Dropbox stuck at "Starting"

Hey samurai023 - I am sorry to hear about this. Let's see what could be causing this now.

First off, bear in mind that often, the antivirus or security software on your computer blocks Dropbox from completing the startup process. To see if this is the issue, follow these steps:

A. Temporarily disable any antivirus or security programs on your computer.

B. Reinstall the Dropbox application using our offline installer.

I hope this helps and please keep me posted. Thank you.

Thank you very much for prompt reply.

Actually I am not sure I have anti-virus software or not. I googled on how to check this on mac, but found nothing useful. But even if I do have anti-virus software, it causes no such problem in the past three years.

I have been using offline installer. 

Do you have any other clue? Would this be a compatability issue with macOS Sierra?

Thanks for the swift response samurai023 - I appreciate it. 

In regards to the security settings that might be causing this, take a look here. Another thing I would check now is the number of the files inside your Dropbox folder as the performance of the Dropbox application starts to decline after reaching about 300,000 files.  

If that's not the case, let me know and we'll take it from there. Thanks!

@Walt3R

Thanks a lot for further instrcutions. 

I turned off anti-virus software. But it is still not working. There are 14,000 files in my Dropbox folder, much less than 300,000. So this is not the cause of my problem.

I also tried to re-isntall macOS, which does not work either.

Hey there samurai023 - sorry to hear this persists.

I have reached out to you via email to see into this issue together. Check your inbox at your earliest convenience and reply to my email to get started!

Thanks in advance for your response and cooperation so far. Have a great day ahead and talk to you via email!

Helle, I'm having the exact same problem as samurai023. I've tried to uninstall/reinstall Dropbox, change security settings, but nothing worked.

OS: macOS Sierra Version 10.12.5

Dropbox version: v52.4.58

Dropbox account: both Personal and Business.

I haven't updated my system for a while. I'm still on Sierra version 10.12.5.
