Been using cursor for about six months and love this product.

However, just setup a new mac running Sequoia 15.3 and for some reason Cursor is completely unable to modify files in a project I’ve been working on.

Beyond frustrating.

Attached some screenshots below, no idea how to fix this?

The error I see is “Error: EROFS: read-only file system,”

Hey, it seems you don’t have enough permissions for the directory you’re working in. Try changing the permissions for the folder using this command in the terminal: ⁠

`sudo chmod +x path/to/folder`.

Also, check if Cursor has full disk access. To do this, open System Preferences, go to `Privacy & Security > Full Disk Access`.
