I known there are a number of Fortran users so I thought I’d highlight this message

The Absoft Pro Fortran 2012 for Mac OS currently shipping is compatible with Mountain Lion.  Absoft Pro Fortran 2012 Mac OS customers who purchased earlier than June 2012 who want to run on Mountain Lion will need to download the Service Pack v11.5.2 which can be done at no charge from the Absoft site: http://www.absoft.com/download/downloads.html

Pro Fortran versions prior to 2012 are not compatible with Mountain Lion and will require an upgrade.
