Hello,
I have read com.apple.security.app-sandbox entitlement is required for macOS applications distributed through appstore.
If so, how can it be possible for an application like Microsoft Word to read/write files in Documents folder ? It should be forbidden, due to sandbox ?
Thanks
Yes, sandbox is required for the App Store. You need to read some documentation: <https://developer.apple.com/documentation/security/app_sandbox/accessing_files_from_the_macos_app_sandbox>
