In this article, we will show how to provide access to your data and continue using apps as usual, using Duplicate File Finder as an example. Understandably, the recent changes regarding file permissions have also affected the way Duplicate File Finder works. 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.ĭuplicate File Finder is a software tool that finds and removes unneeded duplicate files, folders and similar photos from your Mac. If an app wants to use data from a particular folder, you would need to grant access to it from within the app, and again confirm this action in the system alert. The system provides notifications of any attempts to access your data. With the recent macOS 10.15 Catalina version, security rules have become more stringent. Practically speaking, this means that you have to manually grant access to your apps in order to let them work with the user`s files. Since the release of macOS 10.14 Mojave, Apple has included a new security feature that ensures third-party applications protect your data.
