Resetting the NVRAM (non-volatile random-access memory) or PRAM (Parameter RAM) on your Mac laptop can sometimes resolve startup issues. To perform this reset, start by shutting down your Mac completely. Once it is powered down, turn it back on and immediately press and hold the keys Command (⌘), Option, P, and R together. Keep these keys held down for about 20 seconds.
During this time, you may notice your Mac restart. Once you hear the startup sound for the second time or after seeing the Apple logo for the second time, you can release the keys. After this reset, your Mac’s settings related to audio, display resolution, and time zone should restore to default, which might rectify any configuration errors that were preventing the laptop from powering on.
What should I do if my Mac turns on but then doesn’t boot into macOS?
If your Mac turns on but fails to boot into macOS, there could be several underlying issues. Start by checking if there are any peripherals connected to your laptop. Sometimes, external devices can interfere with the boot process. Disconnect all peripherals, including USB drives, printers, and external monitors, then restart your Mac to see if it boots normally.
If that doesn’t resolve the issue, boot your Mac in Safe Mode. To do this, turn it on and immediately press and hold the Shift key until you see the Apple logo. Safe Mode runs checks and prevents certain software from loading, allowing you to troubleshoot. If your Mac starts successfully in Safe Mode, it may be worth looking into third-party applications or login items that might be causing the issue.
