MacBook won't start, unable to turn on - solution

MacBook won't start. What to do if your MacBook won't turn on?

Your MacBook Pro won't power on? If your MacBook, MacBook Pro, or MacBook Air won't start, there are some steps you can try to resolve the issue.

Here is a guide to possible solutions/troubleshooting if your MacBook won't start:

1. Check power supply

Check charger: Make sure the power adapter and charging cable are in good condition. Test if the LED on the charger (for older models) lights up.
Test outlet: Connect the charger to a different outlet to ensure power is flowing.
Let the battery charge: Leave your MacBook connected to the charger for at least 15 minutes before trying to turn it on again.

2. Reset hardware

An SMC reset applies to Intel Macs; procedures differ for models with and without a T2 chip. Follow the relevant Apple instructions rather than a universal key combination. For this step on Apple silicon, restart or shut down and turn on with power connected.

3. Check the screen

Adjust brightness: Ensure the screen brightness is not set to the lowest level.
Connect an external monitor: Test if an external monitor displays an image to check if the issue is with the display.

4. Start MacBook in safe mode

Shut down the Mac. On Apple silicon, hold the power button until startup options appear, select the startup disk, hold Shift and click Continue in Safe Mode. On Intel, hold Shift immediately when turning on.

5. Use diagnostic tools

Shut down the Mac. On Apple silicon, hold the power button until startup options appear, release it, then hold Command (⌘) and D. On Intel, hold D immediately after turning on; if needed, use Option and D. Follow the instructions and note any reference codes.

Intel or Apple silicon: choose the right recovery

On Intel Macs, Option (⌥) + Command (⌘) + R starts Internet Recovery. On Apple silicon, hold the power button until startup options appear, then choose Options and Continue. iCloud syncing does not replace a complete Time Machine backup. Use the instructions for your specific Mac model.

6. Remove external devices

Disconnect all connected devices such as USB sticks, external hard drives, or monitors. These could be blocking your MacBook from booting up.

7. Repair firmware with a second Mac

Firmware repair on supported Apple silicon or T2 Macs requires a second suitable Mac, not just any Apple device. Try Revive first, which is designed to preserve existing data. Restore erases the affected Mac. Follow the model-specific instructions and back up first where possible.

8. Seek Professional Help

If nothing works, contact Apple Support or take your MacBook to an authorized service provider. Bring the charger and, if available, your purchase receipt.
