Acrobat Pro9 on Mac suddenly won't print pdf unless I put it on Print Image. Downloaded updated drivers for Canon printer and restarted - same problem. Problem appeared after Adobe update, but not sure which one - within last 45 days.

Thank you for your reply. However, your statement seems to be inconsistent with Adobe's FAQ regarding OS X:

Is Adobe aware of any issues, bugs, or odd user experiences when using CC or Acrobat products with Mac OS X Yosemite?

Apple has improved security by introducing their new "V2 code signing" (it is a way to guarantee that the application came from the developer and has not been altered, infected with a virus, or damaged in any way). While Adobe is signing future updates with V2, some applications that are signed with the older V1 code signing may issue a warning: " can’t be opened because the identity of the developer cannot be confirmed." Learn more.

When using Mac OS X 10.10 with Safari 8, PDFs do not open using the Adobe Acrobat or Reader PDF browser plug-in. When opening a PDF in a browser, Safari's PDF Preview is the default PDF viewer. Explicitly set the Adobe plug-in as the default PDF viewer. Learn more.

In our testing, we have found no other significant issues with running Creative Cloud products with Mac OS X Yosemite.

When using Lightroom with Mac OS X 10.10, the Map module loads slowly or partially on some low-bandwidth Internet connections, or the following error appears: "Sorry, we have no imagery here." Learn more.

I see nothing in the above regarding "Acrobat Products" no longer operating with OS X except for the message that an application can't be opened due to lack of confirmation of identify of the developer. I do not have this problem.
