okay, i got my macbook almost a month ago and it is my first mac i abbbbbsolutely love it i learn new things every single day.But i do have alittle problem, since i got it i don' think i have been able to update, a couple weeks ago or a week ago when the new security update was released i ran the software update and it didn't find anything it said "that my software was up to date". I went to the apple website and downloaded it manually. When i tried to install it it said that the volume did not meet the requirements for the update.what is that supposed to mean? i am lost. now with the new battery update, same thing, i ran the software update and it says that my system is up to date. what is going on? any one has an idea? by the way its a macbook C2D and i am the only user...
