I used the icon font Apple released as part of the 30th anniversary of the Mac to create a couple 2560 × 1600 desktop backgrounds. I stuck to particularly notable Macs and the models I or my family have owned.
I’m wondering if Apple is going to release a 4K (or better) display alongside the new Mac Pro. Assuming Mac Pro and Final Cut Pro update availability is announced at the same event, it doesn’t seem like Apple to announce a machine that can power three such displays, unveil a version of Final Cut Pro with new 4K features and optimized for the new Mac Pro, and then tell everyone to go find a 4K display elsewhere and have fun calibrating it.
Always focus on good human interface, user interface. Computer apps are not to be judged by what they do or how well they do it. Rather, it is more important that they feel natural to normal humans and they are led to the right actions.
