Dropbox desktop app won't open after Mac OS update to Monterey 12.6

Hi Pauline Hubner, welcome to our Community! 

If I were you, I'd try exactly what you mentioned. Uninstalling the app, then re-installing it might do the trick for you. 

Can you give it a go, and let me know of any updates? Thanks a bunch! 

I am having the same issue. I tried uninstalling and reinstalling on MacOS 12.6 but now I can't even launch the driver to reinstall the application.

I am by no means a tech-type (very much 'need to know'/muddling-through basis (and lots of crossing fingers) so all that follows I see basically as some kind of weird computer alchemy/fate.

I put the Dropbox application in the bin, emptied the bin, restarted my Mac, turned off my wifi and plugged in to the internet via ethernet cable instead. I then downloaded the Dropbox for desktop app again using Safari (I had used Firefox previously - have no idea if that's relevant or not!!) and it SEEMS to now be working... the icon appears in the top menu bar and I was able to go in and deselect folders that I didn't want to sync with my machine as I used to. When I'd tried downloading the app previously, it seemed to download then I had the same problem as you i.e. the driver wouldn't even launch. Doing a fresh download using a different browser and with an arguably more stable internet connection seemed to help in my case (but maybe you've already tried that?!)

Hey Pauline, thanks for sharing your great troubleshooting! I am happy to see that the app is now working as it should.

Happy Thursday DustyDesigns, I hope you're doing well! Can you try out the steps, Pauline suggested and let me know the results? 

I am up and working again using a different method. All I needed to do was delete the application and make sure that the most recent dropbox installer was downloaded.

When using the "get app" prompt from the dropbox landing page HERE it didn't download the most up-to-date installer. After a while I found a working installer through this dropbox help page HERE.

Hi, I uninstalled drobox but it won't re-install now. Any ideas? 

Hi madzarica, what error are you getting when attempting to reinstall the app. Are you using this link to install the app?

Hey, thanks for the reply. That's the link I am using. I found instructions what to delete in order to get new installation to work. However, an update requires moving a Dropbox to a new location which is what cause the problem previously so I am not updating for now. 

What error are you experiencing currently? A screenshot showing this would help greatly.
