Problem: I can’t turn my MacBook Air on
- First, check to see if your whole Mac has turned off, or just the screen. Is it still making noise? Does the Caps Lock key still light up? Does pushing the Power Button making a chiming noise? Then the issue is probably with your screen, and you should skip to the next problem on our list.
- If your MacBook is truly off and refuses to turn on, then check for any power problems. Cover the basics first. Is your battery charged? Does your laptop work when the power cord is plugged in? Does an extra power cord work? This indicates a problem with your battery or power cord. You should also disconnect everything (including your mouse, mobile devices, etc.) from your MacBook and see if that helps fix the problem.
- Reset your MacBook. You can reset simply by holding down the power button for at least ten seconds. Then push the power button again as you would normally to see if your Mac turns back on.
- Sometimes an important new upgrade like new memory can freeze your MacBook in permanent “uh-oh” mode. This is rare for the Air, which is built with a very compact design and resists most modding attempts. However, if you have added memory or other capabilities via external or internal work, note that removing upgrades may solve your problem. The access to Apple’s instructions may help here.

- If your screen is blank but your laptop appears to be working, try a hard reset to get back your video. Hold down the power button for at least ten seconds, then release it. Afterward, press the power button once as you normally would to turn your MacBook back on.
- If you are having problems with an external screen, try to update your MacBook with any external devices attached. With the cables in, go to the Dock or the Apple Menu in your upper left corner and select App Store. Once the App Store has opened, click on the Updates Install any updates you see for firmware, OS X, or other related MacBook operations.
- Make sure that any second screen adapters you are using are from Apple. MacBook Air doesn’t always play well with third party devices.

Problem: My MacBook Air’s battery won’t charge anymore
- The problem could also be with your adapter and charging cable. The MagSafe updates make this pretty confusing, because Apple really likes to change its charging cables. Basically, L-style and T-style adapters can work on the same computer, but MagSafe 2 connectors can’t work with those computers. However, T or L adapters can be used on MagSafe 2 ports, as long as you use an extra adapter to connect them. Apple has a visual guide if that was all very, very confusing.
- If you are using the right cable on the right MacBook Air, make sure that there is no damage to the adapter cable or the port. Try switching electrical outlets to make sure you are getting power. You should show also try unplugging your adapter for a minute, then plugging it back in again. If it magically starts charging after this break, then you have a lot of line noise in your electrical system. Try moving to a different building or turning off some appliances to see if this improves the problem.
Next: My battery is draining too quickly
Problem: My battery is draining too quickly
- Start by checking for updates on your Mac. Go to the Apple Menu and choose App Store. Visit the Updates tab, and apply all updates. Then restart your computer by going to the Apple Menu and choosing Restart. See if this makes a difference.
- Check out your apps. If you hover your cursor over your battery icon in OS X, you will see a list of applications that are currently using a great deal of power. You may find that an app constantly appears on the list. If so, shutting it down should help. Even Apple apps, like iTunes, can sometimes cause a problem.
- Reset your SMC. This may be particularly necessary if you recently downloaded an SMC (System Management Controller) update. Start by heading over to the Apple Menu and choosing to shut down the computer. Plug in your power adapter. Then find the left-side Shift key, the Control key, the Option key, and the power button: Press and hold them at the same time, then release. Wait for your computer to turn off, then turn it back on again.
Next: I think my Macbook Air is overheating
Problem: I think my Macbook Air is overheating
- As you’ve probably noticed, the Air was built to be extra-compact and light. One of the side effects is that there is only one vent, right at the base of the screen on the hinge. Always make sure that this vital vent has free access to the air. This means that using the MacBook Air with a second screen while the notebook is closed is a no-no.
- Look for any hidden or unexpected apps by visiting the Activity Monitor. This tool can be found in your Utilities The first tab is CPU, which will show you how much CPU time and energy each open app is taking up. If anything strange is using a lot of your CPU percentage, shut it down.
