Understanding and resolving MacBook problems

Do you have a MacBook that is throwing some serious tantrums? No need to sweat it! We are here to dive headfirst into unraveling the mysteries behind non-functioning Mac computers. Let’s not waste any more time in decoding and conquering pesky problems. 

Black Screen 

Once your Mac’s screen goes black, you’ll be staring into the abyss of darkness, not knowing what to do. It is normal to scratch your head thinking, “why did my MacBook screen go black?” and some of the plausible reasons are:

  • Battery issues
  • Overheating
  • Screen damage 
  • System glitches 
  • Hardware failures 

Now that you know the reasons behind the black screen of death, let’s look at the steps to diagnose and fix the issue. 

Start with some basic checks:

  • Verify your computer is connected to a power source and charging. Also, verify the brightness is not turned down too low. 
  • Close and open the lid to wake the display. 
  • Connect your computer to an external monitor via VGA or HDMI. If the image on the external monitor appears fine, the issue might be with the internal display. 

Troubleshoot the issue by following these steps:

  • Perform a forced restart by pressing the Control + Option + Command keys and the Power button. 
  • Reset NVRAM/PRAM, as this can solve display problems. You can read Apple’s support documentation for specific instructions on resetting this according to your MacBook model. 
  • Boot your computer in Safe mode. In this mode, only the essential drivers and software will load. This helps identify software conflicts that cause the screen to go black. 
  • Reinstall macOS. 

Slow Performance 

A slow-performing MacBook can limit your creativity and productivity. Some solutions to speed things up are:

  • Regularly check the storage space on your computer and remove all redundant applications, files, and media. 
  • Manage the startup items and prevent irrelevant items from starting up as soon as you switch on your computer. You can remove the items from the list by going to System Settings > Users & Groups > Login Items > uncheck the boxes next to the applications you don’t want. By trimming the startup list, you will be able to boost the startup time and improve the overall performance of the system. 
  • Disable the background processes by identifying the resource-intensive apps and programs in Activity Monitor. 
  • Ensure that you update the macOS software and the applications installed on your computer. 
  • You can reduce the visual effects and animation running in the background. Head to System Settings > Accessibility > Display and then reduce transparency and the other visual effects. 
  • You can even consider upgrading your RAM. 

Startup Errors

Is your computer not booting up properly? You can follow these steps to diagnose and troubleshoot the problem:

  • Verify all the cables are connected securely and that no hardware components are damaged. 
  • Reset the System Management Controller to fix startup issues. You have to follow the specific instructions for your Mac model. 
  • Boot into macOS Recovery Mode and run Disk Utility to find and repair disk errors. 
  • Finally, reinstall macOS. 


If your MacBook gets heated excessively, it can damage the internal components of your computer. The different ways to prevent overheating are:

  • Debris and dust can clog vents, which may impede airflow. This causes overheating. You must clean the vents regularly to prevent this. 
  • You must not use your computer in hot and humid environments. 
  • Check Activity Monitor and quit the resource-intensive applications running in the background. 
  • Place the Mac computer on a hard surface to ensure there’s enough ventilation. Do not place the computer on soft surfaces, such as pillows or blankets. 
  • Remember to service the fans because they require regular cleaning. This will improve its cooling efficiency.
  • Invest in a cooling pad so that your computer doesn’t get heated. 

Additional Troubleshooting Tips:

  • Calibrate the battery to improve the accuracy of the battery life. 
  • You can utilize advanced troubleshooting by using Terminal. This tool offers powerful commands for diagnosing and solving specific errors. 
  • Ensure that you install the available updates so that your computer can utilize the advanced bug fixes, performance enhancements, and security patches. 
  • Contact Apple Support if you have exhausted all other troubleshooting options. The tech support team will guide you and offer assistance so you can get back on track as quickly as possible. 
  • You can join online communities and forums so you can get a wealth of information and troubleshooting tips from other Mac users facing similar problems. 

It is essential to remember that you must always:

  • Handle your computer with care to prevent physical damage and damage caused by spills. 
  • Be cautious when you install applications or download files from untrustworthy sources. 
  • Ensure you perform regular maintenance tasks, such as updating software and cleaning your MacBook. This will guarantee optimal longevity and performance. 

So, there you have it! These are some common Mac problems and their resolutions. Hopefully, you won’t be panicked the next time your computer shows signs of a breakdown.
