SyncMirror
Utilities
Only for Mac
$3.99
Mac
Sync any number of folders both ways. Newest file wins. Backup snapshots with stale detection. One window, one button, no cloud — files stay on your drives.
SyncMirror keeps your folders in sync — across drives, volumes, or any local directories. Add as many folders as you need, press Sync, and the app mirrors them using a newest-file-wins strategy.
• Two-way sync — changes propagate in both directions. The most recently modified file is always the source of truth.
• Unlimited folders — sync between your main drive, external disks, cloud-mounted directories, or any combination.
• Folder groups — organize sync targets into independent groups, each with its own sync state and backup schedule.
• Backup snapshots — create timestamped backups before syncing. SyncMirror warns you when the last backup is older than 7 days.
• Safe by default — if a sync would delete more than 50% of files, the operation stops and asks you to check your folders.
• Sync preview — review additions, updates, and deletions in a diff sheet before each sync, then confirm.
• No cloud, no account — everything stays on your machine. No data leaves your Mac.
SyncMirror is built for macOS 14 and later. No subscriptions, no analytics, no telemetry.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Added folder groups: organize sync targets into independent groups, each with its own sync state and backup schedule.
- Added a sync preview sheet before each run: review additions, updates, and deletions, then confirm.
- Added per-group backup with the ⌘B shortcut and a warning when the last snapshot is older than 7 days.
- Added primary and copy folder roles: mark one folder as the source of truth, the rest mirror from it.
- Reworked the interface to native macOS conventions: NavigationSplitView sidebar, toolbar, and standard keyboard shortcuts.
- Improved the sidebar: collapsible group headers with sync status, and the option to hide groups or individual folders.
- Changed delete behavior: a missing file in one folder no longer triggers a deletion in others; files present in any folder are restored to all locations.
