Step 2: Once it's off, wait a few seconds and press the power button again to turn it back on.

Fix 3: Reset NVRAM and PRAM

Resetting the Non-Volatile Random-Access Memory (NVRAM) and Parameter Random-Access Memory (PRAM) can resolve various issues, including startup problems. Here’s how to fix the MacBook not turning on after update issue:

Step 1: Turn off your Mac, then turn it back on while holding the Shift key until you see the Apple logo on the screen.

Step 2: Once in Safe Mode, check if your Mac is functioning correctly. If it works, restart your Mac normally by selecting the "Restart" option.

Fix 5: Enter Recovery Mode and Run Disk Utility

Fix 7: Run Apple Diagnostics to Fix Your Mac

Apple Diagnostics is a built-in tool that can help identify hardware-related issues with your Mac. Here's how to run it:

In some cases, especially if the issue stems from a hardware failure, they may advise you to send your Mac in for professional repair or replacement.
