The 1.1.12 version of PDF Comparer for Mac was available as a free download on our website. This Mac application was originally created by Tarkware, LLC. The application is included in Productivity Tools.
From the developer:
PDF Comparer allows you to batch-compare PDF documents. The application uses Adobe Acrobat Pro to rasterize the PDF files and compare the images. Consequently, the program shows you the most different pages so you don't have to look at all the pages.
