Gateway: Relay binary not copied to ~/.unity/relay/ on Editor startup (macOS)

Description
According to the documentation, the Relay binary should automatically be copied to ~/.unity/relay/ when the Unity Editor starts. However, this does not occur when using Unity Editor 6000.3.10f1 with Assistant 2.0.0-pre.1 installed on macOS.

Because the binary is not copied, MCP configuration fails when attempting to use it with Claude Desktop.

Steps to Reproduce

1. Install Unity Editor 6000.3.10f1.

1. Install Assistant 2.0.0-pre.1.

1. Start the Unity Editor.

1. Check the directory ~/.unity/relay/.

Expected Behavior
The Relay binary is automatically copied to ~/.unity/relay/ during Editor startup.

Actual Behavior
The Relay binary is not copied, and the directory remains empty or missing.

Additional Notes

• No relevant errors appear in the Unity Console.

• The “Locate Server” button in Project Settings did not work for locating the binary.

• Manually copying the binary via Finder did not resolve the issue.

• The issue was eventually resolved by copying the binary via Terminal from the package folder.

Environment

• OS: macOS

• Unity Editor: 6000.3.10f1

• Package: Assistant 2.0.0-pre.1
