I'm currently using LR3 on a Windows laptop but I want to upgrade to LR6 (the desktop version, not Creative Cloud) and am also just buying a Mac. What is the best way to go about this? Should I buy the upgrade to LR6 on my current laptop, and then use that serial number to download LR6 onto the Mac when I get it, or should I download the LR3 trial on the Mac, use the serial number I have to extend it to a full version and then upgrade to LR6?
Also, what is the easiest way to transfer all my presets and the edits I've done to the photos from Windows laptop to Mac, and how does this fit into the upgrade to LR6?
Thanks in advance!
