Cannot create the required folder
I am on a Mac with Yosemite, and I plan to migrate from Aperture (BTW, thanks, Apple!) to something else, and one of the options is LR. So, I downloaded the trial version but when launching it presents a window with a fatal error "Cannot create required folder). I am the sole user on my system, I have administrator privileges, I have tried to create a folder in the exact place where LR can't, and I created it with no error messages.. so, what's wrong? I add a copy of my error screen
