Dropbox Finder integration breaks Quick Look and thumbnails - Mac OS Mojave 10.14

Guys over at St. Clair Software have a great fix for this:

It turns out that a new beta of DropBox installs its own QuickLook generator plugin that overrides the system-supplied plugin for generating a number of file and image formats – including those MS Office files. OK, fine – just delete it, right? That worked until he restarted his Mac, then DropBox launched at login and promptly (and silently) reinstalled its QuickLook plugin again. I guess it knows what’s best for us, eh?

After a little thought, we arrived at this solution:

1. Delete the DropBox QuickLook generator plugin
2. Create an empty file at that location to prevent DropBox from reinstalling it

Fortunately, QuickLook is smart enough to realize that an empty file isn’t going to help it generate previews, and just defaults back to the other plugins it has. Problem solved!

The easiest way to do this is to open Terminal and execute these three commands:

rm -r ~/Library/QuickLook/DropboxQL.qlgenerator
touch ~/Library/QuickLook/DropboxQL.qlgenerator
qlmanage -r

A nice simple solution once you get it figured out. I imagine this is one of those problems that’s going to crop up for a lot of people but isn’t quite obnoxious enough to get them to hunt down a solution. So there you go

Here's what I did:

1. Turn OFF "Finder Integration" in DB preferences & Restart to check to see if QL is working. (Mine wasn't so I continued to #2)
2. Open Terminal and typed in commands from above & restarted
3. My QL was now working! So then, as an experiment, I went back and tuned ON finder Integration in DB.
4. Now BOTH are operating correctly. Let's see how long this will last :) 

But also note that, unfortunately, QL will still NOT work if a file is not local on your hard drive. Still, I'll take what I can get.
