Smart Sync and Quick Preview on Mac
Smart Sync causes my quick preview function (spacebar) to not function properly on my Mac. I can't preview thumbnails, or quick preview any videos or photos. Any ideas why this happens?
Likely because you're trying to preview a file that doesn't exist on your computer.
When you set a file to Online Only, the only thing that's left of that file on your computer is the necessary information to make it appear in the folder. Since there's no content in the file, your OS (nor any other program) is able to preview it.
Remember, when you set a file to Online Only, the file is removed from the computer leaving behind only a marker file. In order to access that file, whether it be to open and edit it or simply preview it, the file needs to be on the computer (Smart Sync doesn't allow you to open files directly from the Dropbox servers). When you open a file, it's synced back to your local drive and then opened as normal. When you're done with the file, if you want it to be online-only again, you need to mark it as such.
Our team has been using the Smart Sync and so far it has worked really well!
However we noticed that after starting using Smart Sync on High Sierra, all of us have the issue that Finder stops showing the preview image when hitting space bar on files. You need to relaunch the Finder all the time to get it back to working.
We suspect that it's somehow related to dropbox smart sync, because many time I notice this happening is when I'm browsing files on a dropbox folder that have all or some of the images on "online only" mode.
Anyone else experiencing the same issues? Any solutions out there?

Dropbox StaffHey Sanchez,
Does not seem to matter is it updated or a clean install. Most of the Macs in our team are updated to high sierra but few are clean installed. I just clean installed the High Sierra few days ago and installed the latest dropbox client but the same thing happens.
It happens every time when you browse preview images in finder Online Only folders, it shows few preview images and then stops showing and you have to force restart the finder to get it working again.
Let me know if you think of anything to try.
