24 Hours with Strongsync » Dropbox
Summary: When it works, it’s great. When it doesn’t, it’s impenetrable.
Tonight I tried to download a large folder from Dropbox with about 800 MB of video files in it.
It clearly stalled. When that happened, there’s literally nothing that you can do.
Eventually this message came from Finder:

I’ve restarted Finder. I’ve restarted the app. I’ve unchecked all of the “Finder Extensions” for Strongsync. I even quit the “StrongsyncFileProvider” process via Activity Monitor.
Then I relaunched Strongsync and restarted Finder again.
The Strongsync Dropbox folder is empty.
I quit everything again. I got the same error message again.
I quit everything a third time.
This time when Strongsync re-launched, it seemed to work fine.
You know how when iCloud Drive works, it’s invisible and seamless, but when it works, there’s really nothing to do but hope that it will start working again?
Strongsync is like that, except for Dropbox.
I’ll keep using it for Google Drive, for now, as my Google Drive needs are light, but I don’t think I’ll be using it for Dropbox, where I keep most of my life.
The Dropbox app, despite not being Apple Silicon native and despite being a terrible and poorly written app which I don’t feel great about having installed on my Mac, is at least more useful in telling me what Dropbox is doing, and giving me more control over the process. (Most of the time. Dropbox has its own impenetrableness at times, too.)
Fortunately I’m perfectly happy to live with a small external drive affixed to my laptop.
