What's Wrong?

App: Claude for Mac v1.7196.0 (2dbd78)
OS: macOS 15 (Darwin 25.4.0)

Actual: Yellow warning banner appears: "Permission mode couldn't be changed. You can try again." Mode still switches to Auto and execution proceeds normally — appears to be a false warning.

Notes: Clicking plain "Accept" and then manually switching to Auto does not trigger the warning. Issue seems specific to the combined "Accept and auto mode" action — likely a race condition between plan acceptance and permission mode switch.

What Should Happen?

Frequency: Reproducible consistently — happens every time I accept a plan with "Accept and auto mode".

Error Messages/Logs

Steps to Reproduce

1. Enter Plan mode
2. Claude proposes a plan
3. Click "Accept and auto mode" (⌘↵)
