Hello garys67795680
As per the description above, you want to know the path/location of your Digital Signature file on your Mac machine, Is that correct?
The default location of Digital Signature is saved in User/UserProfile/Library/ApplicationSupport/Adobe/Acrobat/11orDC/Security or ~/Library/ApplicationSupport/Adobe/Acrobat/11orDC/Security
You will find your Digital ID in this location. You can also check the location from Acrobat. Navigate to Acrobat's Preferences>Signatures>Under Identities and Trusted Certificates>Click on More>Highlight Digital ID files> You will be able to see your Digital ID information with the location.
Feel free to update this discussion for any further assistance.
Regards,
Anand Sri.
