I upgraded the Dropbox app on my Mac when it prompted me to upgrade and I noticed fileproviderd (AppleOS) went nutso on my CPU immediately. I woke up this morning and it was the same way.
Dropbox support was responsive but not helpful. Then I decided to redownload and reinstall the app and the problem just went away.
I'd like to switch away from Dropbox to something opensource, but it has been so useful from Linux, AppleOS and Android. Suggestions welcome!
