Hi guys! I am currently experiencing problems with opening files on my 2014 Macbook Pro. When I double click to open any sort of file; mp3, jpg, docx etc. is pops up with the "file is damaged move to trash". The weird thing is, that I can open the files in preview or through their respective apps like Quicktime and Word. So I know for sure that the files aren't damaged. Is there anyway to resolve this? I've tried googling my way around and done the basic troubleshooting things like resetting SMC, PRAM and messing around with some settings. I am currently running the latest version of Sierra. Even these freshly taken screenshots couldn't be opened normally.
