Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. I can see the crash screenshot, code 5. That usually means the renderer process crashed. A few users on 2.6.x have hit this too. A couple things that may help:

  1. Don’t keep super long chats. If the chat has a lot of changed files, start a new one. This is the most common cause.

  2. Check that your project isn’t inside an iCloud folder (Desktop, Documents). If it is, move it to something like ~/dev.

  3. Try without extensions:

    cursor --disable-extensions
    
  4. Disable GPU acceleration:

    cursor --disable-gpu
    
  5. Reset Cursor data (your backup will stay):

    cd ~/Library/Application\ Support/
    mv Cursor CursorBackup
    

If none of that helps, please send:

  • Logs: Help > Open Logs Folder, the main.log file around the crash time
  • A screenshot from Cmd+Shift+P > Developer: Open Process Explorer right before the crash
  • Your list of installed extensions
  • Whether you use MCP servers

The team knows code 5 crashes have been happening more often in recent versions. Your report helps us prioritize. Let me know how it goes.
