JumboJuice on macOS

Install an available Mac build through TestFlight and configure VPN access.

Installation and first connection

Install Apple’s TestFlight on your Mac.
Open the Apple invitation on Downloads. Check that TestFlight offers a compatible build for your Mac.
Install JumboJuice and sign in with your account email and password. Access appears automatically.
Choose a server, click Connect and allow the system VPN configuration request.

Build unavailable or VPN permission denied: TestFlight shows build compatibility and availability. If you declined the VPN dialog, reconnect and check VPN in macOS settings. Do not disable system protection to install the app.
Cannot sign in: Use the email of the account you paid with. If you forgot your password, reset it on the login page. Check Spam for the verification email.
Paid, but no access yet: Check payment history: payment may still be processing. After confirmation, refresh connections in the app. Contact support with the payment reference if access is missing. Do not pay again.
Cannot connect: Check that the internet works without VPN and another VPN is not running. Try another available server. If the problem only occurs on one network, mention that when contacting support.

Include your platform, app version, error time and message. Never send a password, verification code, full access key or payment details.
