Popup window: “Dropbox.app” would like to access data from other apps.

Hi MarioC, thanks for letting me know more about this! 

Since you use macOS, can you please try the steps in the following Help Center article, in order to edit or turn off your accessibility settings, to see if you still get the same results?

No that article does not help at all because it refers to a dialog box which is only accessible during initial instal. Having waded all through I find this:
"If you want to edit accessibility settings after you’ve already installed Dropbox, follow the instructions for your operating system in this article." Sigh. Is now I have to go there and start again. I'll put it on the list to do.

Getting the same thing, but only started after I just upgraded to Sonoma (nothing to do with Install process or settings during install). Full Disk access was off, turned that on and said "Allow" to dialog, but don't know what I just authorized (is "access to other apps data" = allow full disk access?)

Hey joritian - could you let us know the version and status of the Dropbox desktop app as shown in your menu bar? 

Also, can you have a look at the app's preferences under the sync tab and clarify the location of your Dropbox folder? 

If you could send us a screenshot of the pop-up as well, I'd appreciate it. 

Current version is:  v191.4.4995

The status is fine (checkbox, sync up to date), although have some sync errors on a few files.

In the app preferences dropbox folder location is the main user folder.

The screenshot of the pop-up is exactly the same as the one(s) already posted in this thread.

This issue for me now seems to be corrected after giving full disk access in security as well as responding to "Allow" on the dialog.  As I mentioned in original post, wondering what "access to other apps data" presented on the dialog is the same as asking for full disk access or does this allow some additional / different access then that.  In other words is the dialog message just poorly worded or really reflects a different behavior.  Again I am no longer getting dialog as of yet, will edit, re-post if it comes back.  - Thank you

Glad to hear it's sorted now joritian 

Let us know if anything else comes up!

This worked for me, so far. Seems like a Mac issue, as you have to allow Dropbox 'to control your computer' which sounds ominous.

The fix:

Mac Settings > Privacy and Security > Accessibility > 'Allow these apps to control your computer' and toggle ON.

None of these things work. This is becoming so annoying. The dialogue box pops up like every 5-10 minutes and sometimes it pops up several times in a row. 

I take back my earlier suggestion, as it has come back for me, too. I keep clicking 'Don't Allow'. Have no idea how to get rid of it! Apologies for the earlier suggestion. The Privacy and Security > Accessibility action had no effect.

You should be clicking "Allow" instead of "Don't Allow".  This is in addition to the changes you made to the privacy and security settings.  (I was a little uncomfortable too, not because I had a security concern so much as wanting an explanation as to what I giving it permissions to do, but no answer as to yet)
