Requirements and install
CrocApp needs iOS 26, iPadOS 26 or macOS 26 (26.0 or any later version). The Mac app runs on Apple silicon only. There is no Intel build, no Windows, Linux or Android client, and no package-manager channel such as Homebrew.
The other device needs croc 11 or newer, whether it runs CrocApp or the croc command line. croc 10 cannot complete a transfer with CrocApp. See croc CLI interoperability.
Where to get it
The disk image for Mac is available now. The App Store and Mac App Store versions are coming, and crocapp.dev links them once they are live.
| Channel | For | Where |
|---|---|---|
| Disk image | Mac | CrocApp-<version>-arm64.dmg on GitHub Releases, version 1.0.0 or later |
| App Store | iPhone and iPad | Coming |
| Mac App Store | Mac | Coming |
Disk image
Open the disk image and drag CrocApp onto Applications. Use version 1.0.0 or later. The 0.9.x disk images are not notarized and use croc 10. From 1.0.0 on, Apple has notarized the app, so macOS shows only its standard first-launch confirmation.
To check a download before you run it, see Verify a release.
Use one channel per Mac. The App Store and disk image builds are both named CrocApp.app, so dragging the disk image copy into Applications replaces the App Store copy. Their data is kept apart, but one app takes the other's place.
Updates
- App Store builds update through the App Store.
- The disk image build updates itself. Choose Check for Updates… in the CrocApp menu. From the second launch on, it asks whether it may check automatically. It installs an update only when the update's signature matches the key built into the app. The check reads a feed on github.com and sends no system profile.
The App Store builds contain no updater, so they never contact github.com to look for updates. What changed in each release is on GitHub Releases.
