A week has passed since the iOS update and now Sierra was released. I decided to fresh boot my Mac Pro and started from scratch. It was not as painful as I thought it was going to be. The only problem was the driver for my Razer keyboard was not yet updated, so I was back with the Apple keyboard. No big deal but I have to cut down on the gaming a bit.
All the other programs seemed OK. Even the Aperture - which is no longer natively supported by Apple seemed to working fine.
