Thank you for this link. I'm In the same situation as the poster. I can't believe the lack of materials for MacOS. My guess is the money is in iOS right now and the tech is changing faster than training materials can keep up. Those iOS devices might be fun but you can't really DO anything on them. Well, you can draw I suppose and read. The big downside to that is nobody can become proficient fast enough so you have a few that know what they're doing and then you have the rest of us.
