If you start Bio7 a warning or error can occur because of the changes how Apple treats signatures! To allow Bio7 to start see this instructions for Yosemite, Sierra, Mojave and Big Sur:

First try to open the app with the context menu to allow the execution. If that won’t work try the following:

Yosemite: Open an app from an unidentified developer

Sierra: Open an app from an unidentified developer

Moave and Sierra: How to fix “Application” is damaged and can’t be opened error in macOS Mojave and High Sierra.

In addition for MacOSX you have to install R and Rserve (see below!).

Linux and MacOSX Rserve (compiled for cooperative mode) installation:

To install Rserve open the ‘Native R’ console in the ‘Console’ view and then execute the view menu action “Options -> Install Rserve (coop. mode) for R …” for different R versions (SSL 1.1 version for Linux Ubuntu > 19.10).
This will download and install Rserve in your default R library location, see video below (please make sure that your default Linux R library install location has writing permissions!):

How to install Rserve for Linux and MacOSX:

In cooperative mode only one connection at a time is allowed (which we want for this Desktop apl.) and all subsequent connections share the same namespace (default on Windows)!
