MacOS Agent Constantly Reconnecting Since First Installation

Support Help

Hello Cursor Team,

I am a Cursor Pro user on macOS.

Since the first day I installed Cursor, Agent mode frequently gets stuck with:

  • Reconnecting…
  • Taking longer than expected…
  • Requests hanging for 20-30 minutes

This happens even with a brand-new agent and a simple prompt such as:

“What is 2+2?”

The issue existed before today’s Anthropic outage and still occurs after the incident was marked as resolved.

Additional information:

  • MacBook (macOS)
  • Cursor Pro
  • Stable internet connection
  • Same network works perfectly on my Windows PC
  • Web version and other internet services are normal
  • Sometimes only one active agent is open and the issue still occurs

Has anyone experienced this on macOS?

Are there any logs or diagnostics I can provide?

Thank you.

Hey, thanks for the detailed report. The fact that Windows works on the same network but Mac doesn’t usually points to a network path issue on the Mac side proxy, VPN, or a security tool, not Cursor itself or the server. Your requests do reach the servers and the model responds, but the connection drops mid stream. That’s why you see Reconnecting and Taking longer than expected.

Let’s go step by step:

  1. Cursor Settings > Network > Run Diagnostics. Please run it and share the results.
  2. Disable HTTP/2: App Settings Cmd+Shift+, then search for HTTP/2 and turn on Disable HTTP/2. After that, fully quit and reopen Cursor, not just Reload Window.
  3. Since Windows works on the same network, check if you have any Mac specific tools that might be touching traffic like Little Snitch, Zscaler, a corporate VPN, MDM, or antivirus. Try disabling them temporarily and test again.
  4. Optional: pick a specific model instead of Auto and see if the behavior changes.

Let me know what the diagnostics show and whether Disable HTTP/2 helps, then we can dig in further.
