I recently purchased me a Macbook. I don't have too much on the computer and for some reason it's telling me that I need to free some space on my hard drive in order to download. When I went into the apple icon on the left hand corner and under disk utility, it says that I have plenty of space available to download. Why is my computer telling me that I don't have enough free space? I even deleted some of the documents that I had on my computer to see if that was the problem. Please help!!
