What it does
Three things Ferry does.
Made for video editors, photographers, musicians, and anyone moving large projects between a Mac and external drives.
Pause and continue
Progress is saved, so long transfers can continue after a pause, interruption, or app restart.
Source files stay put
Ferry copies files. It never deletes the originals or turns a transfer into an automatic move.
Saved transfers
Pause now. Continue later.
Ferry keeps durable checkpoints for interrupted and paused transfers. Reopen the app, review what happened, and continue when the drives are ready.
Common questions
Verified and resumable file copies.
Can Ferry resume an interrupted copy?
Yes. Ferry saves durable progress so a large Mac file transfer can continue after a pause, drive interruption, or app restart.
Does Ferry verify copied files?
Yes. It checks copied files and runs a final verification before marking the transfer complete.
Is Ferry a backup or sync app?
No. Ferry is a focused file-copy utility. It copies files to your chosen destination and leaves the originals untouched.

How to open Ferry on your Mac
This build is ad-hoc signed but not Apple-notarized. macOS may ask you to approve the installer once and Ferry once.
- 1
Open the installer
Open the DMG and double-click Install Ferry. Let macOS show its warning.
- 2
Open Privacy & Security
Go to System Settings → Privacy & Security, scroll to Security, and click Open Anyway.
- 3
Confirm
Authenticate and click Open. If Ferry itself is blocked later, repeat the same step for the app.
Keep Gatekeeper on. Use Apple’s one-app exception instead of disabling Mac security.

The app stays local.
The Ferry app has no analytics, ads, cloud sync, account, or automatic network updates. Transfer data and checkpoints stay in ~/Library/Application Support/Ferry.
What Ferry stores locally
Selected source and destination paths, backlog and checkpoints, file progress and checksum state, installer rollback copies, and a small health log.
Optional agent control uses a user-only local socket and records local agent activity when enabled. Bug reports are shown for review and editing; Ferry never sends one automatically.
This website uses privacy-friendly visit and download counters without public cookies or browser storage. It stores only one-way technical hashes—not names, email addresses, or raw IP addresses.

Help us join the Apple Developer Program.
We want future Ferry builds to be Developer ID signed and Apple-notarized, so they open without the extra approval step. Community support helps cover that membership and ongoing release costs.
Support is optional and is not a purchase or a promise of a release date.
