Most of the time my Apple stuff works gangbusters, but once in a while it does not. There is never any error message. There is never any way to troubleshoot. MOST annoying!
Yesterday I was driving up the the San Juans. I'd been listening to the Apple Keynote live on Apple.com on headphones from my phone, but when I got in my car I wanted to stream it through the car's Bluetooth stereo. The iPhone saw the Bluetooth, the iPhone streamed the conference, but A did not talk to B. I COULD NOT GET live streaming to play in the car. So I missed the last half of the conference. Grrrrrr.
Just now I wanted to print something up here. I have a printer on an air drop network so I can print from wireless devices like my iPhone and iPad. Both devices see the printer, the printer sees the network, I can queue print jobs to the printer.... But they never come out. Where do they go???? Grrrrrr.
