Safari 10 vs Adobe Reader DC
Since upgrading to Safari 10 I've been having problems with loading forms with Adobe reader
Is there a work around to this :
MacBook Pro, OS X Mountain Lion (10.8.3)
That message is Apple warning you, but in reality the latest Adobe Acrobat Reader DC Internet Plug-in works fine for me using Safari 10 on macOS Sierra.
I have loaded forms that I have created, tax forms, and other PDF without any issues. Make certain that you have the latest official update to Adobe Acrobat Reader DC (15.17.20053).
