I've just bought a new 13" Macbook Pro which came with OSX 10.9 Mavericks (I've still been using OSX 10.6 on my Mac Pro for several reasons, so I don't have much previous experience with Mavericks). The problem is that I ran Text Edit to create a couple of documents and keep getting the following error now and again: You don't have permission to write to the folder that the file "name of file" is in. Your changes will not be saved until the problem is resolved. This doesn't make sense, because I'm saving the files to the Finder desktop, and I've logged in as usual. I only recently (yesterday) received the computer, so I can't have messed it up this much already What's the reason for this and is there a solution?
