iOS 8.3, which was released to general public recently with numerous new features, performance improvements and bug fixes, however, iOS 8.3 apparently also brought security settings changes like preventing all the file transfer and management apps available out there for both Windows and Mac OS X from accessing the app directories of iPhone, iPad and iPod Touch, as noted by MacRumors. As a result apps like Macgo Free iPhone Cleaner and Macgo Free iPhone Explorer, which both need to access app directories to browse and manage files of users’ devices, have lost their access to the apps on iOS 8.3. And of course the rivals’ paid-for file managers and transfer utilities couldn’t escape from this disaster, such as iFunBox, iTools, iExplorer, iBackupBot and PhoneView.
