Download Pairfold

Last updated: 13 November 2026

Prefer the App Store? Pairfold is also on the Mac App Store for USD 12.99 once, with everything included. A licence bought on this site and an App Store purchase are separate: each unlocks its own copy of the app.

The download is the full app. Without a licence you can make one folder pair, preview every change and sync it by hand, with every safety feature: temporary copies checked before they are put in place, the archive instead of deletes, and the stop when a disk is missing. A licence adds more pairs, schedules and runs when a disk or share is connected. You enter the key in the same app.

System requirements

A Mac with macOS 26 or later, Apple silicon or Intel.
Folders on the Mac, on external drives (APFS, Mac OS Extended, exFAT, FAT32) or on network shares mounted in Finder.
No internet connection is needed to sync. The app goes online only for your licence and for updates.

Installing

Open Pairfold.dmg and drag Pairfold to the Applications folder.
Open Pairfold from Applications and press New Pair.

Pairfold is signed with our Apple Developer ID and notarized by Apple, so macOS can check it. macOS may ask once whether you want to open an app downloaded from the internet. Updates come from inside the app (Pairfold, Check for Updates).

Try it on a copy first

Make a pair from a small test folder and an empty folder on your drive, press Check and Preview and read the list. Nothing changes until you press Sync. Everything stays on your Mac; see the privacy policy. Questions: support@kayabyte.dev.
