Dropbox Now Requires Authentication in macOS High Sierra (10.13.4)?

[jdmcs]

I recently clean installed High Sierra and the Dropbox app on my MacBook Air (due to replacing the SSD), and then used the Combo Updater to install the 10.3.4 update.

Now, every time I restart, the Dropbox app needs authentication to do something. (The dialog box simply says authentication is needed for Dropbox "to work".) I tried turning off Finder integration (didn't stop it), and giving Dropbox control permission in the Accessibility Control Panel (also didn't stop it).

Dropbox isn't doing this on my Mac Pro (still at 10.13.3), and wasn't on my MacBook Air (at 10.13.3) before the reinstall.

Does 10.13.4 legitimately now require Dropbox to authenticate before it can run? (And can I turn some feature off to allow Dropbox to run without authentication?) Or is this a symptom that Dropbox failed to install properly, and it keeps attempting to install a component on startup?

Sounds like it has not installed correctly.

I'd download and reinstall from www.dropbox.com/downloading

I am running MacOS 10.13.3, and found that the Dropbox Installer simply failed in an SSL handshake.  When I ran it by hand in the Terminal, I saw:

$ /Volumes/Dropbox\ Installer/Dropbox.app/Contents/MacOS/Dropbox\ Installer 
2018-03-31 18:02:43.367 Dropbox Installer[10903:720630] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)
2018-03-31 18:02:43.395 Dropbox Installer[10903:720647] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)
<snip many repetitions .../>

Looked to me like the stub Installer app was having trouble downloaded the full installation, so I tried this:

$ strings /Volumes/Dropbox\ Installer/Dropbox.app/Contents/MacOS/Dropbox\ Installer | grep http
https://www.dropbox.com/downloading?plat=mac&full=1
https://www.dropbox.com/download?plat=mac&meta=1&build=%@
https://www.dropbox.com/installer_funnel?

That first URL looked promising, and when I copy-and-pasted it into the browser, it downloaded "Dropbox 46.4.65.dmg".  I double-clicked on that to mount it, double-clicked on the seemingly-identical Dropbox Installer in that folder, and all was well.

Looks as if the Installer app needs a new approach to get out to do its download.

Success, in any event.

I tried reinstalling Dropbox, and that unfortunately did not resolve my issue.

Before uninstalling, Dropbox is saying that it is version v46.4.65

To uninstall, I followed the directions for Mac here: https://www.dropbox.com/help/desktop-web/uninstall-dropbox

• I opted to leave the Dropbox folder behind.
• I tried to uninstall the Dropbox contextual menu, but there was not a DropboxHelperTools under /Library (something tells me that this might be the root of my problem)
• I left the application preferences behind.

I used the link that Mark provided to download a new installer. I followed the usual process.

On first launch, I received the "Please enter your computer password for Dropbox to work properly" system dialog. I expected this one.

After re-installation completed, I went to /Library to check for DropboxHelperTools. It was not there. And after a reboot, I received the "Please enter your computer password for Dropbox to work properly" system dialog. I confirmed that I reinstalled the same version of Dropbox (46.4.65).

I'm going to go out on a limb and say that Dropbox is failing to install DropboxHelperTools under macOS 10.3.4... or my MacBook Air.
