I recently setup a new Macbook. I had a few apps open, and noticed all of a sudden a Finder dialogue window that showed thousands of files being transferred to 'Movies.' I believe it said '...files being copied to Movies.' And it was in the magnitude of 10's of thousands of files.
I quickly cancelled this process because whatever it was, was not intentional. There is nothing now in the Movies folder. And this is a brand new Macbook to which I did not migrate any personal data.
Im now paranoid about what those files were, how that process started, if I have malware, etc.
For my peace of mind I want to see if it's possible to find a log of all activity in Finder that would show details about that unintentional file transfer. I tried looking at the Console application, and system.log file but Im not sure if that's the right place to look.
