[Bug]: Browser doesn't start on mac, errors in initialization with logs attached

[openhands-agent]

Describe the bug and reproduction steps
This issue occurs when attempting to use OpenHands on a mac machine (Intel CPU). Despite having Docker configured correctly and switching between different LLMs (Claude, OpenAI, and Deepseek), the browser initialization fails with errors. The error appears immediately after connecting the codebase and attempting first interactions in the runtime setup. Full logs included below for detailed context.

Potential solutions

Look carefully at the order in which the processes or threads happen or could happen in browser_env.py. Is it possible that on some platforms they happen in a different, wrong order?
