A Mac that won’t turn on is a whole different situation, as opposed to a Mac that won’t start up. If your problem is the latter, it means that you’ll be able to see something on your screen, or hear your device making a sound, be it a fan or other noise.

2. If that doesn’t work, then you have to boot your Mac in Safe Mode. This way, your device will run particular diagnostics, in order to isolate the problem.
