After updating from MacOS 14.0 to 14.1 we got permission errors within an app we developed. We got an "operation not permitted" error if the app tries to access files on a samba network share which is mounted by another tool. Additionally, we got a "Permission denied" if the app tries to run programs outside the app, for example /usr/local/bin/ip. The app works fine on Catalina, Big Sur, Monterey, Ventura and Sonoma 14.0. The app and its components are codesigned and the app is notarized, no entitlements. In the Info.plist the NSNetworkVolumesUsageDescription key is set. Any ideas? Could it be that the app is sandboxed by default on MacOS 14.1? And we have to disable sandboxing via entitlement? Thanks for any input!
