Hi all - I got my refurb MBA (13"/128/4GB) on Friday and did the initial battery calibration with the MBA being fully drained yesterday and left off another 6 hours before charging overnight. Anyway, when I turned it on today I noticed that my trash had 52 files in it -- 50 of these are various fonts and of the other 2 a document called "OfficeSetupSemaphore" and a Unix Executable FIle called "wkresources". I am kind of freaked out by this and wondering what to do. Any suggestions/tips? Thanks so much in advance.
