Hello, I am in the final stages of buying a macbook pro 15. I would use this for school in addition with my braille display. My final questions are which processor would work best for my needs, school based elements, book readers, and so on? A 2.2GHz quad-core Intel Core i7 or 2.5GHz quad-core Intel Core i7? Based on that how much memory would I need? Finally would I need a blutooth trackpad to use zoom, voice over, and braille display together in no partiular order? Thank you, have a great day!
