I paired it with my Apple MacBook Air but couldn’t get any files to transfer. So I emailed Derrick Story who’s a big fan of the Micro Four-Thirds cameras and who had already blogged that he’d got it working. He got back to me straight away and explained that you have to go to the Sharing Preference Pane and switch on Bluetooth Sharing. While you’re there you can also make “When receiving items:” read “Accept and Save”.
Now it all works fine and the PP-1 is a useful accessory! Thanks Derrick!
