Update crash

Hi giuliet87,

I'm sorry to hear that your MacBook isn't turning on after a software installation crashed. There are a few potential solutions you can try to get your MacBook up and running again.

First, try resetting the SMC (System Management Controller) on your MacBook. This can sometimes fix issues with power and other hardware-related problems. To reset the SMC, follow these steps:

1. Shut down your MacBook by pressing and holding the power button for several seconds.
2. Disconnect the power adapter and any other cables that are connected to your MacBook.
3. Wait 15 seconds.
4. Press and hold the power button for at least 10 seconds, then release it.
5. Connect the power adapter and any other cables that were disconnected.
6. Press the power button to turn on your MacBook.

If resetting the SMC doesn't work, you may need to try booting your MacBook in Safe Mode. Safe Mode is a diagnostic mode that can help you troubleshoot problems with your Mac. To boot your MacBook in Safe Mode, follow these steps:

1. Shut down your MacBook by pressing and holding the power button for several seconds.
2. Press the power button to turn on your MacBook.
3. Immediately press and hold the Shift key. You should see the login window.
4. Release the Shift key when you see the login window.
5. Log in to your MacBook using your user account and password.
6. Your MacBook will boot in Safe Mode, which may take a few minutes.

Once your MacBook is in Safe Mode, try installing the software again and see if the problem persists. If it doesn't, then you may have a problem with one of the other apps or services on your Mac. You can try disabling them one at a time to see if that fixes the problem.

If none of these steps help, it's possible that there is a hardware problem with your MacBook. In that case, it's best to take it to an Apple store or an authorized service provider for further assistance.
