Downloading Folseti 1.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. Folseti for Mac lies within System Tools, more precisely File Managers. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
Two simple shell scripts for starting the Seti and Folding command line clients with some instructions on configuring them.
You may want to check out more software for Mac, such as d-d Zone or SoundBite, which might be similar to Folseti.
