A window group and a saved session can look similar while the windows are open, but they promise different things after a window closes or the Mac restarts. A group organizes live objects. A session system stores enough durable information to recreate some part of the setup.
Identify the layer being saved
“Save my workspace” may refer to several independent layers:
| Layer | Example of retained information |
|---|---|
| Membership | these current windows belong together |
| Resource | file path, webpage URL, project folder |
| Launch | which app should open the resource |
| Layout | size, position, monitor, or arrangement |
| Runtime state | terminal process, unsaved edit, in-app selection |
A product may support one or several rows. Never infer the last row from a screenshot of a restored layout.
Test restoration with a controlled window
Use a disposable file and webpage. Record their current state, close the windows, quit the applications, and restart the Mac only if the product claims restart persistence. Then note exactly what returns: the app, the resource, the window, its geometry, or its internal state.
Read tool-specific limits. Apple Terminal window groups can save arrangements of Terminal windows. Moom documents saved layouts and window matching. Workspace launchers register resources to open. These are related capabilities, not interchangeable guarantees.
Use the smallest dependable layer
If you only lose track of open windows during the day, a current-window group may be enough. If every morning requires reopening the same files and pages, use durable resource links or a launcher. If placement matters, add a layout tool. Preserve unsaved work in the source app rather than expecting any external organizer to capture it.
Wallo stores goals and tasks, plus mappings for current window identities. Closed or recreated windows can receive new system identities, so Wallo does not promise complete session restoration.
