpreted as a sign of a potential hardware issue. Fortunately, there are a few very simple troubleshooting steps to try to fix it. So, 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. Type your password and then hit Enter again.
  • 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”. Allow it to 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 (Since the screen can go to sleep during this time.)

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.

There is also another way of fixing the issue, but we don’t recommend it unless you are a computer guru:

  • Back up all your date with Time Machine, so once you restart the computer, you can get everything reloaded. Remember that if you haven’t backed up all your files, there’s a good chance you will lose them.
  • Press command R as it starts up and keep holding down until disk utility starts.
  • Go to disk utility and click Erase Macintosh HD.
  • Go back to the menu and select install Mavericks OSX.

Just installing Mavericks without erasing the old one won’t work, so only try this method if you know what you are doing with your computer.

Some experts suggest that if the above tricks fail, a PRAM reset can do the trick. Many of the computer gurus have tried this solution and can attest to it.
As a potential solution to the black screen on boot issue, try this while restarting. (It is very 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. It will no longer have the black display!
