A:AnswerYes, although It will cover both the Magsafe port and the headphone jack. I would probably recommend using a cabled duel Thunderbolt adapter instead of one that mounts on the side of the laptop.
A:AnswerYes - I have an external monitor hooked up to it via my Mac without an issue....I close the Mac and have access readily to the monitor. I think that is what you are asking....
A:AnswerIt plugs into your Macbook with USB C, but has two USB 2 (or 3) ports, which I found to be unusable because I need to use two hands to pull them out, and even then it's VERY difficult. I'm returning it, I don't recommend it.
A:AnswerBought this for the wife’s MacBook Pro 13” M1 and fits perfectly with a protective case on the MacBook and has a spacer if you don’t have a protective case. I didn’t want to get her one with a dongle and this works great.
