Permissions Error

Permissions Error

Everytime I reboot I get the error about dropbox not being able to start due to a permissions problem. I've tried the trick outlibne here about holding down the option key but I suspect that was for an either version.  Here's the text:

Hi @stryder,

Seems the application experience some difficulties accessing cache files/folders. Try wipe them up, using following command in terminal (copy/paste it as is):

rm -rf ~/Dropbox/.dropbox*

Hope this helps.

Thanks for the attempt but it did not work.  Deleted .dropbox.cache and .dropbox with that command but upon reboot, the error message still comes up.

🤔 Hmm... Strange! Maybe there are some other restrictions set. Can you try do by hand exactly the same what Dropbox application tries to (and fails to), using following:

xattr -w com.dropbox.ignored 1 /Users/don/Dropbox/.dropbox.cache

Is the above command passing without error?

Thanks for your help.  I looked at my history and see that I mistyped the rm command  (rd did not return an error, go figure). I am betting that your original solution would have worked.  What I did find though was not an OS permission problem.  Rather, I use Bitdefender for AV.  They have a ransomware protection feature where an app needs to be whitelisted. I never whitelisted Dropbox.

Can someone help me please.  I've  been using Dropbox for over 10 years.  Today I logged on and got:

 

"Couldn't start Dropbox.  This is usually because of a permissions error.  Storing you home folder on a network share can also cause an error."

 

Dropbox is not in my task bar and nothing is hidden.

 

Many thanks 🙂

Hi @AnnieSuzie,

Didn't the workaround, provided here, work for you? 🤔 If not, is your error the same (not just the title, but the entire text too)?

If you can't figure out the real state, post the entire log, so someone could be able help you.
