After updating the Claude desktop app on macOS (arm64/Apple Silicon), the Code, Cowork, and Dispatch tabs silently fail — messages send but nothing happens, no errors shown. Chat tab works fine.

Error Message

Running the binary produces: exec format error

Root Cause

The Claude Code VM binary at ~/Library/Application Support/Claude/claude-code-vm/2.1.92/claude is an ELF 64-bit Linux ARM binary instead of a Mach-O macOS arm64 binary:

$ file ~/Library/Application\ Support/Claude/claude-code-vm/2.1.92/claude
ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked,
interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0

Running the binary produces: exec format error

Fix Action

Fix / Workaround

After updating the Claude desktop app on macOS (arm64/Apple Silicon), the Code, Cowork, and Dispatch tabs silently fail — messages send but nothing happens, no errors shown. Chat tab works fine.

  1. Update Claude desktop app on macOS arm64 (or fresh install from claude.ai/download)
  2. App downloads VM bundle version 2.1.92
  3. The binary is Linux ELF, not macOS Mach-O
  4. Code/Cowork/Dispatch tabs silently fail

Code Example

$ file ~/Library/Application\ Support/Claude/claude-code-vm/2.1.92/claude
ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked,
interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0

Description

After updating the Claude desktop app on macOS (arm64/Apple Silicon), the Code, Cowork, and Dispatch tabs silently fail — messages send but nothing happens, no errors shown. Chat tab works fine.

Root Cause

The Claude Code VM binary at ~/Library/Application Support/Claude/claude-code-vm/2.1.92/claude is an ELF 64-bit Linux ARM binary instead of a Mach-O macOS arm64 binary:

$ file ~/Library/Application\ Support/Claude/claude-code-vm/2.1.92/claude
ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked,
interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0

Running the binary produces: exec format error

Reproduction

  1. Update Claude desktop app on macOS arm64 (or fresh install from claude.ai/download)
  2. App downloads VM bundle version 2.1.92
  3. The binary is Linux ELF, not macOS Mach-O
  4. Code/Cowork/Dispatch tabs silently fail

Attempted Fixes (none worked)

  • Deleting claude-code-vm/ directory and relaunching (re-downloads same bad binary)
  • Clearing app cache (~/Library/Caches/com.anthropic.claudefordesktop)
  • Resetting bridge-state.json
  • Full reinstall from claude.ai/download — same binary is bundled/fetched

Environment

  • macOS Darwin 25.3.0, arm64 (Apple Silicon)
  • Claude desktop app (latest as of 2025-04-11)
  • claude-code-vm SDK version: 2.1.92

extent analysis

TL;DR

The issue can be resolved by replacing the incorrect Linux ELF binary with a correct macOS Mach-O arm64 binary for the Claude Code VM.

Guidance

  • Verify the binary type using the file command to confirm it's an ELF 64-bit Linux ARM binary instead of a Mach-O macOS arm64 binary.
  • Check the download process of the VM bundle to ensure it's fetching the correct binary for the macOS arm64 architecture.
  • Consider manually replacing the incorrect binary with a correct one, if available, to test if it resolves the issue.
  • Reach out to the developers or support team to report the issue and request a corrected binary or an update to the Claude desktop app.

Example

No code snippet is provided as this issue is related to binary compatibility rather than code.

Notes

The issue seems to be specific to the macOS arm64 architecture and the Claude Code VM binary. The fact that the Chat tab works fine suggests that the issue is isolated to the Code, Cowork, and Dispatch tabs, which rely on the Claude Code VM.

Recommendation

Apply workaround: Manually replace the incorrect binary with a correct macOS Mach-O arm64 binary, if possible, or wait for an update to the Claude desktop app that includes the correct binary. This is recommended because the current binary is incompatible with the macOS arm64 architecture, causing the silent failures in the Code, Cowork, and Dispatch tabs.
