Hi all, Was a Windows 7 fan, but sometimes the glass IS greener on the other side I recently bought a Macbook Pro 15" 2.3 Ghz (2012). It is currently on version 10.7.4 and I am trying to update to 10.7.5 to reinstall my iPhoto. But when I go to "Software Update" it shows my Mac is up-to-date. I downloaded Update 10.7.5 but it wont update because "The volume dosn't meet the requirements". What are the requirements? Any other way to update?
