Hey, thanks for the report.

This is a known issue that affects some macOS users. Let’s try to narrow down the cause:

  1. Check if your project is in an iCloud-synced folder (Desktop, Documents, etc.). If it is, move it to a local path like ~/dev. This fixed crash code 5 for a few users.

  2. Test without extensions:

cursor --disable-extensions

If the crashes stop, turn extensions back on one by one to find the culprit.

  1. Reset Cursor data (it will create a backup of your current config):
cd ~/Library/Application\ Support/
mv Cursor CursorBackup

Then restart Cursor.

  1. Disable GPU hardware acceleration:
cursor --disable-gpu

If none of this helps, I’ll need a few things to pass to the team:

  • Logs from Help > Open Logs Folder, specifically main.log around the time of the crash
  • Help > Toggle Developer Tools > Console, a screenshot of any errors
  • Whether you’re using a VPN or proxy
  • Your list of installed extensions
  • Whether you’re using any MCP servers
