So does anyone have an answer to this? How about a company rep responding

I've been using ES for years, but now need a bit of help. In using a Mac with Yosemite, which version of the free software should I download and which pedal do I buy. I have a USB pedal that I have been using with an older version of ES on A Mac, but It doesn;t work with the new ES version,.I can;t seem to get a straight answer from either the software or the pedal people. Any help most appreciated.
