Use compatible Thunderbolt ports and a Thunderbolt data cable. Older models may need adapters. Confirm the Thunderbolt Bridge network connection on both Macs. Ethernet is also supported.

The Host requires Apple Silicon and macOS 13 or later. The Viewer supports Intel or Apple Silicon with macOS 12 or later. Check both Macs’ supported macOS and network ports. There is no Catalina build.

Performance depends on resolution, quality mode, both Macs and available bandwidth. Automatic mode adjusts the streaming settings to suit the connection. Even Thunderbolt does not guarantee a constant 5K at 60fps.

Start with automatic. Choose quality priority for text and colour detail, responsiveness priority for interaction, or bandwidth saving to reduce network use. Responsiveness priority does not mean a fixed 60fps.

You can enable Wi-Fi on both apps when they are on the same local network. Thunderbolt or fast Ethernet is recommended for high-quality desktop sharing.

Enable remote control on both sides, grant Accessibility permission on the Host and click the received image. Some macOS-wide shortcuts may be handled by the Viewer first. Held input is released when focus moves away or the connection is lost.

Basic system audio sharing needs no separate driver. With the default capture method, muting the Host is supported on macOS 14.2 or later. If audio sharing or Host muting does not work as expected, you can use the optional EzDek Audio fallback. This method plays audio only on the Viewer.

Received items appear in the folder chosen in Settings when the transfer is complete. Folder structure is retained, and a timestamp is added to incoming names when needed to preserve existing files. If both apps support resuming transfers, an interrupted transfer can continue when you reconnect to the same Mac.

Screen sharing uses the local network; internet access is used to check the Host license. A check runs the first time Host is selected after launching the app and after a genuine internet outage ends. Stopping and restarting sharing without quitting the app reuses that check. If a communication failure persists in an app run that has already passed verification, sharing pauses after a recovery period of up to five minutes. A newly launched app cannot start sharing if verification fails. The Viewer needs no separate paid activation.

The trial runs for seven days from the first successfully shared frame and server confirmation. Reinstallation or clock changes do not renew it. Expiry applies during an active connection; purchase and manual checks remain available afterward.

One active Host registration is included; the Viewer is free. To move to another Host, complete online deactivation on the previous Mac. There is no transfer-count limit. Quitting the app or disconnecting does not deactivate a license.

For purchases, refunds or registration recovery, contact the seller through your Lemon Squeezy order receipt.

Go to Settings → General and choose Automatic or your preferred language. Automatic follows your macOS language preferences. A manually selected language is kept when you relaunch the app. Korean, English, Japanese, German, French, Simplified Chinese and Traditional Chinese are supported.

Choose Install and Relaunch to end screen sharing, save file transfer progress, and reopen EzDek after the update. If automatic installation is enabled, it waits for screen sharing and file transfers to finish.
