TL;DR

The issue may be resolved by checking for updates or reinstalling the Claude desktop app, as the error message suggests, and verifying that the installation and launch process is correct.

Guidance

  • Verify that the macOS version, Tahoe 26.4, is compatible with the current version of the Claude desktop app.
  • Check the official Claude website or support channels for any known issues or updates related to the desktop app on macOS.
  • Try reinstalling the app from the official download link and ensure that the installation process is completed correctly.
  • If the issue persists, consider reaching out to Claude support for further assistance, as the error message suggests.

Notes

The issue seems to be related to a regression, as it worked in a previous version, but the last working version is not specified. The "command not found" response for the Claude Code Version suggests that there might be an issue with the installation or configuration of the app.

Recommendation

Apply workaround: Try reinstalling the app and verifying the installation process, as this is a non-invasive step that may resolve the issue, and then reach out to support if the problem persists.
