I'm using the new macOS on beta, and the Dropbox app keeps crashing, and asks to restart.

same here! 

This is the exact behavior I am seeing with the version marked as solution. 

This didn't work out the gate for me but after giving Terminal Full Disk Access in MacOS and then running

sudo rm -rf ~/Dropbox
sudo rm -rf ~/.dropbox
sudo rm -rf ~/Library/Application\ Support/Dropbox
sudo rm -rf ~/Library/DropboxHelperTools
sudo rm -rf /Library/DropboxHelperTools

I was able to execute the command and install the new beta version of Dropbox. Seems to be up and running just fine, everything re-synced and no issues yet.

Same issue here. How hard can it be to test on the beta BEFORE it releases to the public?

Greetings again,

I did try doing the entire remove on my MacBook M4 with the sudo commands, and reinstalled Dropbox with a fresh download … same issue.  😭

HOWEVER … when I installed macOS 26 beta 1 on my MacBook M1 … Dropbox worked fine!   But no joy on my M4!

I hope that helps,

I tried using the beta version as suggested by drp242​ (after doing a full rm of everything) and unfortunately that was no bueno.

So, I guess I'll wait for the Dropbox team to work their magic!

Did you find a workaround mate! I stupidly thought I was downloading the beta for OS26 to a partition on my main computer (thankfully I have a second in command so all is safe re Dropbox files) the only desktop app (understandable) I’m having ache with is Dropbox desktop. Cheers 

Great news — Beta Build 227.3.4638 is now working perfectly on my MacBook Air M2 running macOS Tahoe 26.0 Beta (25A5279m). Thank you for the prompt fix! Much appreciated.

And where would I download Dropbox beta 227.3.4638 from?
