Apple’s MacBook Pro and MacBook Air have set new standards in terms of efficiency and performance. Even then, they’re machines at the end of the day. No matter if you’re using the latest model or an older one, sometimes things go wrong. The following guide will help you quickly get things back on track again. 

1. The start-up shows a black screen 

A failed Mac start-up can show a few different colored screens, and they all have different meanings. If you see a blue or black screen, it is a sign that your Mac has frozen while loading a problematic login function or app. Press the power button for six seconds to restart your computer and if that doesn’t work, boot your system in Safe Mode. Then, remove the troublesome login items and apps that might not be compatible with your macOS version. 

2. Cannot turn on your MacBook Air/Pro

Here are a few things you can do if you cannot turn on your Mac:

• Check for power issues by ensuring the battery or the power cord is functioning correctly. If the problem is with either, disconnect all the peripherals like a mouse and other mobile devices and see if it is fixed. 
• Ensure the screen is not turned off. If the screen is fine and your Mac won’t start, try a hard restart by holding down the power button for ten seconds, letting it go, and pushing it again to see if your system turns on. 
• If you have recently added memory or other capabilities, it may freeze your laptop. Remove the upgrades and see if the problem gets solved. 

3. Error code 43

Error code 43 typically occurs on a Mac when users try to move files or delete them, and the system fails to locate the file in question. Therefore, the requested action is not completed. While this error can occur anywhere, it is commonly observed when moving files from the USB drive. 

If you’re facing this error, you can scan the hard drive and automatically repair the issue using the built-in Disk Utility application. The solution is perfect for situations when the error code 43 has been caused due to hard disk corruption. 

Firmware issues related to Mac’s NVRAM or PRAM can also cause error 43 on Mac, and to solve it, you need to reset NVRAM or PRAM. For more ways to fix the error code 43, click here https://setapp.com/how-to/fix-error-43-on-mac.

4. The screen isn’t working 

If your MacBook Air or Pro screen isn’t working, you can try doing a hard restart. Hold down the power button for ten seconds and let your system rest for a few seconds. After that, press the power button again and see if the screen turns on. 

When facing issues with the external display, you can update your MacBook. While the cable is still attached, go to System Preferences on the Dock > select Software Update. 

Also, always use Apple adapters because the MacBook Air doesn’t play well with third-party second screen adapters. If you are using any third-party adapters, that’s your culprit. 

5. Getting overheated 

Even though Apple’s Mac products are built to perform exceptionally, they get overheated sometimes. Running multiple apps simultaneously or using graphics-intensive apps might be the reason behind your Mac getting overheated. The problem can be solved quickly by shutting down your system and letting it rest for a few minutes. However, if your computer keeps getting overheated, here are a few things you can do:

• Look for unexpected or hidden applications that might be running in the background without your knowledge. On the menu bar, click Go > select Utilities > open Activity Monitor > go through the CPU usage tab. If you find apps consuming a lot of CPU memory and you don’t’ need them, click the Stop or X button. 
• Check if the fan is functioning correctly by launching Apple Diagnostics. You need to turn your computer off and turn it on while pressing D. Your Mac will automatically test the hardware and inform you if the fan is broken. If the fan is not broken, you can check the vent and ensure there are no dust and debris. The vent must be clean so that there’s ample circulation of air. 

Using the troubleshooting tips described above, you can solve the most common problems that you might encounter with your MacBook Pro or Air. If nothing works, the problem might be a bit more severe than anticipated, and you need to contact the Apple service center nearest to you.
