Run Apple Diagnostics

Recognizing the problems is the first step to solving them, and that’s where Apple Diagnostics comes in handy.

How to run a diagnostic on Mac? If you have a Mac with an Apple Silicon chip, disconnect all the peripherals except the mouse, keyboard, and the other essentials > shut down your system > turn it on, and continue pressing the power button until you see the startup options screen > press Command + D.

If you have a Mac with an Intel chip, disconnect all the peripherals except the essential ones > click Restart from the Apple menu > press and hold the D key and select a language. Apple Diagnostics will start automatically, and if your system has any issues, you will see the options with the error code.

By running a diagnostic, you can resolve hardware issues on your Mac.


Fix unresponsive apps and accessories by giving your device a fresh start. Click the Apple menu > Restart or Shut Down.

Rebooting your system means clearing memory and cache files. So your device will start as new, and the problems you were facing will be resolved.

Whether your device is not connecting to the Wi-Fi network or the apps have frozen, you can restart your device.

If your system is not registering any clicks, press the power button for a few seconds to force restart your device.

You must shut down or restart your system at least once a week to ensure its smooth functioning.

Force Quit Apps

If an application is unresponsive or you can see the beach cursor on your screen, you can force quit the application.

Press the Command + Option + Escape keys to force quit a frozen application. Alternatively, you can click the Apple menu > select Force Quit.

Then, reopen the application to see if the problem is resolved.

macOS Update

It is essential to update the macOS to the latest version to fix bugs and leverage the updated security features.

Go to System Preferences > click Software Update and then follow the instructions on the screen.

Update Apps

Similar to macOS updates, apps also must be upgraded now and then. Head to the App Store to check if there are pending updates.

If you have obtained apps from outside the official App Store, go to the Check for Updates option in the application’s preferences window.

Keeping the apps up-to-date can prevent you from encountering problems like incompatibility, security issues, etc.

Restart Bluetooth and Wi-Fi

If you cannot use AirDrop or connect to the Internet, check your Wi-Fi connection and Bluetooth.

Navigate to the Control Center by clicking the Switch icon. Then, toggle off the Bluetooth or Wi-Fi icon and toggle it on after a few seconds.

If this doesn’t solve the problem, restart your system. You can also reboot the router.

However, note that if the problem is with your ISP, you have to wait for the issue to be resolved from their end.


Resetting the SMC and NVRAM/PRAM can solve many issues with your Mac. Here’s how to reset them.

  • SMC

The SMC controls several hardware functions like system performance, status lights, power supply, cooling fans, etc.

You can speed up your device or solve common problems by resetting the SMC. For example, users of M1 Macs can simply shut down their device and leave it for thirty seconds. The SMC will be reset.

Desktop Mac users can shut down their computers > disconnect the power cord > plug it in after fifteen seconds > wait five seconds to turn on their computer.

Users of Mac laptops with the T2 chip must shut down their system > hold the power button for ten seconds > release it > and press the power button to turn on their system after a few seconds.


If your screen has started up with the wrong screen resolution or you cannot figure out the correct boot disc, you can reset NVRAM/PRAM. The process is quick and harmless.

On M1 Macs, there are no special keyboard shortcuts. Instead, you must shut down your device and power it up after a few seconds.

On Intel Macs, you need to shut down your system > press the power button > press Command + Option + P + R keys as soon as your system powers up > keep pressing the keys for twenty seconds > let go of them > let your Mac start normally.

The Bottom Line

Making your Mac work again must be your top priority, especially if you are working from home. However, having to run to the service center every time something needs to be fixed is not ideal. Therefore, keep this troubleshooting guide handy.
