I'm currently running OS X 10.11.5 on an early-2015 13" MBP, and noticed that the graphical buttons for "back", "view", "arrange by" etc. on my Finder toolbar have been replaced with plain text (see screenshot). Restarting didn't help, nor did updating from 10.11.4 to 10.11.5. I've been unable to find any descriptions of this exact problem online - the closest was a thread from 2008 about some missing icons in Finder, which was seemingly caused by a corrupted Finder plist. Could that be the case here too? If yes, how can I fix this? If no, what else could be the problem?
