I just got a new macbook and is now installing apps to it. After setting up Dropbox and everything else, I decided that I wanted to change the account name (which was previously "mac") to my name. Everything worked fine, until I tried to open Dropbox, it asked for permission to the wrong user folder (of the old account name) like this:

I tried unlink my computer from Dropbox account and reinstalling Dropbox, the software keeps looking for that folder's permission. What should I do to fix this? Please suggest and thanks.


After I type my login details, this is what I got:

enter image description here

The thing is the folder /Users/mac doesn't exist. I click on the link of the dialog and got this log:

Please note the lines I've emphasized with bold text: the wrong path to Dropbox was given. It should be /Users/ichigo instead

    I ran into this exact same issue with one of my users two days ago. Unlinking Dropbox, completely removing Dropbox (from /Library & ~/Library preferences, caches, etc) and reinstalling Dropbox had no effect. So far Dropbox support hasn't responded to our help ticket. If they do I'll pass along the info, otherwise I'll be watching this question and would like to add a bounty to it once it's eligible. – Mr Rabbit Apr 24 '14 at 13:07

    This was helpful for getting around the Dropbox issue. However, I found that so many applications had hard-coded the username that the best way forward was to create a new user with the desired username and start over. – jwhitlock Jul 10 '15 at 14:25

Funny timing, just received this back from Dropbox support and it seems to have resolved my user's problem. Her issue similarly popped up when we migrated her to a new Mac and then changed her user account name.

Thanks for writing in. If you're having trouble running Dropbox on your Mac then please try these steps and then restart Dropbox.

1. Stop Dropbox (If needed):

  • Click the Dropbox icon in the menu bar at the top of your screen
  • Click on the gear icon in the Notifications panel and select 'Quit Dropbox'

2. Download the newest version: www.dropbox.com/install

3. Open your Terminal app (Located at /Applications/Utilities/Terminal)

4. Copy and paste the following lines into the Terminal, ONE AT A TIME, and press ENTER after each one. PLEASE make sure you copy and paste these commands (don't type them by hand), as getting them wrong could cause some harm. You'll be prompted for your computer's admin password (not your Dropbox password) after entering the first command. Keep in mind that the password field in the terminal will remain blank as you type your password. After you type it, just press ENTER.

sudo chown "$USER" "$HOME"

sudo chown -R "$USER" ~/Dropbox

sudo chmod -R u+rw ~/Dropbox

sudo mv ~/.dropbox ~/.Trash/dropbox.old

sudo mv ~/.dropbox-master ~/.Trash/dropbox-master.old

sudo chmod -N ~

sudo mv /Library/DropboxHelperTools ~/DropboxHelperTools.old

5. Open the .dmg file from step # 2 and double click the Dropbox icon to install Dropbox.

6. Restart Dropbox from the Applications folder.

Hopefully that does the trick for you as well!

    Really nice timing haha! This totally solves the problem, thanks so much for your time. – huong Apr 24 '14 at 15:49

    In my case, all I needed was mv ~/.dropbox ~/.Trash and sudo mv /Library/DropboxHelperTools ~/.Trash. – Andrew Nov 10 '14 at 16:39

    If you wanted to remove them, then why not simply rm -rf ~/.dropbox? – Bert Visscher Nov 1 '16 at 9:00

Uninstall and re-install:

rm -rf ~/.dropbox/ && rm -rf /Library/DropboxHelperTools

Then run the installer again.

  • Better than the Dropbox-provided answer. Except that it should use sudo as follows: sudo rm -rf ~/.dropbox/ && sudo rm -rf /Library/DropboxHelperTools – rinogo Jul 25 '18 at 18:12
