TL;DR

Try launching Claude in a non-maximized window to see if the issue persists, as the problem seems to be related to the maximized window state on MacOS.

Guidance

  • Verify that the issue is specific to MacOS by testing Claude on a different operating system if possible.
  • Check if the issue occurs when launching Claude in a non-maximized window to isolate the problem.
  • Test an earlier version of Claude, if available, to determine if this is a regression.
  • Consider providing more details about the system configuration and any recent updates to MacOS or Claude.

Example

No specific code snippet is applicable in this case, as the issue appears to be related to the application's behavior on MacOS.

Notes

The issue may be related to a compatibility problem between Claude and MacOS, particularly with the latest version of MacOS (15.7.4). Without more information about the system configuration or any recent updates, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Launch Claude in a non-maximized window until a fix is available, as this may allow the application to function normally.
