What's Wrong?

Platform: Claude Desktop for Mac
App version: Claude 2.7032.0 (6c468a) 2026-09-22T05:53:19.000Z
macOS version: 26.6.2 Tahoe]
Mac model/chip: Mac Mini M4

What's wrong:
When I have an incognito chat open in the Claude desktop app and my Mac goes to sleep, the app reloads/refreshes the session when I wake the Mac. Because incognito chats aren't saved to history and can't be reopened, the entire conversation is permanently lost. This happens consistently.

What Should Happen?

The incognito chat should remain open after waking from sleep, as long as I haven't closed it. At minimum, the app should not reload the window while an incognito chat is open, or it should warn me before discarding it.

4. Wake the Mac and return to the Claude app.
5. The app has refreshed and the incognito chat is gone.

Workaround: preventing sleep with caffeinate -d avoids the issue.