- If everything else fails, see if you can hear or see anything wrong with your fans. In addition to a physical check, it’s a good idea to run Apple Diagnostics (this works with newer Air computers). Head over to the Apple Menu and choose Shut Down. Once your Air is fully shut down, press the power button to start back up again, but then immediately press and hold the D key. Do this until the Apple Diagnostics check begins. This will include a progress bar and eventually a report.If the report finds an error, carefully read what it says and write down any error codes and instructions. Then click Restart to get back to OS X.
Next: I don’t have any sound on my MacBook Air
Problem: I don’t have any sound on my MacBook Air
- As with many problems, sometimes a full update can help solve the problem, especially if OS X itself needs an update. Head to your Apple Menu and select Software Update, then apply any available updates.
- You can also try resetting your PRAM/NVRAM, which affect your basic MacBook settings. Go to the Apple Menu and choose Shut Down. Then push the power button to start again: Immediately press the Command, Option, P and R keys at the same time. Hold down these keys until you hear a repeated start-up chime. FYI, this will typically remove any customized login settings you have set up.
- If you have an earlier MacBook Air (from early 2010 or before), we suggest taking your laptop to an Apple Store. In the first Air models, hinge problems could cause serious sound malfunctions. This can be repaired by technicians, but it may take some pricey replacements.
Next: My trackpad isn’t working properly
Problem: My trackpad isn’t working properly
- If you don’t use a mouse or are forced to use the trackpad out of necessity, you may have experienced an issue where it stops working or acts strangely, jumping around like it doesn’t know where your fingers are. You should first try cleaning and drying the trackpad to see if that helps. Moisture, grime, and dust can confuse it.
- Sometimes resetting your PRAM can help with trackpad issues (this also restarts your MacBook, which is another potential solution, so you can get two birds with this stone). Go to the Apple Menu and choose Shut Down. Then push the power button to start again: Immediately press the Command, Option, P and R keys at the same time. Hold down these keys until you hear a repeated start-up chime. FYI, this will typically remove any customized login settings you have set up.
- In addition to a physical check, it’s a good idea to run Apple Diagnostics (this works with newer Air computers). Head over to the Apple Menu and choose Shut Down. Once your Air is fully shut down, press the power button to start back up again, but then immediately press and hold the D key. Do this until the Apple Diagnostics check begins. This will include a progress bar and eventually a report: If the report finds an error, carefully read what it says and write down any error codes and instructions. Then click Restart to get back to OS X.
Next: My screen has frozen
Problem: An app has frozen
- If you can restart the app that you are working in, this may be able to solve the problem. If the app is completely unresponsive, find it in your Dock and right click on the icon to bring up the “Force Quit” option, which should be able to shut it down. Restart and see if this fixes the problem.
- If the app continues to freeze on you, check for an update. Go to the Apple Menu, choose the App Store, and head over to the Updates section to see all available updates. Choose to install any updates related to the app.
- When in doubt, you can always choose to shut down your MacBook entirely – one of your best options if the entire computer has frozen up. Hold the power button down for 10 seconds and then release it to force a shut down.
- If you have recently uploaded an OS X update, the app may no longer cooperate with the new version of your operating system. If this is the case, you may need to want for a patch to come out in a future update.
Next: I can’t use AirPrint
Problem: I can’t use AirPrint
- AirPrint can be tricky to use because it depends on third party devices, which may not always cooperate. Your first step should be updating your MacBook to make sure you have all the latest versions of software. Head over to the Apple Menu and choose Software Update to update everything all at once, or go to the App Store to choose individual updates.
- Look up your exact printer model online, preferably on the manufacturer’s website. If there are any firmware updates or warnings about AirPrint, you can find them there. Download and update as necessary. Remember that not all printers are compatible with AirPrint, even if they have wireless capabilities.
- Printers need to be connected directly – wirelessly – to AirPrint. If they are connected to an AirPort device instead, for example, that doesn’t mean they can automatically use AirPrint.
- If nothing else works, turn off your router, printer, and MacBook, then turn them all back on again, one at a time. It may be old-fashioned, but the old “turn it off, then on again,” solutions can still work.
