DeviceFinder 1.0.20 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X is a product of Paul Swindells. The application lies within System Tools, more precisely Device Assistants. 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:
Swintechnics Device Finder shows a real-time list of Swintechnics devices (e.g., mIoTa) available on your local area network, and gives detailed information about each device. The web site (if available) for each device can be accessed easily by pressing the 'OPEN' button for that device. The detailed technical information about a particular device can be shown by pressing the 'i' button.
You may want to check out more Mac applications, such as iStar Composer, SpaceReporter or Matchprint Virtual, which might be similar to DeviceFinder.
