A:AnswerIt is compatible with any Apple laptop, desktop, Apple TV, and should work with any computer that has Bluetooth (though if connected to a PC, it will not have full functionality).
A:AnswerThe unit comes with USB-C to Lighting Cable, so you're good. And if you have Bluetooth with your IPAD Pro, you're good for using the Magic Mouse.
A:AnswerNo, especially if you bought the 16 inch version. The trackpad on that unit is the best in the business and a mouse can't keep up. The only reason I would use a mouse is if you just couldn't stand the trackpad, but I prefer the trackpad, even when working with Final Cut Pro.
