SintraWorks announces PDF Nomad 1.2

PDF Nomad is a PDF editor created especially for Mac OS X 10.7. It is not a direct update to PDFClerk Pro (and cannot be installed by this automatic updater). While there is considerable feature overlap, it does not offer some of the high-end features of PDFClerk Pro. At the same time it does offer some unique features of its own, and makes other features easier to use. Find out more about PDF Nomad on our website: PDF Nomad Info or Download PDF Nomad.

If you purchased PDFClerk Pro on or after Januari 1st 2011, you are entitled to a free cross-grade to PDF Nomad, which you can install next to PDFClerk Pro. If you purchased PDFClerk Pro before that date, you are entitled to a cross-grade discount. PDF Nomad automatically takes care of all types of cross grades for registered users.

  • Changed: Improved the automated license upgrade feature. It now needs even less user interaction.
