I have a puzzling problem with my 2011 mac mini. I have been gradually losing hard disk space slowly since installing my SSD a month or so ago I have a 120GB sandisk extreme and it started at 83GB after everything was installed. Its down to 78GB and I havent installed a thing since. I have cleared out browser cache's and everything I could think of. I have an external 1.5TB drive that I store everything including pictures, itunes library and iphoto pictures on. Everything but the programs are on external. First thing I notice is when I go into about my mac its showing 7GB pictures, all my pictures are on external so that confuses me. I am new to MAC, only had one since Feb of this year. I can't for the life of me figure out why I am steadily losing space. Any help will be greatly appriciated. Thanks!
