Sync Checker is a diagnostic application which can check if two folders or disks are perfectly synchronized, i.e. if they have exactly the same contents. When creating backup copies of valuable files, or when making sure that two computers or mobile devices work on the same set of data, the status of being “in perfect sync” can be very important. In order to be safe and to prevent loss of data, you can let Sync Checker verify whether a pair of file collections are matching exactly or not.
- Added new feature to ignore time deviations of less than one second if desired when comparing the attributes of file system objects. This is necessary to get meaningful results when checking data between file systems that store time specifications with different precision.
- Added new feature to show time specifications of file system objects in millisecond resolution when necessary. This feature is available in macOS 10.13 High Sierra or later.
- The feature to ignore Time Machine attributes during a sync check has been extended to consider Access Control List permissions used by Time Machine as well. It is no longer necessary to disable all ACL checks when working with Time Machine files.
- The list of Extended Attributes to ignore during a Time Machine-related check has been updated for the latest macOS versions.
