HI Guys I have recently asked to transfer my Windows creative suite to a Mac computer. I received the serial number but unlike my lightroom install disc, which is win and mac, my Creative Suite disc is windows only, how do I go about installing a Mac version of my creative suite onto the Mac computer?
