GoodSync
GoodSync is a file sync and backup app for Mac that helps you copy, mirror, and automate transfers between local, external, and cloud storage.
What is GoodSync?
GoodSync is a macOS file synchronization and backup app from Siber Systems. It is designed for people who want more control over copying, mirroring, and scheduling files than basic drag-and-drop transfers provide. Mac users commonly use it to keep folders in sync between computers, external drives, NAS devices, servers, and supported cloud storage services. The app supports automated jobs, one-way backup or two-way sync workflows, and detailed control over what gets copied or skipped. It can also run scheduled or unattended tasks, which is useful for ongoing backups and routine file maintenance. GoodSync fits personal and business workflows where users need repeatable file protection and synchronization across multiple locations.

Safety overview
Status: Mostly safe
GoodSync is legitimate backup and sync software. On Mac, it may request access to folders you want to back up or sync, and Full Disk Access can be a normal requirement when you include protected locations such as parts of your home folder or system-managed app data. Because the app can copy, overwrite, or delete files as part of a sync job, the main practical risk is using the wrong job settings or source and destination folders. Review each job carefully before running large or automatic syncs, especially if you enable two-way sync or deletion handling.
Recommendation: Keep GoodSync if you use it for backups, folder mirroring, or file synchronization across drives, servers, or cloud storage. If you no longer use it, you can remove it, but export or confirm any important job settings first and make sure no scheduled sync tasks are still needed.
