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

I experience the same issue.

I deleted the Dropbox app and also the  folders ind /Library/Application Support and reinstalled from the offline installer file Dropbox 234.4.5591.arm64.dmg

Startup is not progressing for 15 Minutes.

MacOS 26.0.1 (25A362)

MacBook Air M2 13" 2022

having the same issue on my mac

Sorry to hear this, Markuswalz_eu. From what I get, you started experiencing this issue right after updating your device to the new OS. Is this right?

Also, when saying that you’ve deleted the folders in /Library/Application, do you mean that you’ve already performed an advanced reinstall of the Dropbox app?

Hey AlbronHana. Similarly to the previous users, did you also notice this behavior after upgrading your computer to the new macOS?

Can you clarify the Dropbox app version that you’re currently running?

Yes I performed an advanced reinstall. The problems startet yesterday. On my M1 MacMini all is fine with my "old" dropbox version, I used before installation of the 26.01 Tahoe Update. 

Version of Dropbox Client 234.4.5591

But... Today I could perform the full Installation, unlike yesterday. All is working fine again.

Mysteriuos Miracle :-)

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

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.

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.

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

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?
