Tools on This Mac checks what this Mac itself provides for the room's tools. Pressing Refresh looks again. The check reads what is installed. It never changes a setting, never contacts a service, and never sends a credential anywhere. On Windows the card says Tools on This PC.
Where to find it. Mac only, at the end of Settings → The room → Plugins, after the catalogue. It is a Mac card because it describes the Mac in front of you, which a web page cannot see.
The four checks
| Check | Ready means | When it is not ready |
|---|---|---|
| Command sandbox | Kernel isolation is available, and every command runs under it | Set Up opens Settings → This Mac → Workspace, where it is turned back on |
| Document files | Word, workbook, PDF and presentation support is installed with the app | Reinstall the app |
| Office rendering and recalculation | LibreOffice is installed, or its program is on PATH | Set Up ↗ opens LibreOffice's download page |
| LaTeX compilation | The bundled Tectonic engine, or an installed Tectonic, and an offline cache are here; it runs only under the sandbox | Set Up ↗ opens Tectonic's install page |
A check can also say Unavailable here, usually because this Mac has no kernel sandbox. Ready describes what is on this Mac, not a successful run.
Switches live elsewhere
Native App Control, Typed Data Feeds, Writable Background Delegates, Tool Action Programs, Nested Delegation and Devtools Tab Control are switches in Settings → This Mac → General, and each starts off. Connected Service Reads and Writes are under Service Permissions near the top of this page. MCP servers show their state in the Installed list.
When to use it. The lead says it cannot render a document, recalculate a workbook or compile LaTeX, or a command refuses to run for want of the sandbox.
