Download of FSPViewer 2.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program is included in Design & Photo Tools. We recommend checking the downloaded files with any free antivirus. The actual developer of this free software for Mac is Fulvio Senore.
From the developer:
FSPViewer is a free viewer for spherical (equirectangular) panoramic images. It is designed for viewing local (hard-disk, network or CD) high resolution panoramic images at full screen and with very high image quality. It uses advanced interpolation algorithms to show you smooth images without losing sharpness.
You may want to check out more software for Mac, such as Vectorworks 2010 Viewer, RealCADD or Polaris, which might be similar to FSPViewer.
