Adobe for individuals [Can I use Cloud apps on Mac and Windows?]

Your Creative Cloud license works on either Win/Mac platform.  But if you attempt to install on a 3rd machine, your other 2 devices will be deactivated.  As @John T Smith  said, only 2 devices may be activated and only 1 machine may be used at one time.
