The Dropbox app doesn't start up on macOS Tahoe 26.0.1.

Hey koekoe!

Just popping in to see if you've had a chance to look at our last message. Still need help? We're all ears! If the issue is sorted, let us know what worked out for you.

Hey koekoe, let's jump right into this!

Just to make sure I'm aligned with you, when you say that the app doesn't start do you mean that it remains unresponsive when you click the little Dropbox icon on your menu bar? If you get any errors feel free to let me know. 

Can you also hover your mouse over the icon, and let me know the version of the app that you're currently using?

If you haven't tried already, can you perform an advanced reinstall and let me know if the behavior remains the same? 

Let me know more, and we'll take it from there!

Having the same issue. Dropbox non-functional on MacOS Tahoe 26.1. Dropbox is about to lose a ton of users. 

Uninstalling and re-installing Dropbox doesn't work. Issue remains.

Hey Oriion - sorry to hear about this.

The operating system (Mac OS Beta) you are running is not currently a fully tested or supported environment for the Dropbox desktop application. 

While we support a variety of operating systems, we are unable to support these versions until they are officially classified as stable.

I wish I had a better answer than this and please let me know if you have anything else to ask or add. 

Nancy​ or Walter​ been having this same problem with Dropbox. I contacted support with the logs it generated within a text file in regards to the error, and they just told me to check the FAQ or community posts and that the support ticket will be closed. Been frustrated trying to figure out how this can be fixed... I have the newest version of Dropbox and I'm having issues on macOS 26.2 Beta. Although judging by other users, it seems like it's an issue in 26.1 public release as well. I did try restarting my Mac as well as reinstalling Dropbox multiple times (and wiping its associated files for a fresh restart). Any help with this would be much appreciated!

Thanks for keeping us in the loop on this rrstockertx - much appreciated.

Can you please clarify if you're getting any particular error or if the app is just not responding?

Have you tried reaching out to our support team by the way? 

OK, completed the uninstall including the TERMINAL code I was told to enter and still not working.  I am happy to pay someone for a tech support call and this is hurting my and my work. Thanks, Roy

Hi from me as well, rrstockertx. I’m sorry to hear the issue persists. 

If you haven’t done this already, please go ahead and perform an advanced reinstall next. 

Let me know how that goes, and we’ll take it from there.

I have updated to Tahoe v26.1, and it is still not working. I can't get a desktop even to work, and I am still having issues.  YES, I have uninstalled it and reinstalled, but have not heard from Dropbox that the issues are fixed.  Any other options, please? I have installed Version # 236.4.5918 - this has been a nightmare and have never had an issue like this for over 10yrs. Please respond someone.

Excellent, Markuswalz_eu! Thanks for letting me know, and if anything else comes up, I'll be right here.
