MacOS – Mac asked me to force shutdown the laptop

I've never seen that.
A kind of shade slowly took over my screen and a message asked me to hold the power button until the macbook shuts down.

Here is the error report:

Should I worry? What does it mean? What should I do?

Best Answer

From your screenshots, it looks like you had a kernel panic. A kernel panic is an action which an OS takes due to a fatal error. More info on Wikipedia about kernel panics.

From Apple's support doc about kernel panics:

In most cases, kernel panics are not caused by an issue with your Mac. They are most likely caused by an issue external to your Mac. If the kernel panic doesn't happen again within a few weeks, you don't need to troubleshoot further.

All you need to do is hold down the power button on your Mac until it shuts down. Then, start it back up. If you are still experiencing kernel panics, Apple recommends that you boot up in safe mode to see if you still have kernel panics. Read the support doc for more information.

You shouldn't be too worried about a kernel panic. Usually they are caused by external things, and can be resolved by rebooting. If you continually get kernel panics, then you should start worrying. The support doc gives some advanced troubleshooting for kernel panics.
