Cursor IDE now crashes code: '5' every 10 seconds

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The IDE is replaced by a modal:
The window terminated unexpectedly (reason: ‘crashed’,
code: ‘5’)

I click “Reopen” and then tell the agent to “continue”. It makes some progress and then, sometimes within seconds, it crashes again.

Cursor support was contacted a week ago and I’ve still not heard back.

I’m on a 2021 MacBook Pro with 16GB running Sequoia 15.7.3

Cursor, I think, is up to date:

Steps to Reproduce

No matter what I do or what Agent I use the crashes continue. Sometimes they only happen after a few minutes of use but other times every few seconds. The Mac’s Activity Monitor does not show anything unusual with CPU or memory.

Expected Behavior

Cursor was never crashing for over 6 months of use. This started happening about a month ago.

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

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

The team is aware of the issue. Let me know what you find from the steps above.

It’s interesting that the crashes seem to have stopped after I started a new chat. The previous chat had 31+ files listed as having been modified - all of them had been committed in over dozens of commits over a couple of weeks.

Since I started a new chat, on exactly the same project, the crashes have not reappeared.
