Finder integrations not working for OneDrive, Google Drive, Dropbox
Since updating my Mid-2010 MPB from El Capitan to High Sierra, I no longer have status icons on the files in any of my cloud services in the Finder. OneDrive, Google Drive, and Dropbox folders all appear just as any other folder. There's no green checks to show sync status, etc.
My other Finder integrations are working fine.
The one other anomaly is that all mounted drives are showing up as just round circles in Sidebar, not as their icons. That was also happening before my update to 10.13.
I know I could uninstall and reinstall them all, but since it's all of them I can't imagine all of them are having the exact same problem. Also, I don't want to have to re-download all that data — and I know that at least two of those services delete all the files if the app is uninstalled.
Thoughts?
