Running Mac OS X Lion and I can't save any images, files, create new folders or even take screenshots in any folder! This is ridiculous! I get "unexpected error (error code -50)" when I try and create a folder ANYWHERE and I get "You don't have permission to save screenshots where screenshots are saved"...well I looked it up and I learned that some others had similar issues a few years back related to permissions, I already figured it was permissions but changing permissions on the specific folders down to the SSD and user folder and desktop did nothing, it was already set as read and write anyways. I tried clicking the unlock button and unlocked it but nothing. This is ridiculous I have 15gigs of space and work to do and I get this BS error...any help? Thanks in advance!
