The only option you might have is to install a Windows emulation software on your Mac and install Acrobat thru it. Upvote. Iupgraded my Windows Adobe Pro to a MAC Adobe Pro. I had troubles with my Adobe CC so they removed all my Adobe products. Now I am trying to reinstall my Adobe X Pro and when I enter my Mac Upgrade serial numbers it says it needs another serial number which I do not have for the MAC because it was for windows Andcan we assume that you licensed Acrobat Pro 10 not as part of an Adobe Creative Suite?
