Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

For the past 48 hours, Cursor has been almost unusable.

  • extensions won’t load
  • terminal won’t start
  • chat freezes after 3 minutes (and then stops working)
  • can’t close the app properly (stuck on loading screen)
    Lost 4 days of chat history after >20 min stuck. Tried logging out/in and restarting—did not help.

Steps to Reproduce

  1. Open Cursor (MacBook Pro M2 Max, macOS Tahoe 26.0.1)
  2. Attempt to load extensions
  3. Try to start terminal
  4. Use chat (works briefly if i log out and in, then breaks)

Expected Behavior

Everything should work normally: extensions load, terminal starts, chat stays open and saved chats remain accessible.

My SSH Issue

There are some similar symptoms that I have expericenced with the new version. Not sure if they’re related but are you connected to your codebase via ssh?

After the latest update, Cursor has stopped working properly. The cursor freezes indefinitely — I can still click around tabs and files, but files never open and remain stuck in a loading state.

I’ve already tried killing all background processes (over 20 of them) and restarted my PC, but the issue persists. It looks like I might need to reinstall the app unless there’s another fix available.

Hey, thanks for the report. Several users on macOS have seen similar freezes/instability in recent 2.0 builds. Let’s try these steps:

  1. Known bug, showTabs (often fixes freezes):
  • Open Command Palette Cmd+Shift+P → Preferences: Open User Settings (JSON)
  • Find "workbench.editor.showTabs": "single”
  • Change it to ”multiple" or remove the line
  • Restart Cursor
  1. Safe mode test (isolate extensions):
  • In terminal run:
    cursor --disable-extensions
  • Does the terminal work? Do files open?
  1. Check disk space:
  • Chat history loss can happen if space is low during updates
  • Keep at least 10-15 GB free
  1. If still broken, reset app data:
  • Close Cursor first, then run:
    cd ~/Library/Application\ Support
    mv Cursor Cursor.old
  • Restart Cursor, it will create a fresh profile

Please try these and tell me which step helps. If none, open Help > Toggle Developer Tools and share console errors when opening terminal or loading extensions.
