Signature not working on Mac in Adobe Acrobat Pro

[igolubic]

 

The standard insert signature button is not working on Mac OS. The device has the latest updates (Acrobat is also updated). When it is pressed, nothing happens. On Windows, with the same license account, everything works as expected. 

Expected behavior: to show a dropdown with signatures and scans of signatures as on Windows, or to show the possibility to add a new signature.

My problem is similar. Today 2025-09-10 Adobe fail to complete signing using latest version of Adobe Acrobat Pro and latest version of Mac OS. I have diligently taken all steps recommended by Adobe and the greater community, however the malfunction persists. Personally, I believe the malfunction is due to glitches  in Adobe software and not attributable to my OS, internet connection or any other third party software. Hence; I am hopeful and looking forward to a software upgrade that remove this highly disturbing issue. Thank you much. DDY.

Hi @Deng Da Yong, 

Thanks for reaching out. Sorry for the delayed response and troubled experience. 
If you are still experiencing this issue, have you tried testing the workflow with a different file? If the issue continues to persist, you may use Acrobat Web: https://adobe.ly/4o0DwNE;

I would appreciate it if you could record a video of your workflow and share it with us. That will help us understand your issue and replicate the scenario on our end.

Best regards,

I appreciate your input!  Sadly, this process still results in a black screen and a non-responsive Adobe application that must be forced to quit.  It happens when I try to add a signature. Thanks for sharing.
