Sync Checker

Known Issues

When enabling exact byte comparison, the reverse status information is shown in the text report: If you perform a synchronization check between two folders with the option to compare each byte, and you let the application create a text report on the result afterwards, the introductory paragraph will include the notice “Files have not been compared byte by byte” which says the opposite.

Workaround: Download version 2.5 build 171204 to correct this typographical error.

Release Notes

When macOS asks for permission to let Sync Checker execute a privileged operation, the password panel has no keyboard focus: Depending on the authorization policies set forth in your operating system, macOS automatically opens a panel to enter name and password of an administrator each time Sync Checker likes to perform an operation which requires more than the usual rights of your user account. In this panel, the password entry field is not pre-activated, i.e. it does not receive input from the keyboard immediately. You have to click onto the panel or its fields first before you can type your input.

Workaround: This is a known defect of macOS. Applications which use multi-tier privilege separation (like Sync Checker) to fulfill Apple’s highest standards for system security cannot force macOS to display an authentication panel that becomes active immediately. In addition, the lock icon in the panel also won’t show an additional badge icon for Sync Checker. We have informed Apple about this issue and hope they will fix it in future versions of the operating system.

If the user’s preferences are set to show the user interface in a language different from English, this panel might contain a mix of English and non-English parts.
