Hello everyone, So I just bought a 13-inch MacBook Air. This is my first Mac (been a Windows user for 10+ years, not planning on going back). 1) Do you have any tips on setting it up, calibrating it (such as the screen, or general settings), or just things I should know/do in general? 2) When you buy a new Mac, what do you personally do to customize/optimize it to your needs? Thanks!
