I'm trying to create a digital signature in a PDF document using Adobe Reader 9 for Mac OSX 10.5.8. When I click Document -> Sign, all the options are grayed out. How can I create a digital signature?
Thank you in advance.
I would assume you have to create an ID first:
- Choose Document > Security Settings.
- Select Digital IDs, and click Add ID.
- Select Create A Self-Signed Digital ID For Use With Acrobat.
- Follow the on-screen instructions to set up the self-signed digital ID.
