how to properly disconnect macbook m1 at night with a connected monitor

You should be okay plugging and unplugging it every day. The ports are designed to have things plugged into them and unplugged from them all the time. That is the point of them, however, if you are very rough with the ports when you are plugging things and removing things from them, that could cause damage. If you aren't rough, then it should be okay for you to plug things in and out of your computer without causing damage. If you are really worried about it, I would suggest finding an extension cable or something along that line that you could plug into the computer and then plug and unplug the hub into that cable on a regular basis to protect the port on the computer from the constant use.

Hello Tgwhe,

Thanks for asking the Apple Support Communities about shutting down your Mac for the night.

Your Mac still uses power in sleep mode as described here: Save energy on your Mac - Apple Support

"When in sleep, your Mac is still turned on, but it consumes much less energy. And waking your Mac from sleep takes less time than starting it up."

You can look at those power saving options, or just turn shut your Mac completely down using the Apple > Shutdown. Log out, sleep, wake, restart, or shut down your Mac - Apple Support

Try shutting your Mac down but leave everything connected if you desire. Then see how it starts up and your power levels.

Thanks and have a wonderful day.

You can search Amazon for a USB-C Extension Cable and find what you need. I did a search and within the first couple of cables that popped up, found what you are looking for.
