Hi there, sspilleman, welcome to our Community!
How long has this been happening for? Can you try an advanced reinstall using the steps provided in this Help Center article?
I'll be waiting for your updates!
Hi Megan, thanks,
For me the problem immediately occurred right after login after updating to Tahoe 26.4 (Beta 1). This update was already available for a couple of days but I only decided to update this morning. The article you are referring to is covering windows, Im on a mac.
I already tried removing the application (/Applications/Dropbox.app) and reinstalling it before creating this ticket.

Hey sspilleman, I hope I can jump in here as well.
The article Megan linked in her reply includes steps for Mac computers as well.
You'll find the option to switch from the Windows steps to the Mac ones right above the Windows steps:
I hope this helps!
I'll await the fix, I already reinstalled. 100% convinced this is related to the macOS update
- Hannah
Hey sspilleman, since this is a permissions error which indeed could have been caused by your OS update, it's very unlikely to resolve itself.
That's why I've gone ahead and sent you an email, so we can investigate this further.
I meant it will be resolved by a future update to the application, not by itself

Hi sspilleman thanks for reporting this. Our engineering team are aware and investigating, I'll report back once we have an update.
This just happened to me as well after I installed the latest 26.4 Beta OS update.
Still exists afte the latest 26.4 beta update (25E5218f). I also just tried installing the latest dropbox client. Still broken

Hi sspilleman. I'm from the Dropbox engineering team. We've been investigating this issue and early findings suggest that external drives are becoming read-only upon update to macOS 26.4 Beta. This prevents the Dropbox app from working correctly if your Dropbox folder is stored on the external drive as we don't have the permissions to make necessary changes to files within your Dropbox folder. We're currently escalating with Apple and hoping for a fix on their side.
Please let us know if you are experiencing this issue while your Dropbox folder is on the default volume of your device.
