How to Fix Issues With a Mac Not Turning On

by Uneeb Khan

Got a MacBook Air or an iMac that won’t turn on, or maybe won’t boot past the Apple logo? Don’t worry. It’s frustrating, but usually fixable.

There are many places to get your macbook repair in canada. Apple Stores are the most obvious choice, but there are also many independent repair shops that can do the job just as well.

1. Check If the Mac Has Power

First, check that your Mac has a power source. Yes, it’s silly and obvious, but anyone who’s done tech support knows that you have to get the obvious fixes out of the way first. So if your MacBook won’t boot on battery power, plug it in. The battery may be fully depleted, or could be malfunctioning.

2. Run a Power Cycle

The next step is to run a power cycle. This completely cuts all traces of power from the Mac and enables you to restart it from scratch.

  • On a recent MacBook, including the Apple silicon models, disconnect the power cable and hold the power button down for 10 seconds.
  • For an older MacBook, disconnect the power cable and remove the battery for at least 10 seconds.
  • If you’re using a desktop Mac, disconnect the power cord for at least 10 seconds.

3. Boot Into Safe Mode

When your MacBook won’t boot, try to remember what you were doing the last time it was working. Were you installing apps, fiddling with fonts, or tweaking the system?

If your Mac shows signs of life when you power it on—if it displays but won’t go past the Apple logo or login screen, for example—then booting into Safe Mode may help you fix it.

  • On a Mac with Apple Silicon, turn it off, then press and hold the power button until you see the Startup Options screen. Now select your main drive, press the Shift key, and select Continue in Safe Mode.
  • On older Macs, press the power button and immediately press and hold the Shift key. Keep it held until you reach the login screen, then continue as normal.

Safe mode runs a bunch of diagnostic tests, then boots a stripped-down version of macOS. This doesn’t load your startup apps, custom fonts, extra hardware features, or anything else beyond the basics.

If your Mac boots successfully into Safe mode, it’s a sign that external factors are causing your problem. You can now start uninstalling any new apps, disabling startup items, removing hardware, or undoing any other recent changes that may be the culprit.

4. Use Recovery Mode Tools

To boot into Recovery:

  1. Press the power button.
  2. Press and hold the Command and R keys.
  3. Release the keys when you see the Apple logo.
  4. When it finishes booting, you’ll see a new macOS Utilities menu.

The one to try first is Disk Utility. This is a version of the same tool that’s available in macOS and enables you to scan and repair your hard drive or SSD. Select the drive and click First Aid to begin the repair process.

There are a few more tools available through the Utilities menu. These include the Terminal for more advanced users.

5. Reinstall macOS in Recovery Mode

You can do this through Recovery. Get started by pressing the power button and holding down the Command and R keys.

If you’ve got a recent Time Machine backup, you can restore that to see if it solves your problem. If not, choose Reinstall macOS from the menu.

When you choose to reinstall macOS, you’re given the option to format your disk as part of the process. Don’t select this if you simply want to repair your installation—there’s no problem with reinstalling macOS on top of itself.
