Just upgraded, and I’m seeing some of the Max start-up messages in the Console.app (ad_load, sched_start, etc.) but none of the printf()’s that I use in my code are appearing. Where have they gone? Oh Apple… sigh.
Just for fun I tried the old unix trick of "echo ‘hey’ > /dev/console" to see if I could possibly open and use it for console printing. That didn’t work either.
