Set up Cairn Remote

1. Install and open Cairn for macOS.
2. Open Remote > Jump Host and complete the guided AWS setup.
3. Open Remote > Pair iPhone.
4. In Cairn Remote, tap the plus button and scan the QR code.

Connection troubleshooting

• Keep Cairn running on the paired Mac and make sure the Mac is awake.
• In Cairn for macOS, open Remote > Jump Host and confirm the tunnel is connected.
• Confirm the AWS account and CLI profile used during setup are still active.
• On iOS, open the host again after changing between Wi-Fi and cellular.
• Enable Settings > Show connection log to capture a local diagnostic log.

Revoke an iPhone

On the Mac, open Remote > Paired iPhones and remove the device. This removes its SSH authorization immediately. For complete credential cleanup, also delete the matching cairn-iphone-* IAM user from your AWS account.

Desktop access and iOS billing

Cairn for macOS is proprietary software that is free to download and use. Current desktop releases do not require an account, subscription, purchase, or license key.

Cairn Remote is a separate USD 19.99 App Store purchase in the United States. Apple handles its billing and refund requests. See the p10q refund information.
