Editors' Review

Users working between multiple workstations may need to access the same file from different computers and back up data between them. ChronoSync for Mac is a welcome program for those users and syncs data quickly and securely.

The program offers a free trial version available with a 500-file transfer limit while the full version requires $40 to unlock. The setup of ChronoSync for Mac went smoothly despite requiring acceptance of a lengthy user agreement. Upon first starting the program up, the user can choose to open a complete user manual, which is a welcome addition to this type of program, as novice users may not understand all of the features. Technical support for updates was also present. Upon starting, the user interface was easy to decipher, with left and right transfer folders similar to FTP programs for server upload. The user can select to back up and sync between folders in the same device, or on a different computer linked via a network. Many options are available to restrict or permit syncing of certain files or criteria. The buttons for operating the program's main features were easy to locate, even if the instructions were not used. Actual syncing completed quickly and without error, as would be expected.

For those users backing up files between networked computers, ChronoSync for Mac performs well and offers all expected features.

Editors' note: This is a review of the trial version of ChronoSync for Mac 4.3.7.

Full Specifications

What's new in version 4.9.1

UI Changes:

  • Task naming fields in all of the Assistants are now wider and no longer word wrap.


  • Added logic that tests if a disk image's parent volume resides on an SSD, in which case the disk image itself is denoted as an SSD. This affects the parallel file copying logic.
  • Added logic to cleanup an extended attribute that may have been applied to the user's home folder as part of a long-ago abandoned licensing scheme.
  • When ChronoAgent connections are establish, information about the nature of the connection is sent to the ChronoAgent much earlier in the connection process.
  • The Validator will no longer include 'Type/Creator Codes' in its Recommended Settings if either target is an InterConneX sharespace, but only if InterConneX is less than v1.3.0.
  • It is now less likely to timeout when un-mounting volumes or mounting disk images over a ChronoAgent or "Admin Access" connection.

Bug Fixes:

  • Fixed a bug that could raise an exception when opening or interacting with a Container Task Document on macOS 10.11.x.
  • Fixed a bug whereby Finder Tags attached to files were not being decoded into a format that the Finder Tags rule could understand. Thus the rule always failed to detect specific flags.
  • Fixed a bug that could cause folder enumeration errors on a mounted disk image over a remote ChronoAgent connection if the disk image was APFS formatted and stored on an HFS file system.
  • Fixed a bug whereby the Disk Image, Arbitrary Folder and Multiple Folders Assistants were not properly enabling the "Don't create empty folders" setting of the generate sync tasks(s) if document-type filtering was enabled.
  • Fixed a bug whereby all the Modifier Assistants would wipe out any custom tags assigned to sync task documents that were modified.
  • Fixed a bug whereby you could not target a sub-folder in an InterConneX sharespace.
  • Fixed a bug whereby restoring from the archive to a custom folder wasn't working if the archive's target connected to anything but "Mounted Volumes."
  • Fixed a bug whereby file copy operations and attribute-only copy operations were not responding to certain file system errors the same way.
  • Fixed a bug whereby having 'Strict Volume Identification' OFF was not working for locally attached devices.
  • Fixed a bug whereby losing connection to a target's remote file manager before a target path had been specified would make it impossible to reconnect to the remote file manager.
  • Fixed a bug whereby if creating a bootable backup to a remotely mounted, APFS formatted disk image over a ChronoAgent connection, if any of the device identifiers for the Preboot or Recovery volumes on the remote disk image happened to be the same as the Preboot/Recovery volumes on the source volume, ChronoSync would become confused and generate an error.
  • Fixed a bug whereby if creating a bootable backup to an APFS formatted disk image, it was possible for ChronoSync to report that it could not create the Preboot and/or Recovery volumes even though it had successfully done so.
  • Fixed a bug whereby files denoted as aliases by older, Carbon and pre-Carbon era software were susceptible to not being correctly identified as aliases.
  • Fixed a bug that could result in the improper identification of target volumes if there was more than one locally mounted volume that shared the same unique volume identifier.
  • Fixed a bug whereby certain kinds of pre- and post- sync AppleScript would not execute properly.
