Hi! I am new to using this (or any kind) of forum for asking my questions directly. Although I have used it many times just searching and finding the answers I needed. But I have a problem with my Macbook Air that I cannot find a solution. I tried to install sometime ago a virtual machine (I do remember installing VirtualBox but I am not sure that was the only trial I did - DUMB, OK, I KNOW!). Now I simply cannot free the space anymore. Whenever I go to the Storage option on "About this Mac" and my Other files are ginormous! I already deleted everything, music, pictures, videos, ALL my files are not in my computer anymore, I also emptied trash, have been through the "operation cannot be completed because you dont have permission" thing and over it.... Meaning.. I did it all, I think. But while looking for something I did find in my Library a folder from VirtualBox and then I remembered that it was when I installed this thing that my Macbook changed forever. Can anyone help me with this please? Is it possible that there is a virtual machine hiding somewhere in my computer?
