What are the troubleshooting steps for a Mac that won’t start?

When a Mac does not start properly, it can be a frustrating experience. There are several troubleshooting steps that can be taken to identify and potentially resolve the issue. First, it is advisable to check the power connection. Ensure that the power adapter is connected and functioning properly, especially for laptops. If using a desktop, ensure the power cable is firmly connected to both the wall socket and the Mac. Next, one can attempt to perform a basic reset of the system. This can be done by holding down the power button until the Mac turns off completely, then waiting a few moments before turning it back on. If the Mac still does not start, it is recommended to reset the System Management Controller, or SMC. This is done differently depending on the model, so it is useful to refer to the appropriate method for the specific Mac model. If the Mac still fails to boot, attempting to enter Safe Mode can be beneficial. This is achieved by holding the Shift key immediately after pressing the power button. Safe Mode runs checks and limits which programs and processes load, potentially revealing the cause of the boot failure.

If there are persistent problems, running Apple Diagnostics or connecting to an external display may also provide insights into hardware-related issues, which can be critical in diagnosing the problem.
