What's Wrong?

Platform: macOS Apple Silicon (arm64) Claude desktop version: [check Claude menu → About] VM SDK version: 2.1.121 BuildID: 6efe4e93908606db428dd3cbdc8adf1ae5978587

file output: ELF 64-bit LSB executable, ARM aarch64 (Linux binary) Expected: Mach-O 64-bit executable arm64

All Cowork scheduled tasks fail. VM cannot start. Persists after full rm -rf of claude-code-vm directory and relaunch.

extent analysis

TL;DR

The issue is likely due to an incompatibility between the Linux binary and the macOS Apple Silicon platform, causing the VM to fail to start and scheduled tasks to not run.

Guidance

  • The error message indicates a problem with mounting a shared directory, suggesting a potential issue with the VM's file system or configuration.
  • The fact that the file output is an ELF 64-bit LSB executable, ARM aarch64 (Linux binary), while the expected output is a Mach-O 64-bit executable arm64, implies a mismatch between the binary format and the platform.
  • To mitigate this issue, try checking the VM's configuration and file system settings to ensure they are compatible with the macOS Apple Silicon platform.
  • Verify that the shared directory exists and can be accessed by the VM.

Example

No code snippet is provided as the issue seems to be related to binary compatibility and VM configuration.

Notes

The issue persists even after removing the claude-code-vm directory and relaunching, suggesting a deeper configuration or compatibility problem. The fact that this worked in a previous version implies a potential regression.

Recommendation

Apply workaround: Try to configure the VM to use a compatible binary format or adjust the file system settings to match the macOS Apple Silicon platform, as the issue seems to be related to binary compatibility.
