Dropbox keeps crashing and restarting itself in an infinite crash loop

Hi Lusil,

There is no firewall or Antivirus blocking Dropbox.

There is no error message, Dropbox just crashes and restarts, and crashes and restart in a loop.

There are log messages in Console that indicate something might be wrong - this is how it looks right after the crash.

Hello,

I'm also experiencing this problem. I've tried configuring my firewall to allow Dropbox, and disabling the firewall altogether. I have no other antivirus programs. I ran the terminal command to check for symlinks, but there were none. I also uninstalled and reinstalled the app.

Most of the time the desktop app will just open and crash on loop. If I quit the app while it's booting, I receive this message. Any personal information has been replaced with [removed].
