The Mac is designed to be stable for most users, but there are times when something goes wrong. In this article, you’ll find a set of troubleshooting steps that can fix issues ranging from a slow system or freezing, the infamous spinning beach ball from synchronizing an iOS device, apps not responding, and beyond.

This guide will help you troubleshoot your Mac step by step. The guide starts with the most basic troubleshooting tips and works its way up to more advanced techniques. I’ll focus on Mac problems that many MacBook Services like problems with Internet connectivity, display issues, some applications behaving oddly, like the Mac App Store not opening or not allowing you to download certain apps, problems with Wi-Fi or Bluetooth, problems with USB devices like printers or scanners not working correctly after having been previously working fine. It also covers problems that are unique to macOS like iMessages not sending properly, issues.

Apple’s support documents make it seem like these steps will solve all macOS problems. As a result, most people don’t think they need any additional help. If you find your macOS is acting up more than it should be, please read on, and hopefully, this will fix your problem.

How To Fix Common Mac Problems

  1. Reboot Mac
  2. Reset PRAM/NVRAM
  3. Boot into Safe Mode
  4. Reset SMC
  5. Repair disk permissions
  6. Verify disk (and repair if necessary)
  7. Reset Safari and clear caches
  8. Delete Caches folders
  9. Reinstall macOS

1. Reboot Mac

A computer reboot is a quick fix for many issues, so it’s often the first thing I recommend doing when an application has stopped responding. It’s also the easiest option–just hold down the power button. To make rebooting even easier, I’ve created a reboot menu app called Reboot Mac.

2. Reset PRAM and NVRAM

What are PRAM and NVRAM? From

Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM, on PowerPC-based Macs, this is stored in memory known as PRAM.

To reset PRAM and NVRAM perform the following steps:

  1. Turn off your computer.
  2. Turn on the computer.
  3. Press and hold the Command-Option-P-R keys before you hear the startup sound.
  4. Hold the keys down until the computer restarts, and you hear the startup sound for the second time.
  5. Release the keys.

3. Boot Into Safe Mode

Boot into Safe Mode by restarting your Mac and immediately pressing and holding the shift key until you see a progress bar at the bottom of the screen. That’s an indication that your Mac is booting into Safe Mode, which deletes a couple of additional caches. Once in Safe Mode, reboot normally, without holding the Shift key.

4. Reset the System Management Controller (SMC)

If your Mac computer is on and either: 

1) Has a spinning “question mark” icon on the screen.

 2) Has a grey screen with a horizontal flashing line. 

3) Does not start up at all or starts up and immediately shuts down and you tried using the steps above to start up into Safe Mode (located above), then follow these steps for resetting the SMC.

5. Repair Disk Permissions

Disk permissions are also known as file system permissions. They’re the first line of defense for your Mac against unwanted changes to your hard drive, and help protect files in the event of an attack by malware or viruses. Disk permissions are rebuilt automatically in OS X Yosemite or older versions when certain interventions are made, but for the most part, they don’t need to be self-repaired.

To do so, We have a nice little hack that can help you out. Did you know that OS X is able to fix the disk permissions on a drive even if it’s a hard drive inside your Mac? It’s true! While from time to time disputing disk permissions can lead to stability issues, most of the time having them repaired is a good thing. To do so, open Disk Utility.

6. Verify And Repair Disk

When your Mac won’t start up or an application freezes upon you, one potential solution can be to use Disk Utility (in later versions of macOS). To do so, restart your Mac while pressing Cmd+R on the keyboard. Then, in Disk Utility, click “First Aid” to start the disk verification and repair process. Once in the recovery console go into Disk Utility, select the primary hard drive of your computer and click on Repair Disk or First Aid, depending on your version of macOS/OS X.

7. Reset Safari And Clear Caches

Note: The option to reset Safari doesn’t exist anymore on newer versions of macOS.

 Reset Safari and clear all its caches?”. Sadly, sometimes this is necessary to get things back to normal. I’d rather not have it as a fix for problems, but unfortunately, that’s the case and it works. Reset Safari will reset Safari, removing all web data stored by the browser, including cookies, website data, autofill information, browsing history, and other private information. If you have a separate password manager (like 1Password.  Alternatively, you can remove website data from individual web pages via Safari > Preferences > Privacy > Manage Website Data.

8. Delete Cache Folders

Deleting cache files, also known as clearing the cache, has several advantages. Your Safari browser performs better, any application that stores information locally can save time and resources by rebuilding its own cache. Deleting cache files has no effect on the data you have stored in your ~/Documents folder. The next thing to do is move to your home directory. Then you go into the Library sub-folder. To clear your caches open Finder, press Command + Shift + g, and type in ~/Library/Caches.

9. Reinstall macOS

Restoring macOS is probably the most invasive, but also the only solution for fixing severely damaged software. When you reinstall, you restore all software, including system software and any bundled applications. Before you reinstall macOS, make sure you have multiple backups of your data—don’t rely on Time Machine alone. You should also make a note of important configuration settings so that you can restore them after the reinstall.

Reinstalling macOS can be quite an undertaking. You need to create a bootable install disk, erase your hard drive, install the software, and then reinstall your applications. What makes it even more challenging is that you probably do not remember your passwords for many of the services you use. I once lost my old Mac laptop and did not have backups or my passwords documented. That was a painful experience, to say the least. To make it easy, I created this document to help others reinstall macOS with minimum fuss (and maximum opportunity to screw up).


Are you having problems with your AppleMac? If so, you’re not alone. Many others before you have run into the same or similar issues. Sometimes it is just a matter of making sure that all of the system software is up to date. Other times, some more serious hardware damage may be at hand. The exact steps to resolve your problem will depend on why you’re having problems in the first place. However, if all of the steps above did not help to solve your issue, you can connect to CenturyItc support team or make an appointment at our Melbourne and Perth centers.
