Hi leeharris and all support staff,

Again something is "unknown" for Dropbox!!! Actually, this error (ENXIO with code 6) means that for some reason the scheduled operation cannot be performed or not supported on particular device in general (partition in the particular case). The reason can be some incompatibility, but again - without info where new folder creation trying has been performed (where the 'at' handle points to) that fails and the underlying partition type (and mounting options could be helpful) nothing concrete can be said. Invite your development team to put some more information when unhandled exception brings up. If I have to bet, Dropbox application tries to create temporary folder on a partition where such creation is not supported and not allowed. Most probably some hidden bug, in configuration management, that comes up from time to time, and forces folder creation on "unusual" places instead of the normal one.

leeharris, To flush up entire configuration and start on clear, perform advanced reinstall if nothing else helps. Since the main temporary dir already exists, it's likely application and/or computer reboot to help. Did you try this? Try in advance...

Good luck.

Hey leeharris, sorry to see that you're having this issue.

Since you posted on a thread that was about a different issue, I moved your post to a more relevant thread.

Can you give us some more info about when this issue started happening?

Was it after you updated your computer to Sonoma?

Also, did you update your Dropbox to the new Dropbox for macOS on File Provider?

Hey dlee10, sorry to see you're having this issue with the Dropbox desktop app.

Can you please click on the blue hyperlink on the error and send us a copy or screenshot of the full error log?

I am experiencing this same issue in Windows 10 but removing Dropbox from C:\Users\username\AppData\Local did not solve the problem. Dropbox still won't start. I posted my similar issue here: https://www.dropboxforum.com/t5/Apps-and-Installations/Couldn-t-start-Dropbox-permissions-error/m-p/616430#M43261

Any advice is welcome, thank you!

Thank you very much, for me (in mac) after hours of searching, uninstalling and installing several times, I finally found your answer in the forum.

It was as easy as just:

- *with dorpbox installed but closed 
- open terminal
- copy paste: 

rm -rf ~/.dropbox

- press enter

- open Dropbox 
- working like nothing wrong ever happened 

Thanks very much Здравко!, this did the trick.

One thing to add to all of this is during the installation you need to select Advanced to choose another installation directory from the default location
