Hey, thanks for the report. I can see Cursor Helper processes are using a lot of resources on your M1 Mac Pro. Let’s narrow down what’s causing it.

Please try these diagnostic steps:

  1. Test without extensions:
    Run this in Terminal:
    cursor --disable-extensions
    Does the issue still happen?

  2. Process Explorer:
    Press CMD+Shift+P → “Developer: Open Process Explorer”
    Take a screenshot when CPU/memory usage is high and share it here.

  3. GlobalStorage cleanup (often helps):

    • Fully quit Cursor
    • In Finder, press CMD+Shift+G
    • Go to: ~/Library/Application Support/Cursor/User/globalStorage/
    • Rename state.vscdb and state.vscdb.backup to *.old
    • Restart Cursor

  4. Console errors:
    Help → Toggle Developer Tools → Console → screenshot any errors, if present.

Also please share:

  • Cursor version (Help → About Cursor → Copy)
  • Approx project size
  • Which extensions are installed
  • Does it happen right on launch, or after specific actions?

Let me know what you find.
