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.
I've been having the same problem occuring often since I activated Smart Sync. The temporary fix is to reset QuickLook in Terminal with this command:
qlmanage -r
I just hope this will be fixed soon, otherwise I'll switch back to the Plus plan because Smart Sync was the main reason why I upgraded to Pro.
