Acrobat DC, Acrobat 2020, Acrobat 2017, and Acrobat 2015 are compatible with the new macOS 10.15 Catalina. Major changes in user experience and known issues are described in this document.
- Acrobat 2015: If you download Classic 2015 Acrobat or Reader patches from the release notes or the FTP site, you see a notarization prompt and the installation is blocked. It's general behavior for all installer packages downloaded using a browser and not from the Mac App Store. To begin the installation, right-click the installer and choose Open.

A sample notarization prompt

- Recent: An OS permission prompt is shown if you open files from Recents, which were added in Recents before you upgraded to Catalina.

For more information, see Enable permission to access the folder | macOS 10.15 Catalina.
- Thumbnails of files in Recent and other areas: Thumbnails appear for those files for which Acrobat has read permission.
- Thumbnails of files in the landing pages of tools: The thumbnail is displayed only if Acrobat has read permission on the folder in which the file is located.
- Tools > Combine: For Microsoft Office files, when you add or convert an Office file for the first time, an OS permission prompt is shown. This experience is similar to macOS 10.14 Mojave.
- Select files from Recent files list and Combine: For each selected file, an OS permission prompt is displayed.

For more information, see Enable permission to access the folder | macOS 10.15 Catalina.
Network folder-based review initiation: A permission prompt is shown. Click OK to allow access to files on the network volume.
