Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. Let’s gather some diagnostic information to identify the cause:

Could you please share:

  • Which extensions you have installed? (Run cursor --disable-extensions from your system terminal and check if crashes still occur)
  • Before the next crash, open Process Explorer (CMD+Shift+P > Developer: Open Process Explorer) and share a screenshot showing which processes are using high CPU/memory
  • Crash logs from Console.app (search for “Cursor” around the crash time)

Quick tests to try:

  • Run without extensions: cursor --disable-extensions
  • Monitor RAM usage in Activity Monitor during your session

Many recent crashes were resolved by removing problematic extensions or fixing network security software.

Let me know what you find!

I’m facing this as well. Happened twice just today