Next: I don’t think my USB port is working anymore
Problem: I don’t think my USB port is working anymore
- First, do some basic hardware testing. Try switching to another USB device to see if it’s the port or the device. Try using your other USB port to see if it’s just one port or all of them. If only one port is misbehaving, there’s a good chance that there is some physical damage. Check to see if the port is loose, bent or otherwise damaged. If something is wrong with the port, take it to an Apple Store for a quick replacement.
- If all your ports are malfunctioning, try resetting your Mac SMC. Start by heading over to the Apple Menu and choosing to shut down the computer. Plug in your power adapter. Then choose the left-side Shift key, the Control key, the Option key, and the power button. Press and hold them at the same time, then release. Wait for your computer to turn off, then turn it back on again.
Next: My MacBook Air won’t shut down
Problem: My MacBook Air won’t shut down
- This is one of the odder problems that can occur to MacBooks, but you may find that nothing turns the laptop off – it just sits there humming instead of shutting down. Wait for 5 to 10 minutes to make sure that it really has a problem, then take a cursory look around OS X. Are there any warning signs, alerts, or active apps that need to be taken care of before you can shut down? Look for subtle signs too, like bouncing apps in the Dock, that show something is happening behind the scenes.
- If you have any apps open, check to see if they have become frozen. You can right-click on an app icon and choose to “Force Quit” to end the app and see if this restores functionality.
- If nothing is working, then you can force a total shutdown. Hold down your power button for at least 10 seconds to make your MacBook turn off. Note that this can be dangerous if your MacBook is trying to update, so make absolutely sure that everything is stuck and your MacBook isn’t just taking some personal update time.
Next: My Wi-Fi has stopped working
Problem: My Wi-Fi has stopped working
- Wi-Fi problems are common but notoriously hard to diagnose. While you’ve probably heard it before, we suggest you start by turning your router and computer off, then back on again, to reset your network and see if that helps.
- You should also download any updates for your MacBook to see if this makes your Wi-Fi smooth again. Head over to the Apple Menu and choose Software Updates to download any important OS X upgrades.
- If you have a dual-band router, try connecting to the 5GHz band. This band has a shorter range but is usually freer of interference, and can help fix problems with spotty Wi-Fi. If you have a different name for your 5GHz band, you will be able to find it in the Wi-Fi tab in the upper right of your OS X screen.
Next: FaceTime isn’t working
Problem: FaceTime isn’t working
- You should start by checking all your FaceTime settings. In FaceTime, head over to Preferences and see if FaceTime is verified or if it is “waiting for activation.” If it’s waiting, that means you may have gotten a new computer or email, and need to verify FaceTime through your email to proceed.
- You should also check other basic info in Preferences, such as the Date, the Time Zone, the phone number, and any other pertinent information.
- This is also a good time to try updating and restarting. Head over to the Apple Menu and go to Software Update to look for any available OS X updates. When completed, choosing Restart in the same menu.
Next: I’m seeing a lot of user interface lag
Problem: I’m seeing a lot of user interface lag
- Some users are experiencing UI lag in their new MacBook Airs – animations and graphics that get choppy when they start opening apps or resizing windows, etc. A restart may fix the problem.
- You should also make sure that any updates have been applied. You can always look for more updates by going to the Apple Menu and selecting Software Update.
- This lag issue seems to be related to Yosemite in some way. If you have data backups, you can try to re-download Yosemite (or the latest version, El Capitan) to see if this fixes the problem.
Next: Apps are crashing frequently
Problem: Apps are crashing frequently
- First, check for any app updates by heading to the Apple Menu, going to the App Store, and looking in the Updates It’s also a good idea to check out the general Software Update for any important OS X updates that could take care of the problem.
- If there are no updates, try un-installing the app and re-installing it via the App Store. See if the fresh version operates more reliably.
- If your Air feels very hot and has been working hard for a while, it could be overheating. Cut down on the number of apps running at the same time, and turn off your laptop to let it cool for half an hour or so.
