"This Mac" lends a folder on your Mac to a cloud agent: it reads the files freely and asks before it changes any of them.
Use this when you want an agent to work with local files — code, documents, or data — without uploading them first. The agent works on the live folder, so it always sees your latest files.
- In the chat composer, click the folder chip and choose "This Mac".
- Pick the folder you want to lend.
- When the agent wants to change a file, the Mac app asks you first. Deny it, or allow the change.
- When you are done, choose Remove next to it in Settings › This Mac › Live folders.
Where: Mac app › composer folder chip (labelled "Add folder").
Good to know: to upload a copy instead, see Copy a folder on your Mac to the cloud.
