I upgraded to the latest version of PM6 in March (26 March) and activated my Macbook Pro.
I've just opened PM6 and just trying to make sure the 'Browse with PM6' service launched the correct build (I still have the old Intel version in the applications folder, just in case) so clicked on the 'About Photomechanic' in the menu.. to see this..
I have no idea who this is, or why my Macbook has been assigned his license (which also expires months before my own)... but seems like theres an issue with activation here..
