I just downloaded the PicoScope for Mac v220.127.116.11 from your web-site. When I was asked from you App I download and installed the Mono package (Mono Framework MDK-4.04.1) too.
However I still get the dialog “Mono installation not found. Go to Mono Project download page now?”.
To validate the Mono-Installation and build and run the basic apps from the Mono Basics page  successfully.
How should I start PicoScope?
Edit: The start via GUI does not work. A start at command “/Applications/PicoScope6.app/Contents/MacOS/picoscope” is possible.
Kind Regards from the Magdeburger Börde,
I have connected a PicoScope 3403D, OS X is 10.10.4
