I connected my 13 inch MacBook Pro to a Dell monitor via USB-C on the MBP to USB-C on the monitor (not using the power cord from the MBP, letting the monitor power the MBP) and when I shut down the MacBook Pro after a few seconds it turns itself on again. It doesn’t matter which USB-C port I use on the MBP, it won’t stop turning itself on when connected to the monitor. Does anybody have any idea how I can get it to stay off without having to unplug it from the monitor? I don’t turn off the external monitor, it goes to sleep. Should I have to turn off the monitor to stop the MPP from powering on?
