Hello,
I accepted to install an update on my MacBook. Since then, my computer has taken a long time to restart, and then it displayed "Select the system to use to start your computer" and "after restarting the computer, you can connect it to another computer and use it as a hard drive" and I had to click either "cancel" or "restart".
So having no other option, I clicked on restart. And since then, the screen is black with a white lightning bolt moving across the screen.
Basically, my computer is in target disk mode and I can't get out of this mode...

Hello,
The white lightning bolt moving on the screen indicates that your MacBook is in target disk mode.
Target disk mode is typically activated by holding down the T key (like Target) during the Mac's startup.
To exit this target disk mode, simply turn off the Mac and restart it without pressing any keys.
My questions are:
• what update did you perform to get there?
• did the Mac indicate during this update that there wasn't enough space on the internal disk?
If yes: then you are supposed to connect your Mac to another Mac in order to transfer your data to the other Mac to make space (Transfer files between two Mac computers using target disk mode. Note: when transferring, it means copying the files to the other Mac and then deleting them from your MacBook. After you have freed up enough space on your disk, you will need to restart the installation.
If no: then I don't understand why the MacBook would have entered this state by itself. For your information, here are the keyboard combinations that a Mac recognizes during startup.
If you have a backup of your data, you could reinstall MacOS using the keyboard combination suggested depending on whether your Mac has an Apple chip or Intel.
