I'm looking at my mac mini and mac pro screens side by side and can't get the columns to match up. I keep my movies in a separate folder for each title. I'm looking for all my .mkv movies. On the mini the columns I selected are name, size and kind. If I click on size it arranges them top to bottom or bottom to top. On the Macpro I see the same presentation but there is not a vertical line separating the column headers and I can't select the order of anything; it's all alphabetic by name. I've gone through preferences and set them up identically. What am I missing? Thanks in advance. Update: VIEW>ARRANGE BY>NONE Doh!
