I just purchased Adobe Acrobat Pro for Mac yesterday, but cannot find the Fill & Sign button/pane where I should be able to insert ink signatures (not digital ones), place initials on the document and such. Could it be that my Pro version does not have this feature?
Look under Tools.
On the PC version when you choose create form there is a check box on the screen asking if the form will have signatures. If you check the box the form you create can be used with Fill&Sign with the ink signatures - but you cant use the older version of digital signatures and distribute function. If left unchecked you get the option to distribute the form and use the digital signatures.
