Couldn't Start Dropbox - macOS Monterey

[amiralin]

After installing the new macOS Monterey I am getting the below error 

Couldn't start Dropbox

This is usually because of a permissions error. Storing your home folder on a network share can also cause an error. For more information, click the help button below.

I tried to remove dropbox using instructions on the website and re-install using advance install and still see the error.

Following these permissions settings fixes from Jay did the trick for me!

[JohnWoo]

Thanks Amiralin, this method worked for me. Thanks!

Dear Dropbox Team, can you release a fix to solve this issue systemtically?

[johnneet]

Followed instructions, was unable to make changes to "files & folders".  DropBox label in faded mode. Locked and unlocked several times, rebooted several times, unable to make changes. Remains in fade mode. No issues with changing privacy and accessibility access.  I rebooted computer and DropBox loaded and synced with no error message.  Retried to make changes in "files and folders" with same lack of result. Test loaded files, seemed to be able to do so on about ten files I checked, but it seems that the loading was a bit slower than before. Dropbox seems to work ok at this point without being able to change the permissions on "files & folders" (remains unchecked). 

Security concern that DropBox is able to access files and folders WITHOUT permission. Am I missing something here?

[johnneet]

I think I answered my own question.

Solution 1-I was only able to change the settings in "files and folders" if I unchecked permissions for "full disc access". Changed order pf instructions and changed settings in "files and folders" first after unchecking "full disc access". My assumption is that if you give permission for "full disc access" that probably gives permission for "files and folders" as well, so he additional instruction may be superfluous.

Solution 2-On a Mac forum, the instructions are to give permission for "full disc access" and "files and folders" and "accessibility" are not mentioned in the instructions. Tried it and it worked as well.

This worked for me as well. Not sure why since it had been working fine for a day or so on this new mac.  Either way...this helped.  Thank you.

Hello everyone! 

I have the same problem on my Mac. Someone can help me (in Italian would be better).

I already followed the different suggestions, but no one worked for me.

Concerning "permissions" I do not have the possibility to click on the Dropbox icon for accessibility and disco.

What can I do?

[Steve C.13]

THIS WAS THE SOLUTION!  thanks.

after Monterey upgrade, accessibility was still check for dropbox, but NOT full disk access.

[Mhymus]

Thank you - that worked.

If your settings are greyed out then try clicking on the lock icon at the bottom try clicking on it to unlock and enter your password. It will give you the option to enable it. The you can Enable the options provided in the solution.

For me this worked like a charm, thanks a lot!!
