There could be several reasons why my iMac won’t start up, and troubleshooting will depend on the specific symptoms you’re experiencing. Here are some general steps you can try:
1. Check Power Connection:
· Make sure the power cable is securely connected to both the iMac and a functional power outlet.
· If you’re using a power strip, ensure it is working properly.
2. Verify Display Connection:
· Check the display connection to ensure it’s properly connected.
· If you’re using an external display, try connecting directly to the iMac’s built-in display.
3. Restart:
· Press and hold the power button for a few seconds until the iMac shuts down.
· Wait a few seconds and then press the power button again to start it up.
4. Reset SMC (System Management Controller):
· If your iMac has a T2 chip, shut it down.
· Hold down the power button for 10 seconds, then release it.
· Wait a few seconds and press the power button again to start it up.
5. Reset NVRAM/PRAM:
· Shut down your iMac.
· Turn it back on and immediately press and hold the following keys: Command + Option + P + R.
· Keep holding the keys until you hear the startup sound for the second time, then release them.
6. Boot in Safe Mode:
