Mac OS X iPad Charging Error with iPads on BC 1.2 Charging Hubs

With the addition of new BC 1.2 (USB-IF Battery Charging Standard) compatible charging hubs to our product line we wanted to shed some light on a bug we have discovered for Mac users. When using any of the following products an OS X pop-up error message may occur that claims the users iPad is not charging through the hub:

When checking charging status on the iPad itself, it shows that it is indeed charging and can also be confirmed in iTunes. To be completely sure, we test charging rates using a multimeter and confirmed the iPad was charging at the standard 1.5 amp BC 1.2 CDP (Charging Downstream Port) charge rate.

While this error message can be a nuisance, fortunately there is no cause for alarm as the iPad will be charging properly. For users who wish to disable this error message please see the steps below:

To turn off iPad notifications:
  1. Open the Terminal application (found in the Utilities folder inside the Applications folder), then type the following:sudo defaults write NoiPadNotifications -bool YES
  2. Then press enter (you may need to enter your password)
  3. Now type:sudo killall usbd
  4. Press enter
  5. Reboot computer
To turn them back on:
  1. Open the Terminal and type:sudo defaults delete NoiPadNotifications
  2. Press enter
  3. Type:sudo killall usbd 
  4. Press enter
  5. Reboot computer
