How to grant access to folders on macOS Catalina

Starting with macOS 10.14 Mojave, Apple has introduced a new security feature that ensures third-party applications work safely with your data. This means that now you have to manually grant access to your apps to let them work with the user`s files.

In recent macOS 10.15 Catalina, security rules have become more stringent. The system notifies you of any attempts to access your data. If an app wants to use data from a particular folder, you should grant access to it within this app, and again confirm this action in the system alert. Currently, macOS Catalina requires that you provide access to your Documents, Desktop, Downloads, and Bin folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external drives.

Duplicate File Finder is a software tool that finds and removes unneeded duplicate files, folders and similar photos from your Mac. So, these changes also affected the way Duplicate File Finder works. Using the Duplicate File Finder as an example, in this article we will show how to provide access to your data so that the application runs correctly on your computer.

Therefore, you need to give the application Full Disk Access so that the documents in the Bin are accessible.

Even after you have granted access to the Photos app, Duplicate File Finder and other third-party programs that work with Photos on your Mac, may still encounter some problems. You can see a pop-up window stating that the application does not have access to Photos in the following situations:

  • Your pictures are stored outside the Photos app. Thus, the system does not have Photos Library. However, in Duplicate File Finder, you can choose other folders in which your photos are stored.
  • Your Photos Library is empty. If there are no images in Photos Library, choose the folders in which you usually store your pictures for scanning via Duplicate File Finder.
  • photos library is empty

  • Use as System Photo Library is not selected in the Preferences of the Photos app. It is highly recommended to enable this option to allow Duplicate File Finder to work properly with the Photos app.

  • Copy items to the Photos Library is not selected in the Preferences of the Photos app. In this case, all the imported images to Photos from other sources will be shown in the Photos Library. However, they are only previews of the original pictures without full data. Therefore, Duplicate File Finder can not scan them to provide you with the correct results. So, enable this option so that the app can work with your images in Photos.
