How to Troubleshoot Startup Problems With Your Mac

Macs are reliable and robust computers; however, they are not without issues. Many users of Macs have reported problems when starting their computer up, such as the machine needing to respond correctly or the system taking an excessively long time to boot up. 

It can be very frustrating and time-consuming; however, there are solutions and ways to troubleshoot and fix the problem. 

This article will discuss some of the most common ways to troubleshoot startup problems with Macs, focusing on those looking to purchase a refurbished device.

Common Causes of Mac Startup Problems

Regarding Mac startup problems, a few common causes are the root of the issue. These include corrupted system files, incompatible software, hardware issues, and viruses. 

Additionally, some users may experience problems if their startup disk is too entire or their system runs on an outdated macOS version.

Checking for System Corruption

One of the first things to try when troubleshooting a Mac startup problem is to check for system corruption. You will need to launch the Terminal application on your Mac and enter the command “sudo fsck –fy.” 

This command will check your disk for any corrupted system files and will attempt to repair any errors it finds. You may need to reinstall your operating system if the command cannot fix any errors.

Checking Your Hardware

If the issue persists, then you should move on to checking your hardware. Hardware issues are a common cause of Mac startup problems, so ensuring that all your hardware components are working correctly is essential. 

An excellent way to check this is by using the Apple Diagnostics tool, which can be accessed by restarting your Mac and holding down the D key. It will launch the diagnostic tool to check your system for hardware issues.

Check for Incompatible Software

Another common cause of Mac startup problems is incompatible software. If your Mac runs software incompatible with your operating system, it can cause various issues, including the Mac not starting up correctly. 

The best way to check for incompatible software is to open the Activity Monitor and look for any processes using excessive CPU or Memory. 

If you find any processes using excessive resources, you should remove them as they are likely causing the issue.

Check for Viruses

Viruses are another common cause of Mac startup problems and can be challenging to detect as they can hide in plain sight. 

You should use a reliable antivirus program such as CleanMyMac or Malwarebytes to check for viruses. These programs will scan your system for any malicious software and remove any threats they find.

Checking Your Startup Disk

Finally, you should check your startup disk to ensure it is not complete. If your startup disk is entire, then your Mac may not be able to start correctly. 

To check the available space on your startup disk, open the “About This Mac” window and click on the “Storage” tab. Here you can see the amount of available space on your startup disk.


In conclusion, Mac startup problems can be very frustrating, but they can be fixed by following the steps outlined in this article. 

Check for system corruption, hardware issues, incompatible software, and viruses, and make sure your startup disk is not full. 

If you want to purchase a refurbished Mac, run the Apple Diagnostics tool to ensure that the hardware is in working condition. With these tips in mind, you can troubleshoot and fix any Mac startup problems you may be experiencing.
