Mac Won't Turn on VS. Mac Won't Boot Up

Even though the result of a Mac that is not turning on or not starting up is the same - your Mac is not working, there is actually a huge difference.

A not turning on Mac means a Mac that is not responding at all after you press down the Power/Touch ID button or open up the lid on newer MacBook laptops. You don't hear a startup chime, a spinning fan, drive noise, and there are no visuals on your monitor. Your Mac shows a black screen and looks completely dead.

A Mac that refuses to start up looks a little bit better, because at least your Mac turns on and just the operating system isn't loading up. Your Mac boots to a strange screen, an unfamiliar symbol or never finishes the progress bar. Your Mac is still alive but is not functioning properly.

Check what screen your Mac boots to

A Mac machine that is not responsive requires completely different techniques to one that is not booting up. We will talk about a MacBook not turning on issue first.

How to fix MacBook not turning on?

After you power on your MacBook, your MacBook will go through a series of complicated events. The computer sends a signal to the computer power supply, which provides proper amount of voltage and electricity to computer's hardware components in a designed sequence. If all essential input and output hardware are functioning well and report no error, your MacBook will chime and the screen back-light will be activated.

The reasons why your Mac fails to power on vary. We will illustrate a series of checks and techniques to troubleshoot the unresponsive MacBook issue.

How to fix Mac not booting up?

If you can feel any signs of life such as a startup chime, air movement from the vent holes, and keyboard backlight, your Mac is turning on. After a short period of time, operating system will load up.

The modern operating system is loaded through a bootstrapping process, known as booting.

After the computer turns on, it first executes a small program (the first-stage boot loader) stored in ROM to initialize RAM to access the internal device containing operating system programs and data. Then the first-stage loader will load a more sophisticated second-stage boot loaderto do error checking, give the user a choice of operating systems to boot, load diagnostic software and other functionalities until the operating system is finally loaded up. Then, the boot loader will transfer the control to it and the operating system will initialize itself, configure the system hardware and load device drivers.

It is a complex process and could be terminated or jammed by any hardware or software errors. An iMac not booting up usually happens after OS update, system crash or incompatible/malicious software installation.

We will run through another sets of checks and fixes to get rid of the errors that prevents the operating system from loading or initializing.
