I am having an issue with Dropbox not starting on my Mac computer. Can you help?

Level 2

I upgraded to a new Mac with Sierra for the operating system. After migrating my old information from my previous older Mac I tried to run dropbox and I get the following error when Dropbox tries to open.


[get_extra_trace_info failed]
Traceback (most recent call last):
  File "dropbox/client/main.pyo", line 823, in boot_error
  File "dropbox/client/main.pyo", line 5257, in get_dropbox_path
AttributeError: 'NoneType' object has no attribute 'get_dropbox_path'

Original traceback:

Traceback (most recent call last):
  File "dropbox/client/main.pyo", line 5536, in main_startup
  File "dropbox/client/main.pyo", line 2030, in run
  File "dropbox/client/main.pyo", line 1102, in startup_low

I've tried unlinking my device. Uninstalling and attempting to reinstall Dropbox. And did the steps for advanced users using Terminal. But I continue to get the same error when either I try to start Dropbox or install it.

Re: Dropbox won't start

Hi there,
Thanks for posting in our forum! 
Can you verify that you’ve installed the latest stable build of the Dropbox desktop application (16.4.30)? 
I would like to see the full content of the error message. I encourage you to write to us at and include the full error message so that we can investigate this issue.
