OS: Mac OSX High Sierra (10.13.4)
I just now upgraded from Dropbox Plus to Dropbox Professional.
Then I clicked "Enable Smart Sync."
Then I clicked "Open Preferences."
Then in Preferences pane, I clicked "Allow" (to the right of "System software from developer 'Dropbox, Inc.' was blocked from loading.")
Then nothing happens.
So Smart Sync will not activate.
How do I fix this?
Thanks in advance!
