I am currently running version 4.6.2.1 on a DELL Inspiron 9300 using Windows XP.  That laptop is going to stay at home when I work in the field.  I have acquired a MACPRO for field use.  Do I have to buy another copy of Photo Mechanic for this computer or can I download a MAC version using my existing subscription?  If I can download a MAC version is there anything about the process I need to know other than donwload to the MAC and use my code to activate it?
Thanks!
