I am using an iMac (OS X - 10.10.5 - Yosemite) - I have no problem with the IDE platform - however now trying the Web Editor - it does not detect the Arduino Uno I have plugged into the USB port. I get the message that you see in the subject line.
SO the IDE will work on the MAC and can see the Arduino without any problem - but using the Web Editor ( with Safari) - I cannot seem to get it to recognise/find the connected board.
Any tips on how I might get the Web Editor to find the board ?
Many Thanks
Jonathan
