I just published my first Apple TV App. It’s TV Map, an app to look at maps at the TV. As Apple since now didn’t port their Apple maps on Apple TV, I felt that something is missing. The app uses OpenStreetMap as data source and shows 4 different map types. You can navigate with buttons or use the siri remote to drag the map.
Shame on Canon not updating their Selphy printer driver for Mac Yosemite, But there is a solution. Christian Spuller created a Yosemite driver based on the mavericks driver:
Kein Druckertreiber für Canon Selphy unter Yosemite. Lösung.
Found out what the problem was as my Apple TV only showed a black screen when trying to mirror the screen: When transferring from my old iMac AirParrot was transferred too, this App causing the problem.
Solution: Remove driver as described here: http://help.airsquirrels.com/support/articles/1000106969-i-need-to-remove-airparrot-
