ChronoSync for Mac

HIGHLIGHTS:

• New time and event-based scheduling options.
• Remote triggering of Sync Tasks from ChronoAgent.
• Scheduled Task Manager and Organizer Window enhancements.
• Optional two-pass synchronizer and prioritized deletions.
• Significant iCloud and File Provider optimizations.
• Full compatibility with the latest generation macOS Tahoe.

ENHANCEMENTS AND CHANGES:

• Added the ability to run a two-pass synchronizer with optionally performing deletions first to the ‘Special File/Folder Handling’ section of the ‘Options Panel’.
• Added Remote/ChronoAgent Triggered scheduler type.
• Added a ‘Monthly’ (on weekday) scheduler ‘Simple Interval’ type.
• Added a ‘Yearly’ scheduler ‘Advanced Interval’ type.
• Enhanced ‘After ChronoSync Launches’ scheduler type.
• Added support for scheduling Validation runs.
• Added Custom Scheduler Notification Subjects settings.
• We now allow sorting by columns in Scheduled Tasks Manager window.
• Added scheduler suspension reminders.
• Added the ability to arrange Sync Tasks in the Organizer window by their next scheduled sync time.
• Added a more detailed display of scheduled run times/events in Scheduled Tasks Manager window.
• Significantly reworked how iCloud directory contents are asynchronously gathered, in an effort to eliminate a potential crash/hang scenario.
• Added logic to prevent descending into a folder if it is iCloud or File Provider managed and the source file system is frozen.
• Added better progress feedback for iCloud and File Provider file operations such as waiting for upload or waiting for eviction.
• Tweaked how effective download bandwidth limit is calculated in all Cloud Storage connection types.
• Added a bunch of new AWS S3 endpoints, and removed the Chinese ones.
• Added logic to coerce TIMEOUT errors to a more meaningful error code if they occurred as a result of dealing with iCloud-stored files.
• Significantly tweaked the eviction logic to improve performance (iCloud & File Provider connection types).
• Added significant logic to detect and properly deal with iCloud and File Provider managed files when NOT using a cloud connection type. This includes properly triggering cloud downloads, if possible, and reporting errors when the non-locally stored items cannot be safely dealt with.
• We now flag File Providers as having inefficient safe copy, thus triggering a Readiness Warning if safe-copy is enabled.
• Added the ability to locate paths displayed in log messages within the Analyze or Archive panels.
• Implemented better error message generation to try and display the actual file name instead of the temp filename.
• The bootable backup assistant now throws up a warning when running on Apple Silicon that states bootable backups may not work on this hardware and that the user should consider a Data Volume backup, instead.
• Added a new, ignorable readiness error when running on Apple Silicon that states bootable backups may not work on this hardware and that the user should consider a Data Volume backup, instead.
• The Admin Access Required Readiness test now applies to data Volume backups in addition to Bootable Backups.
• The Ignore Ownership Readiness test now applies to data Volume backups in addition to Bootable Backups.
• The Data Volume Readiness test now throws a warning if the destination volume is not APFS formatted.
• Added readiness warning that discourages ExFAT file systems.
• When choosing a target, we now dim the ‘Choose’ button after it is clicked to provide instant feedback when there is a high latency to display the Target Selector.
• Enhanced the ‘Description’ displayed on the Target Pane to better identify the location of Data volume targets.
• Enhanced archive handling to provide a better description of a custom archive location when the archive volume is not mounted.
• Added ability to manually mount archive volumes.
• Added logic that executes at termination to check if there are any minimized windows with sheet windows attached to them. If so, it de-minimizes them and aborts the termination so the user can dismiss the sheet(s).
• Implemented better feedback and perceived responsiveness to user pauses during file copies.
• Added logic to create a backup copy of Application Support/ChronoSync on first launch of ChronoSync 12 (only when a previous version of ChronoSync has been launched before).
• Changed default copy buffer sizes to 2 MB.
• Added corespeech/caches to the bootable/data volume blacklist.
• Added an automatic SmartScan reset if it has been too long since the last SmartScan sync was performed.
• We now track unmounted volumes in the volume caches to increase volume enumeration performance.
• We no longer allow a temp file created by ChronoSync for safe copy purposes to be marked for synchronization. Deletions are allowed and the user can manually delete the file as well. If they really want to copy such a file, they’ll have to rename it so it doesn’t conform to the .CSXXX nomenclature.
• Added thousands separators to the Progress Sheet.
• Updated online help.
• Now sorts the list of installed mail bridges.
• Added mail bridges for Airmail, Mailmate and Outlook.
• Removed mail bridges for old email clients.

BUG FIXES:

• Fixed a bug in all the modifier Setup Assistants whereby the activity status table could clip the last entry.
• Fixed a bug when displaying the ‘Next run’ summary for a scheduled item that was not factoring out the current minute.
• Fixed a bug that could fail to correctly set the path when dragging targets between Sync Task documents.
• Fixed a bug whereby quitting the application with an open editor field in the Settings window would fail to save that value to Settings.
• Eliminated the use of numerous, deprecated APIs.
• Fixed numerous display glitches when running on macOS Tahoe.
• Eliminated optional use of Core Animation (we always use it now).
• We now force a re-registration with the push notification server every 15 minutes and after a system wake.
• Fixed a bug whereby if the PrintInfo record was not encoded in a document, it would never get recreated.
• Fixed some accessibility bugs related to the rolling credits.
• Fixed a bug whereby file system live triggers were not compatible with the File Provider connection type.
• Fixed a bug whereby progress messages from a previous target task operation would be carried forward to new target task operations.
• Implemented a workaround for an OS bug whereby attempting to set certain super-user POSIX perms flags causes a crash on macOS Sequoia and newer.
• Fixed a bug whereby an exception raised when refreshing children of an archive node would not get caught.
• Changed some logic regarding the display of the Organizer Window on application launch. It would never display if it were launched in the background, which apparently happens on Tahoe after installation.
• Added some protection so that several methods do not execute when a document close is in progress in an effort to eliminate some crash scenarios.
• Fixed a bug whereby attempts to startup the file provider monitor would be indefinitely repeated if there were no file providers installed.
• Added logic that would prevent attempts to set certain POSIX flags that could cause the remote InterConneX to crash on iOS 26.
• Added more robust detection of whether or not we are currently reloading children before trying to update the display of entires, in an effort to eliminate a crash scenario.
• Added logic to safeguard against an exception being thrown when saving a sync tree to disk and the contents of the directory in that sync tree is modified while it was being saved.
