Cursor IDE

Describe the Bug

I’m running into a really frustrating issue with Cursor that I’m hoping someone else has experienced and found a solution for.

The Problem:

This has happened 4-5 times now, and it seems like Cursor is somehow causing my entire Finder and Quick Look to completely stop responding. When this happens:

Can’t open ANY files through Finder

Can’t delete ANY files (have to resort to terminal with rm -rf)

Space bar preview (Quick Look) completely broken

Basically my entire file system interaction through the GUI becomes unusable

Current “Solution”:
The only way I’ve found to fix this is to completely nuke Cursor from my system - and I mean COMPLETELY. I have to:

Remove the Cursor application

Hunt down and delete all Cursor-related files (including hidden ones)

Restart my machine

Then reinstall Cursor from scratch

Only after this nuclear approach does my Finder start working again.

Trigger:
I’ve noticed this mostly happens when I’m working with screenshots within Cursor, though I’m not 100% certain that’s the exact trigger.

Setup:
Mac M2 Pro Max
Latest version of Cursor

Has anyone else experienced this? It’s making Cursor pretty much unusable for me since I can’t risk having my entire file system GUI break randomly. Any ideas what might be causing this or potential fixes that don’t involve completely reinstalling every time?

Yes - Cursor is unusable

Hey, thanks for the report. This is really strange behavior, Finder crashing isn’t normal, and I understand why that makes Cursor unusable.

It could be macOS file permission issues or a conflict with QuickLook plugins. Since it’s tied to screenshots, there might be a problem with how Cursor handles previews or temporary files.

Before a “nuclear” reinstall, please try:

  1. Relaunch Finder without removing Cursor: run sudo killall Finder in Terminal, or hold Option and right‑click the Finder icon in the Dock → Relaunch
  2. Check for conflicting QuickLook plugins: qlmanage -m to see what’s loaded
  3. Temporarily run Cursor with reduced permissions and see if the issue persists

If none of this helps, let me know and I’ll pass it to the developers.
