What's Wrong?

Desktop version: 1.3561.0 Claude Code CLI: 2.1.116 OS: macOS Apple Silicon Plan: Pro

Bug: Every Claude Code request in the Desktop Code tab immediately returns "Claude Code process exited with code 1" with no other output.

What works: Claude Code CLI in Terminal works perfectly. What fails: 100% of requests in Desktop Code tab, since v1.2581.0 (April 14).

Already tried: Fresh reinstall, bypass permissions enabled, OAuth auth, no API key conflicts, Full Disk Access granted, trustedDirectories configured. MCP logs confirm server connects and lists tools — crash is silent at all log levels.

Console.app: No errors logged at crash time. MCP logs: Server connects successfully, no tool calls reach MCP layer.

What Should Happen?

Claude Code requests in the Desktop Code tab should execute successfully and return results, the same way they do in Terminal.

extent analysis

TL;DR

The issue can be resolved by investigating the compatibility of the Claude Code Desktop version with the macOS Apple Silicon architecture, as the CLI version works perfectly, suggesting a potential issue with the desktop application.

Guidance

  • Verify that the issue is specific to the Desktop Code tab by testing other features of the Claude Code Desktop application to isolate the problem.
  • Check the system logs and Claude Code logs at different log levels to see if there are any error messages that could indicate the cause of the crash.
  • Consider testing an earlier version of the Claude Code Desktop application to confirm if the issue is indeed a regression and to identify the version where the issue started.
  • Investigate the "Bypass permissions mode" setting to see if it's related to the issue, as it's enabled in the steps to reproduce.

Example

No code snippet is provided as the issue seems to be related to the application's behavior rather than a specific code error.

Notes

The fact that the CLI version works perfectly suggests that the issue might be specific to the desktop application or its interaction with the macOS Apple Silicon architecture. The lack of error messages in the Console.app and MCP logs at the time of the crash makes it challenging to diagnose the issue directly.

Recommendation

Apply workaround: Since the CLI version is working, users can use the Claude Code CLI in Terminal as a temporary workaround until the desktop application issue is resolved. This allows users to continue using Claude Code for their needs while the desktop application issue is being addressed.
