Why do Adobe apps want to access my Contacts or Calendar?

In macOS Mojave 10.14 and later, Apple provides you a notification when third-party software requests access to your folders or content containing your private data.

Issue

Apple's privacy protections apply to the directories that contain your calendars, contacts, photos, mail, and messages. When trying to list or navigate through these directories, you may receive an alert that the Adobe app "would like access to your contacts", similar to the following:

Adobe apps do not require access to your calendar, contacts, or location, but you might unintentionally cause these apps to try to access these items. This can occur when you navigate within your user Library directory with either the Open or Save dialog.

These dialogs examine all files and directories within your user Library directory. This means that any app that needs access to any folder in /Users/<username>/Library can prompt such requests. 

Solution

If you encounter this prompt, simply select Don't Allow. It will have no impact on the operation of your Adobe apps. The prompts should only happen once per app (per security category). When you update your Adobe app to a new version, macOS remembers your earlier choices and won't prompt you again.

What happens if I allow an Adobe app to access my Calendar, Contacts, or Location?

If you allow Adobe apps access to these files in the directories, you allow the apps to browse the directories that contain these items. And you’ll be able to use the files in those directories.
