Describe the Bug

Installed this morning and was having an extremely productive first session. After making a lot of changes, and saving very frequently, I restarted the mac IDE after installing an .md spell checker. On return, ALL of my changes were gone, except for some files I deleted. I had not committed to git yet. The cursor AI looked hard the for the files, but they are gone as if they never happened. Not in trashcan either

Steps to Reproduce

Critical Bug: Saved Files Disappear on Restart

Cursor Version: 1.4.3 (Universal)
VS Code Version: 1.99.3
OS: macOS 24.5.0 (Darwin arm64)

What Happened:

  • Created and saved multiple files throughout the day
  • Used Cmd+S every 45 seconds
  • Watched files change from dot (unsaved) to X (saved)
  • Files were definitely saved to disk
  • Restarted Cursor
  • ALL saved files disappeared

Expected Behavior:

  • Saved files should persist after restart
  • Auto-save is enabled (onFocusChange)

Actual Behavior:

  • Saved files are completely deleted on restart
  • This makes Cursor unusable for development
  • Work is permanently lost

Steps to Reproduce:

  1. Create a new file in Cursor
  2. Save it (Cmd+S)
  3. Verify file exists on disk
  4. Restart Cursor
  5. File is gone

but i couldn’t reproduce it

Impact:

  • Critical: Makes Cursor unsafe for development
  • Lost entire mornings’s work
  • Cannot trust editor to preserve files

Additional Notes:

  • Auto-save setting exists in settings.json but not in UI
  • Cursor appears to be using VS Code settings
  • This suggests a bug in Cursor’s VS Code integration

This bug makes Cursor completely unusable and dangerous for development work.

Expected Behavior

Files that I create and edit are available after restart

Operating System

MacOS

Yes - Cursor is unusable

Hey, I’m sorry you encountered this issue. You can try creating files with the same names and check the timeline panel, it should have saved the last version of the file. I hope this helps you recover the files.

Thank you. I was able to piece together most of my work because of things saved here (Thanks to chatGPT):
$HOME/Library/Application Support/Cursor/User/History

But i downgraded cursor to 1.4.3 and I’m keeping a close watch on the files. This has been an extremely painful day. I will stay on this version until I hear some acknowledgement about what might have happened and if it will be addressed.

I’m glad you were able to restore your work, and thank you for the report. We’ll investigate it.
