ChronoSync is the professional choice for periodic backups, bootable drive clones and folder synchronizations. Target any device or folder visible in Finder such as a Volume, Thumb Drive, NAS, Disk Image, Server or another Mac. ChronoSync replaces your backup utility, drive clone utility, and folder sync utility with a single, powerful application.

What is new in this release:

  • Fixed a bug whereby the ChronoSync Scheduler would be spammed with quit notices from ChronoSync if the App was quit while a scheduled sync was running and the option was chosen to terminate all syncs.
  • Fixed a bug in the ChronoSync Scheduler whereby if it received too many termination notifications in a short period of time, it would cause the scheduler to hang.
  • Fixed a bug that could cause a deadlock if a Cloud Service Connection were told to disconnect while it was in the midst of collecting file system attributes.
  • Fixed a bug whereby enabling "Resolve Aliases" and encountering a relative symbolic link that referenced a folder outside of the sync tree would not properly follow that link.

What is new in version 4.7.3:


  • Implemented support for v4 authentication of AWS S3 commands.
  • Updated the predefined set of AWS S3 endpoints to include all the latest, v4-only regions.
  • Added the capability to specify a region identifier within the parenthesis to support future regions, or regions associated with S3 compatible services. If this syntax is used, the region identifier must be followed by /v4 or else v2 authentication will be used. An example of such an endpoint specification is: (region-identifier/v4)
  • Pre- and Post- sync shell scripts now receive an additional argument, the 'Run Mode' of the sync. 0=Standard, 1=Trial Sync and 2=Scheduled Sync.


  • Updated any 2016 references to 2017.

Bug Fixes:

  • Added logic to work around a memory leak in a system call on macOS 10.8. This affects uploading data to AWS S3. The solution applies only to macOS 10.8 and can be disabled, if needed.
  • Added logic to address a problem where, in some instances, the local agent takes upwards of 10 seconds to access the local keychain. Added a retry for up to 30 seconds to account for the slow response.
  • Fixed a bug in the Sync Document Log and Scheduler Log whereby log entries would appear to be truncated.
  • Fixed a bug in the Scheduled Items editor whereby editing an item for which its corresponding sync document could not be located would not allow you to save any changes.
  • Fixed a bug in the 'Choose Target' window whereby changing the selected volume in the left table by means of using the arrow keys on the keyboard would not trigger a volume change.
  • Fixed a display bug in the 'Choose Target' window to account for the display of a scroll bar on the volumes list.
  • Fixed a bug whereby the volumes list in the 'Choose Target' window would not scroll if there were more entries than were visible. This only affected macOS 10.8 and 10.9.
  • Edited the Retina version of the 'About' dialog graphic so that it does not include a border frame.

What is new in version 4.7.1:


  • Significantly improved performance when syncing with Google Cloud Connections. Depending upon sync contents, up to a 20% improvement can be realized.
  • Significantly Improved performance when syncing with Amazon S3 Cloud Connections. Depending upon sync contents, up to a 20% improvement can be realized.
  • Improved tracking of DMG volume location to better handle mounting and unmounting DMGs as well as the volumes they reside on.
  • Tweaked bandwidth limit calculations to more accurately match desired limits set in Connection Profiles.

Bug Fixes:

  • Fixed a bug that could cause a crash anytime after opening a Container Document even if the Container has since long been closed.
  • Fixed a bug whereby if a DMG on a file server were un-mounted by ChronoSync, the file server would not be un-mountable.
  • Fixed a bug whereby if targeting a DMG on a file server using "Mounted Volumes (Admin Access)", the server containing the DMG would not get automatically mounted.
  • Fixed a problem in Admin Access that could result in a crash under ideal timing circumstances.
  • Fixed a bug whereby the readiness manager would erroneously state "You cannot perform a bootable backup with the current boot volume as your destination." when switching between Bootable and Bootable Mirror operations with the same direction.
  • Fixed a bug in the Log Window whereby if you opened a log for a synchronizer document, then closed it while the sync was running (and generating log entries), then re-opened the Log Window, it would not 'snap' to the bottom of the log window.
  • Fixed a minor problem with Drag & Drop to the Scheduled Documents Manager Window.
  • Fixed a minor problem in the Registration Window and license key validation.
  • Fixed a problem whereby customers were being prompted for a Keychain Password.
  • Fixed a problem in Amazon S3 Cloud Connections whereby it was not properly setting the maximum number of concurrent operations.
  • Updated Online Help so terminology is more consistent with terms used in the App.

What is new in version 4.7b:

  • The synchronizer and container document Rename, Delete, and Duplicate now produce more meaningful error messages if those operations fail.
  • Fixed a bug whereby the "Duplicate" function was not properly duplicating container documents. Several items of metadata were not properly preserved.
  • Fixed a bug whereby the Document Organizer could fail to display on launch under certain scenarios.
  • Fixed a bug that would not re-display the Document Organizer if you opened a document that required a password to access and clicked "Cancel" from the prompt.
  • Fixed a bug that would not re-display the Document Organizer if you opened a document and received the "Document in Use" error message.
  • Fixed a bug that could cause a crash if a newly created synchronizer or container document were closed before it was fully displayed.
  • Implemented a custom configuration option (via plist settings) to return to creating "Untitled" synchronizer documents on application launch & activation.
  • Fixed an animation glitch that occurred when switching to bootable, local agent connection in a single step.
  • Fixed some bugs that could cause a hang or crash when selecting targets.
  • Fixed a cosmetic glitch whereby the deletion and readiness boxes were not animating properly on 10.9+.
  • Fixed a cosmetic glitch whereby the background of the detailed readiness message text view was being displayed in a subtle shade of grey.
  • Fixed a bug whereby bootable options for remote agents would be disabled if connection to the local agent could not be established for some reason.
  • Fixed a bug whereby collapsing a multi-level branch of files in the Analyze or Archive panel could result in the user interface for that document becoming unresponsive.
  • Fixed a bug whereby user and group names on a remote agent connection were not being properly displayed in the Analyze panel.
  • Fixed a bug whereby the "Last Synchronized" column in the Analyze panel was not updating in real time and could continue to show an erroneous value until a refresh was forced.
  • Fixed a bug whereby extended timeout values for local agent connects were not being established on initial connection attempts.
  • Implemented more efficient collection of file metadata such as as extended attributes and ACLs.
  • Fixed a bug whereby changes to a file's extended attributes were not always correctly detected when the EA sync trigger was enabled.
  • The file synchronization engine will now only force copying new files to a temporary file name on file server connections.
  • Added better fall-back logic for situations where some file systems produce errors when certain file access permissions are requested.
  • Fixed a bug in the "Verify Data" function that was not properly bypassing device caches.
  • The file copying logic now iterates file forks more efficiently.
  • Added the option to control file copying cache behavior via plist settings.
  • Eliminated some inefficiencies in the copy engine that were carry-overs from very early versions of the application.
  • Updated the volume blacklist for bootable targets and auto-exclusion.
  • Fixed some bugs in the diagnostic auditing mechanism.
  • Changed the terminology displayed in the user interface when selecting a custom location for the "Synchronizer Documents" folder.
  • Added workaround logic that should prevent various progress sheet windows from failing to show progress on certain systems.
  • Added logic to prevent accidental deletion of files when running the installer on 10.6 systems after a very specific (and obscure) sequence of events.
