Top new features and changes in August 2019 release of Acrobat DC
Acrobat DC

Acrobat DC with Adobe Document Cloud services is the complete PDF solution for working anywhere with your most important documents. In the latest release, Acrobat DC is reimagined with simple and consistent user experience across desktop, web, and mobile-including touch-enabled devices.


Acrobat fully compatible with 64-bit macOS

While installing or launching previous versions of Acrobat on macOS 10.14 (Mojave), the following warning messages were displayed:

Warning - installer not optimized for your Mac
Warning - Adobe Application Manager not optimized for your Mac

Acrobat core code base was migrated to 64-bit with the Acrobat DC release in 2015. However, shared components were not migrated then, and that caused these warning messages.

In this release, all the shared components are now migrated to 64-bit for all the Acrobat tracks – DC, Classic 2017, and Classic 2015. As a result, no such warning dialogs are shown during application installation and launch.

Deprecated Mac APIs removed

In this release of Acrobat, many Mac OS X Deprecated APIs, particularly related to the file system access, are replaced with newer optimized APIs in core areas, such as Viewer, Distiller, Synchronizer, and Plug-ins. It's resulted in a huge improvement (70%) in the application launch time on all supported Mac OS with APFS file system. It's also improved the application’s responsiveness across various features and made it twice as fast as before.

These improvements are available in both DC and Classic 2017 tracks.

Preference to hide the quick action toolbar

When you select text or image in Acrobat, you see a quick action toolbar. Now you can hide the toolbar using a newly added preference. By default, the toolbar is enabled.

Steps to hide the toolbar:

  1. In Acrobat, go to Edit > Preferences (Windows), or Acrobat > Preferences (Mac).

  2. In the left pane, select General, and then clear the Show quick actions on text selection check box.

    Show or Hide the Quick Action toolbar
  3. Click OK.

For more information about preferences, see Viewing PDFs and related preferences.

Preference to reopen PDFs from the last Acrobat session

Acrobat can now automatically reopen PDFs from the last session on the launch. A new preference is added to enable or disable this capability. By default, the preference is disabled.

Steps to enable the preference:

  1. In Acrobat, go to Edit > Preferences (Windows), or Acrobat > Preferences (Mac).

  2. In the left pane, select General, and then select the Open PDFs from last session on Acrobat launch check box.

    Set Acrobat to reopen PDFs from the last session on the launch
  3. Click OK.

Improved messaging for Review and Share workflows

All strings, including labels, options, and messaging of the Share user interface are further simplified.

Note:

Adobe is testing this new PDF sharing experience in Acrobat DC. Therefore, the new experience may not be available to all Acrobat DC users.

For more information, see Share and track PDFs online (New experience | Old experience).

Support for CTK-based smart cards on macOS

You can now sign and certify PDFs in Acrobat DC and Acrobat Reader DC using CryptoTokenKit based smart cards on macOS.

Previous versions of Acrobat have support for digital signature using smartcards based on CDSA and used TokenD modules. Support for CryptoTokenKit based SmartCards is added in this release of Acrobat for both DC and Classic 2017 tracks. The option is available in Application > Preferences.

Enable CryptoTokenKit framework support
