Hello. I recently got a 2015 13" rMBP and it sometimes is a bit slow to create new folders. Also deleting something sometimes is a bit slow. But then it gets faster. Strange. Anyway, here is a presentation of it, as I don't have the correct words for it. https://www.dropbox.com/s/mlvv49ebse44e4h/newRmbpSlowFinderActions.mov?dl=0 Anyone have a clue?
