Hey all, I will make this as short and precise as I can. As far as I can see, someone on my work mac right clicked on the 'Downloads' folder and set the 'Open With' option to 'Preview'. As such, when the icon is clicked every item in the Downloads folder opens in preview (massive pain) and there are issues with the folder working on the dock. I tried changing the 'open with' option on the Downloads folder myself but there isn't anything appropriate to change it back to. I assumed finder but that isnt an option. Any ideas guys, thanks in advance for reading this.
