How to troubleshoot an iMac computer

Have you run into some trouble with your Apple iMac computer? All-in-one computers like the iMac can seem tricky to deal with, as everything is enclosed inside the device. Still, there are a few ways you can troubleshoot your Mac. Here are a few ways to test your iMac for problems, and solve a few software problems as well.

I hope this post will help you. If your Mac is still struggling, learn more about our Sydney computer repair services.

Restart the Mac

Some computer issues can be easily solved by a quick restart. It is the simplest form of a refreshment for any laptop or desktop computer. You might not expect how much you can achieve by restarting your Mac, but trust us, it can. It resets and removes the cached RAM data and can resolve a number of software bugs. Some might roll their eyes when they hear “have you tried turning it on and off again?”, but there is definitely truth in that advice.

To restart your iMac, just click the “Restart” button after you’ve closed everything. Or you can turn the Mac off as you normally do, then wait a few seconds before disconnecting the power adaptor plug. Wait another few seconds, then plug it back in and turn the iMac on again.

Run Apple Diagnostics

Apple Diagnostics

Apple Diagnostics is a great basic diagnostic tool that exists on every Mac computer, from MacBooks to iMac all-in-ones. This gives the user the ability to run checks on their hardware and see what’s wrong with the Mac. So if you’re trying to figure out why your iMac just crashed, or is running slower than usual, you might want to pull up Apple Diagnostics.

The procedure is simple: Restart your iMac, and then press the “D” key at start up. This brings you to a language selection screen, and Apple Diagnostics will start running after you choose a language. It will run tests on hardware like the hard drive, RAM, or fans. After the test, the interface will report hardware issues that it finds, along with support solutions to each problem.

Reinstall macOS

A software reset could also be helpful when your iMac isn’t running normally. Reinstalling macOS could help to get rid of various software bugs by giving the Mac a clean slate. Make sure you back up any important data before you do so, because this process wipes everything out. An easy drag and drop onto an external drive or a Time Machine backup should be enough.

You can reinstall macOS from the macOS recovery screen. To start your iMac in recovery mode, restart the Mac and hold Command + R until you see the Apple logo or a spinning ball. Then you’ll see a few options in front of you. Choose “Reinstall macOS”, and your Mac will download and install a clean version of macOS for you.

Getting support for your iMac

Because of how bulky the iMac is, there aren’t that many ways to test or troubleshoot it at home. Most parts are taped together and these all-in-one Macs require specific tools to open up. There isn’t much you can do if you don’t have the tools or technical know-how to do it yourself.

If you already know what’s wrong with your Mac after using Apple Diagnostics, great! Checking ahead with the geniuses at Apple should be the first thing to do. That way you know for sure that they can help you repair your iMac. You won’t have to waste a trip clumsily carrying around the computer.

There are situations where the Apple genius bar can’t help you. This might be because the iMac’s warranty has run out, or the problem is out of the genius’ reach. Then you might turn to a different computer technician to help you out.
