I have upgraded to 1TB. I have a Mac OS 10.10.1 Yosemite. I have a lot of files to upload and I left the computer open and connected to Internet all night. But, this morging when go to "rencently updated" in my Dropbox desktop, the last file says 15 hours ago. This means that during the night it has not been syncing. How can I make Dropbox sync during the night?
