Key Points

It seems likely that upgrading Docker Desktop to version 4.37.2 or later will fix the “com.docker.vmnetd” malware issue on macOS 15.3.2, as this addresses a code-signing certificate problem.
If the upgrade fails, manual steps like stopping processes and reinstalling can resolve it, but may require technical knowledge.
Research suggests this is a false positive by macOS security, not actual malware, so it’s safe to proceed with the fix.

Direct Answer

Overview

If you’re seeing a malware warning for “com.docker.vmnetd” on macOS 15.3.2, don’t worry—it’s likely a false positive due to a code-signing issue with Docker Desktop. Here’s how to fix it in simple steps.

Steps to Fix

Try Upgrading First: Open Docker Desktop, check for updates, and install version 4.37.2 or later. This should resolve the issue, as it fixes the certificate problem.

If That Doesn’t Work: Close the malware pop-up, then open Terminal and run these commands:

sudo launchctl bootout system/com.docker.vmnetd 2>/dev/null || true
sudo launchctl bootout system/com.docker.socket 2>/dev/null || true
sudo rm /Library/PrivilegedHelperTools/com.docker.vmnetd || true
sudo rm /Library/PrivilegedHelperTools/com.docker.socket || true
ps aux | grep -i docker | awk '{print $2}' | sudo xargs kill -9 2>/dev/null

Download and install Docker Desktop 4.37.2 from Docker’s release notes. Launch it and enter your password when prompted.

If Docker Is in Trash: Empty the Trash and repeat the steps above.

Unexpected Detail

You might be surprised to learn that this issue isn’t unique to macOS 15.3.2—it’s affected various macOS versions due to Docker’s certificate mishap, but the fix works across them.

Survey Note: Detailed Analysis of Docker Malware Issue on macOS 15.3.2

This section provides a comprehensive examination of the issue where “com.docker.vmnetd” is flagged as malware on macOS 15.3.2, offering a detailed guide for resolution and context. The analysis is informed by official Docker documentation, community forums, and GitHub issues, ensuring a thorough understanding for users and developers.

Background and Context

The error message, “‘com.docker.vmnetd’ was not opened because it contains malware. This action did not harm your Mac,” has been reported across various macOS versions, including Sequoia and likely macOS 15.3.2, given its recent release. This issue stems from a problem with Docker Desktop’s code-signing certificate, leading macOS security features like XProtect to misidentify the component as malicious. Notably, this is a false positive, not actual malware, as confirmed by Docker’s official communications and community discussions.

com.docker.vmnetd is a critical component of Docker Desktop on macOS, responsible for managing virtual networking via HyperKit or the Virtualization Framework. Its flagging disrupts Docker’s functionality, preventing startup and container operations, which is particularly disruptive for developers relying on Docker for containerized applications.

Analysis of the Issue

Research indicates that the root cause is a certificate signing snafu, where Docker inadvertently used an incorrect or expired certificate for some versions of Docker Desktop. This triggered macOS’s Gatekeeper and XProtect to quarantine the file, blocking its execution. The issue has been widely discussed on platforms like Docker Community Forums, GitHub, and Stack Overflow, with reports dating back to early 2025, aligning with the current timeline (March 20, 2025).

The problem is not specific to macOS 15.3.2 but affects a range of versions, suggesting a broad impact across recent macOS updates. However, given macOS 15.3.2’s recency, it’s reasonable to assume compatibility with the provided solutions, as no version-specific conflicts were noted in the research.

Detailed Solution Steps

To resolve the issue, users can follow a structured approach, starting with the simplest method and escalating as needed. Below is a table summarizing the solutions, their applicability, and steps:

Solution Type	Docker Desktop Versions	Steps/Actions	Additional Notes
Upgrade to Latest Version	All (recommended 4.37.2)	1. Open Docker Desktop, check for updates, install 4.37.2. 2. If pop-up persists, kill processes: `sudo launchctl bootout system/com.docker.vmnetd`, etc. 3. Download 4.37.2 from release notes, install, launch, enter password.	If in Trash, empty Trash and rerun.
Patch for Versions 4.32 - 4.36	4.32 to 4.36	Similar to upgrade: kill processes, close pop-up, download patched version (e.g., 4.36.1), install, launch.	Ensure patched version from release notes.
MDM Script for IT Administrators	4.32 or later	Run script to stop services, remove binaries, install re-signed versions from Docker app directories.	Suitable for enterprise environments, detailed in official docs.
Homebrew Casks Reinstall	All (using Homebrew)	Run: `brew update`, `brew reinstall --cask docker`.	Ensures latest version, useful for Homebrew users.

For most individual users on macOS 15.3.2, the upgrade to 4.37.2 is the recommended path. If the app fails to update, the manual process involves stopping Docker processes, removing the flagged binaries, and reinstalling. These steps require Terminal access and sudo privileges, so users should be comfortable with command-line operations.

Implementation Details

Upgrade Process: Users should first attempt an in-app update, which is the simplest method. If blocked by the malware pop-up, they can proceed to the manual steps, ensuring they download the installer from a trusted source, such as Docker’s release notes.
Manual Steps: The commands provided (e.g., sudo launchctl bootout) are designed to safely terminate Docker processes and remove the problematic files. Users must enter their administrator password when prompted, ensuring system security.
Post-Installation: After launching the new version, a privileged pop-up may appear, requiring password entry. This is normal and part of Docker’s setup for privileged operations.

Additional Considerations

Safety and Security: It’s crucial to note that this is a false positive, not actual malware. Docker has acknowledged the issue and provided solutions, as seen in their official blog post. Users should avoid third-party security software that might exacerbate the issue, focusing on Apple’s built-in protections.
Compatibility: Docker Desktop versions 4.28 and earlier are not impacted, but given the user’s issue, it’s likely they’re on a version between 4.32 and 4.37.1, necessitating the upgrade.
Community Feedback: Reports on forums and GitHub (e.g., GitHub issue) indicate that the upgrade solution has been effective for many users, with minimal reports of residual issues on macOS 15.3.2.

Unexpected Findings

An interesting detail is that this issue has affected a broad user base, not just macOS 15.3.2, highlighting Docker’s widespread use and the challenges of maintaining compatibility across OS updates. Additionally, the involvement of Homebrew as an alternative installation method (via brew reinstall --cask docker) offers a less common but viable option for tech-savvy users.

Conclusion

For users on macOS 15.3.2 encountering the “com.docker.vmnetd” malware warning, upgrading to Docker Desktop 4.37.2 is the most straightforward solution. If issues persist, manual steps involving Terminal commands and reinstallation should resolve it, ensuring continued use of Docker for development and container management. This issue, while disruptive, is well-documented and resolvable, reflecting the dynamic nature of software security and updates.
