Hi, I am new to the forum. I have installed teensyduino on win7 with no trouble. But I have an old Mac with OSX 10.6.8. Latest version of Arduino is not compatible. I did find version 1.6.0 which does install and start OK. Now I want to install Teensyduino, but I need to browse to the location where Arduino is installed. Where do I have to browse? No folder in Applications or inside the Arduino.app seems acceptible: the Next button is greyed out and remains that way.
