Hi superudi,

mine doesn't start neither (reboot or restarting dropbox doesn't help)

OS: MacOS Ventura 13.3.1

Hey andydp, thanks for bringing this to our attention.

Is it possible that you might have any security apps installed on your computer, like a VPN, antivirus, firewall etc. that might be blocking the Dropbox app?

If you do, can you disable them temporarily, to see if that helps?

no joy

when I disable my antivirus, it does start but:

- it claims it can't sync (icon with cross in task bar on Mac)

- it does sync 🙂

and quite some dropbox processes running:

Hi andydp, could you try reinstalling the app, without uninstalling it first, using this link, to see if this helps?

looks like that did the trick 🙂

thx

Hi Emmet

I tried everything – reinstalling the app, restart, system update – nothing solves the problem.

I don't have access to my personal Dropbox for more than two months now from my Macbook.

Please help.

Hey superudi, sorry to hear about this.

May we reach out via email to have a further look internally? 

Yes I would love that. Do you need my email address? I guess you already have it 

Thanks for the coopearation superudi 

I've just sent you an email to the email address that's associated with your profile here, on our Community. 

Whenever you get the chance, please have a look at your inbox and we'll take it from there. 

Reinstalling Dropbox using the link also worked for me.
