The MAS version of Accordance works fine with El Capitan public beta 2. I've removed all instances of it, to install the normal version. I've tried installing the latest one and one version earlier with Accordance chat help, both just instantly produce a dialogue box: The app "Accordance.app" cannot be opened.
Holding option upon launch doesn't change anything.
Has anyone figured out a way to run the normal Accordance app with EC PB 2?
