Dropbox desktop app not logging in - MacBook

Hi Andrea, 

I am still not able to log in.
However, please see below the email I have received from the support team:

If you're having connection problems or elements of the Dropbox application that are failing to load, this usually means there is an antivirus, firewall, security program, proxy or VPN blocking the Dropbox desktop client.
 
If you have any of the mentioned software running, please either add Dropbox to its whitelist, remove Dropbox from its blacklist, or temporarily disable or uninstall them to continue troubleshooting. For more information on firewalls, please see our Help Center article here:

The Dropbox client uses SSL to establish a secure connection to our servers. To ensure this is working properly, your system time should be correct and your security applications should allow Dropbox to connect. To learn more, please see our Help Center article here:

If you have a proxy set up on your computer or network, please enter your proxy host and port information into the Preferences panel of the Dropbox desktop application.
 
1) Locate the Dropbox icon and menu from the system tray (Windows) or menu bar (Mac/Linux).
2) Right-click (Windows/Linux) or click (Mac) on the icon to access the Dropbox desktop application menu.
3) Click on your profile picture or initials to the right of the search bar (Windows & Mac).
4) Select "Preferences" from the Dropbox menu. Select the "Proxies" submenu or tab.
 
Dropbox proxy settings allow you to set the proxy type, server, port, and login information. For example, a common port for proxies is 8080.
 
Dropbox can also fail to connect due to proxy settings which may have been changed either by other programs or by your network administrator. If you're having connection problems even though you haven't set up a proxy server, try going to the Preferences panel as described above and setting your Dropbox proxy settings to "No proxy." If you have set up a proxy server, please double-check that your system's proxy settings are still correct.
 
For more information on proxies, view the Dropbox Help Center article here:

If the issue persists, it is possible that the issue you are seeing is due to an antivirus or other type of security program blocking Dropbox from connecting to our servers.
 
To resolve this issue, please try temporarily disabling or uninstalling your antivirus or security program, and then restart your computer.
 
If the issue is resolved after temporarily disabling or uninstalling your antivirus or security program, you should ensure that you configure these applications not to block Dropbox if you choose to reinstall these.
 
You should also ensure that your local network connection settings allow access to Dropbox domains. If you are on a corporate network and are not sure if the Dropbox domains are accessible on this network, you may need to contact your company's network administrator or IT. You can view this list of domains used by Dropbox on the Dropbox Help Center article here:

Do let me know if any of the above helps you. I'm not sure why mine doesn't work still.
