Hi there, I am maintaining an application in c++ using Xcode . This app has the ability to read and write files and pictures. It worked for a long time pretty well but after a period of a few month I tried to upgrade it and some issues come up. Although the app is running , I can not read and write files as I did in the past.  As an example when I am trying to save a picture I saw this message and the picture is not saved : GetDYLDEntryPointWithImage(/System/Library/Frameworks/AppKit.framework/Versions/Current/AppKit,_NSCreateAppKitServicesMenu) failed. Program ended with exit code: 0 Are there any permissions that required to update in the info.plist or anything like that ? The  applications is still working on other operating systems with out any issues.   Kind Regards Georgios
