One of my Mac devices doesn't sync content from my Dropbox folder online.

I was about to drop you a note to say that something appears to be happening -- I had a 'conflicted copy' from the Laptop appear on my computer, which makes me wonder if all those blue cirecles are dropbox trying to catch up wtih itself. I've deleted the conflicted copy on the computer version, as it's an old one, but that hasn't gone through to the laptop yet. I wondered: is there a way of signing out, deleting all the files from my laptop, then signing in so that Dropbox has to rebuild itself completely? I'll make contact with your support team. Thank you for your efforts!
