How can we help?

Getting started

Install ScreenHive on both Macs. The same app works as a Host (the Mac you share) and a Client (the Mac you use to control it).

On the Host Mac

• Open ScreenHive and choose Share Screen.
• Start the service. The first time, macOS will ask for Screen Recording and Accessibility permission.
• Keep the Mac awake and connected to the same network as the client.

On the Client Mac

• Open ScreenHive and choose Control Remote.
• Select the host from the Bonjour list, or enter its IP address.
• Enter the remote-control password set on the host.

Requirements

• macOS 13 Ventura or later on both Macs.
• Both Macs on the same local network (Wi‑Fi or Ethernet).
• Screen Recording and Accessibility permission on the host Mac.
• Local Network permission on both Macs.

Permissions

Open System Settings → Privacy & Security and check:

• Screen Recording — required for the host to share its screen.
• Accessibility — required to send mouse and keyboard input to the host.
• Local Network — required for Bonjour discovery and the connection itself.

After changing a permission, macOS may ask you to quit and reopen ScreenHive.

Troubleshooting

The host does not appear in the list

• Make sure sharing is started on the host and the menu-bar icon is active.
• Confirm both Macs are on the same network and not on a guest or client-isolated Wi‑Fi.
• Turn off VPNs or firewall rules that block local discovery, then try again.
• If discovery still fails, connect manually with the host’s IP address.

I can see the screen but cannot control it

• Grant Accessibility permission on the host Mac and reopen the app.
• Check that the host is not showing a permission or approval dialog that needs attention.

The screen is black or does not update

• Grant Screen Recording permission on the host Mac.
• Quit and reopen ScreenHive after changing the permission.
• If the host display is asleep, wake it and reconnect.

File transfer fails

• Check that the destination folder is writable.
• If the host is asking for approval, accept the transfer on the host Mac.
• Large transfers can be resumed by sending the same file again.

No audio

• Make sure system audio sharing is enabled in ScreenHive settings on the host.
• Check the volume and output device on both Macs.
• Some protected audio content cannot be captured by macOS.

Diagnostic logs

If you contact support, include your macOS version, ScreenHive version and a short description of what happened. Diagnostic logs may be available locally at ~/Library/Logs/ScreenHive or inside the app’s sandbox container. Logs are never uploaded automatically.
