Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. I see the screenshot with the error The window terminated unexpectedly (reason: 'crashed', code: '6'). Each new window should start its renderer cleanly, so this isn’t intended behavior and it’s not something in your setup. It’s an issue we’re tracking, but I can’t share an ETA yet.

Here are a few workarounds that help keep things stable:

  1. Fully quit Cmd+Q and restart. This clears accumulated resources, and new windows usually open normally again for a while.
  2. Add your build output folders to files.watcherExclude to slow down the buildup:
    "files.watcherExclude": {
  "**/dist/**": true,
  "**/build/**": true,
  "**/.next/**": true,
  "**/node_modules/**": true
}
  3. As a last resort, start Cursor from Terminal after running ulimit -n 65536.

To help us diagnose, please share the crash report: Console.app → Diagnostic Reports → a file like Cursor Helper (Renderer)-*.ips (you can rename it to .txt so you can attach it here). This is especially helpful since you’re on an Intel Mac, and most earlier reports were on arm64.

I’ll post an update in the thread when we have one.

Hey @Xiaotao_Lin

Would be really interested to know if this thread applies to you (does the crash happen while working in large Typescript/Javscript repos?)

They look somewhat similar, I can give it a try.
