SignalRoom Helper is an optional companion for deeper hardware monitoring in the sandboxed Mac App Store edition.
Download SignalRoom Helper
Download SignalRoom Helper 2.0 for Mac
Requires macOS 15 or later. Universal installer for Apple silicon and Intel Macs. The installer is signed by Rhys Ellwood and notarised by Apple.
The helper download is free. SignalRoom Pro is a separate App Store purchase, required to use the advanced monitoring features. Installing the helper does not purchase or unlock Pro.
Install and connect
- Download and open
SignalRoomHelper.pkg. - Choose Continue, then Install. Approve with your Mac password or Touch ID if requested.
- Return to SignalRoom. The helper connects automatically under the same logged-in macOS account.
- With SignalRoom Pro, open Settings → Advanced to check the connection. Choose Check again if needed.
You do not need to create an account, enter an API key or disable macOS security settings. The helper starts on demand when SignalRoom needs it.
What it adds
On supported Macs, the helper supplies GPU utilisation, CPU and GPU temperatures, fan speeds, disk activity and battery detail. Media integration depends on supported players and their permissions. Availability depends on the Mac and macOS version; not every reading is exposed on every model. Macs without fans or a battery do not show those measurements.
The helper runs as your logged-in user, not as root. Measurements stay on your Mac. Release versions of the app and helper verify each other's signing identity before exchanging data. The helper does not unlock Pro or replace the App Store purchase.
SignalRoom works without it
CPU totals and per-core activity, memory, network, storage capacity, basic battery and Calendar do not need a helper. Pro weather and user-approved local AI analysis also work without it. Unavailable hardware measurements are shown honestly, without requiring installation.
Connection help
If the connection is unavailable, confirm that installation completed, then quit and reopen SignalRoom. With Pro, open Settings → Advanced and choose Check again. The helper must run under the same macOS user as SignalRoom. If SignalRoom reports an incompatible helper, install the current download above.
Contact support if it still cannot connect; include the versions of SignalRoom, the helper and macOS. Do not send passwords, API keys or private usage logs.
Remove an installed helper
Quit SignalRoom. In Finder, choose Go → Go to Folder and move /Library/LaunchAgents/com.woodenamethyst.signalroom.helper.plist and /Library/Application Support/SignalRoom Helper to the Bin. Log out of macOS and back in to stop the current per-user helper process.
