Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This matches a known issue in v2.0.43+ on macOS.

Quick fix:

  • Open Command Palette Cmd+Shift+P → Preferences: Open User Settings (JSON)
  • Look for "workbench.editor.showTabs": "single"
  • If present, change it to ”multiple" or remove the line
  • Restart Cursor

This setting can cause freezes when opening files in recent versions and has helped several users.

If that doesn’t help:

  • Test without extensions: run cursor --disable-extensions from Terminal
  • Check for console errors: Help > Toggle Developer Tools, then try opening a file

Let me know if changing the setting fixes it.
