MacBooks are fantastic machines, but they might lose their glory with time. If your system has started to show signs of trouble, you need to take steps so that your productivity is not hindered. By keeping in mind simple troubleshooting tips, you can easily overcome the hurdles and ensure your system is performing optimally. From startup showing a blank screen to Mac fans making excessive noise, this guide covers all the common problems you might encounter along with their instant resolutions.
Excessive Fan Noise
While Macs are reliable machines, their performance can get sluggish with time. If you are in the habit of multitasking, the chances are that you have multiple apps opened and working on several processes simultaneously. All these open apps, browsers or windows may overheat your Mac system and cause fan noise problem.
When Mac systems get overheated, the fans kick in to cool the system. That’s why you might be hearing excessive noise.
You can solve this problem by restarting your system, updating your system to the latest macOS version, ensuring proper ventilation and not using heavy applications.
The Startup is Showing a Blank Screen
If the MacBook startup has failed, it can show a few different colored screens. If you see a blue or black screen, your system has frozen while trying to load a problematic login function or application. You need to restart your system while pressing the power button for about six seconds. You can boot your system in Safe Mode if this does not work. You can also remove the troublesome login items or apps that might not be compatible.
If you are seeing a gray screen, it might be that essential software is failing and not functioning correctly. You can manually restart your system and open it in Safe Mode. If updates are pending, you need to update your system to see if it resolves the problem. You can stay in Safe Mode and use the Disk Utility tool to locate and fix disk problems that might prevent your system from functioning correctly.
The Display is Flickering
If your system’s screen is flickering, don’t start panicking right away. There are a few things that can solve the problem.
● Shut down your system and then Restart.
● Turn off Automatic Graphics Switching by clicking on the Apple icon and selecting System Preferences. Then tap Energy Saver and uncheck the box to avoid the screen flickering.
● You can reset SMC and PRAM/NVRAM if these resolutions don’t work.
● Check for macOS updates and click on Update to ensure your device is running on the current macOS version.
● You must check the power outlet and the physical connections to ensure they function correctly.
If these fixes fail to solve the issue, you need to head to the nearest Apple service center and get your system checked by a technician.
Bluetooth will not Turn on or off
Are you having trouble turning on or off Bluetooth? Head to System Preferences and click on Bluetooth to ensure all the settings are functioning. It might be that your Bluetooth isn’t turned on; all you need to do is turn it on.
If you still cannot connect to a Bluetooth device, ensure your Mac system is updated and restart your system and the Bluetooth device. This should solve the issue. If not, you can try moving to an open area and trying again. Bad interference might be the reason why Bluetooth devices are not functioning correctly.
If this fails, you can open the Terminal and force a reboot of your Bluetooth by typing the command sudo rm -R/Library/Preferences/com.apple.Bluetooth.plist and hit Enter. You might have to enter your password if prompted and then hit Enter again. Restart your system and turn on the Bluetooth to see if it works.
The System isn’t Shutting Down
MacBooks failing to shut down isn’t an uncommon problem because they might freeze during the process. If you have realized that your system has frozen and cannot complete the shutdown process, you need to check if open applications are causing the freeze. Open applications that refuse to close down might inhibit your system from shutting down. Therefore, you have to Force Quit the frozen applications and then try shutting them down. However, if this problem keeps happening, check if there are pending app updates. Update the apps and see if the problem is solved.
If the problem persists, reset the PRAM/NVRAM and SMC. You can also run Apple Diagnostics to identify and fix the problem. You can switch to Safe Mode if Apple Diagnostics fails to resolve the shutdown problems.
Conclusion
Macs are long-lasting, robust machines, but they can give you trouble. However, most issues can be fixed quickly. This guide will help you to resolve common problems without losing your sleep.
