Can I still download Adobe X Pro to my Mac OS X Lion? Maybe download a free tiral, then enter the cereal number once the free trial is downloaded?
If you choose the download option when you made your purchase you will be able to download the software from your account. The following message thread details the process for locating and downloading your purchased software - http://forums.adobe.com/message/3980334#3980334.
There is no trial of Acrobat X Pro for Mac OS. Also Acrobat X Pro is compatible with Mac OS 10.7.
