Adobe Acrobat Approval Client

is available for $40 to digitally sign documents that have been prepared for such signatures with the full version of Acrobat. It is covered in this PC World article. Like Acrobat Reader, Approval is a client that works with Mac OS 8.6, 9.0.4 and 9.1. [Update: Numerous readers pointed out that we misread the PC World article. Approval client is $40, not free as originally posted, but that's still much less than the full Adobe Acrobat. We apologize for the error.--Bill] [Dana Baggett]
