Yes. I saw somewhere -- I think on an Apple support page, maybe? -- that the powering-on-when-lid-is-opened is new to the MacBook in 2017, while it has been a feature of the 2016 MacBook Pros and of course the 2017 MacBook Pros. I'm still getting used to it -- in some ways it is convenient but in other ways it can be annoying if I just want to open the lid of the computer but not start up the machine right away. For example, when I first got the machine I didn't open it right away while I did some other things and then decided to go ahead and lift the lid, at least have a look but I wasn't quite ready to begin the process of setting her up yet. So I open the lid and -- surprise!! Machine turns on...... Ack! I found myself going ahead and setting the thing up right then and there after all. (In hindsight I realize now that I could have simply used the keyboard to Command-Quit and then shut down, but didn't think of that at the time. For the most part, though, it probably is a convenient feature, once the user becomes accustomed to it!
OK, here, found it:
Start up your MacBook Pro or MacBook by opening it or plugging it in
MacBook Pro models from 2016 and later and MacBook (Retina, 12-inch, 2017) start up when you open their lids or connect them to power. Learn more about these features.
If your MacBook Pro (2016 and later) or MacBook (Retina, 12-inch, 2017) is powered off, it turns on when you do these things:
- Open the lid of your Mac, even if it's not connected to power.
- Connect it to a power adapter while its lid is open.
- Connect it to a power adapter while its lid is closed and it's connected to an external display.
To start up your MacBook Pro or MacBook by plugging it in, make sure to use an AC adapter that provides sufficient power, like the one that came with the computer. For your computer to start up when you open the lid while it's not connected to power, the battery must have some charge.
