These tricks have been tested on a Mac OS X so far (including Snow Leopard), with version 0.6.570 of Dropbox. These tricks do not appear to produce a working alternative Dropbox instance app in Mac OS 10.7 (Lion). Try DropboxEncore instead, which works with Lion.

General idea

The basic idea is to just start Dropbox from the command-line using an alternate home-dir. This will create another Dropbox icon, and another Dropbox folder, which has to be in some other place from the original one. One way to distinguish the two menu bar icons is to change one to Leopard style (black and white) in its Preferences. The two Dropbox folders will both be called Dropbox (this cannot be changed), but you can distinguish them by their location, precisely. Each instance can be used with a different Dropbox account. For instance, I have a personal Dropbox account and one for professional use. On my laptop, there are separated on two different user accounts, but at home, I would like both on the same user account. Hence, at home, I use the trick below. Technically speaking, this trick could be made an unlimited number of times.

On Mac OS X

Set Up

Launch /Applications/Utilities/Terminal.app. Make sure you are running a “bash” shell. If needed, just type:

bash

Then paste the following command:

HOME=$HOME/.dropbox-alt /Applications/Dropbox.app/Contents/MacOS/Dropbox &

Now, you should entering a new Dropbox setup wizard window. A second Dropbox icon should appear on the status bar. Choose an existing account if you have one (different from the original one!) or create a new one. Make sure you choose an alternate location for your new Dropbox folder. If you quit the terminal, the new alternate Dropbox process will also quit. But do not worry! It is set up, and the remaining part of the trick below explains how to restart it with a dedicated little app bundle.

Start automatically on login

There are two methods for this. One method is to create a small app bundle that you then add to startup items. Alternatively, you can use Automator to create an application that runs the bash command above in Terminal.

Automator Method

  1. Open Automator from your Applications folder
  2. Choose the ‘Application’ template from the template chooser
  3. In the Actions Pane on the right side, Choose ‘Library > Utilities’
  4. From the next pane choose ‘Run Shell Script’ and drag it into your workflow.
  5. In the Run Shell Script text box, paste the command you used above:
    bash HOME=$HOME/.dropbox-alt /Applications/Dropbox.app/Contents/MacOS/Dropbox &
  6. Make sure to include the linebreak.
  7. Run the script (button on the top right) to make sure it works.
  8. Go to File > Save As and save anywhere.
  9. Add the resulting application to your Login items.

App Bundle Method

In order to run the second instance automatically on login, you’ll have to create a small app bundle, which you will later add to startup items in the System Preferences “Accounts” pane. Starts by pasting the following command into Terminal. Again, do not include the initial dollar sign of each block:

mkdir -p ~/<whaveter place you like>/DropboxAltStarter.app/Contents/MacOS/

This will create recursively, if they do not exist, the folders “DropboxAltStarter.app”, “Contents” and “MacOS”. If you change the name “DropboxAltStarter” for something else, make sure you change it everywhere relevant in the next lines.

Now, open a text editor, and paste the following code:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict>     <key>CFBundlePackageType</key>     <string>APPL</string>     <key>CFBundleExecutable</key>     <string>DropboxAltStarter</string>     <key>LSUIElement</key>     <string>1</string> </dict> </plist>

And save it with the name “Info.plist” (this is crucial, do not choose another name) and save the file inside “DropboxAltStarter.app/Contents”! Now, open a new text file in the text editor, and paste the following text (warning: make sure you remove the leading whitespaces – I had to put one because of wiki formatting):

#!/bin/bash  HOME=/Users/$USER/.dropbox-alt /Applications/Dropbox.app/Contents/MacOS/Dropbox

and save it with the same name as specified in the Info.plist file (i.e. look at the string just below “<key>CFBundleExecutable</key>”). And save the file inside “DropboxAltStarter.app/Contents/MacOS”! (Yes, with “MacOS” this time). You can close your text editor.

Make sure that your script is executable, by typing the following command in a terminal:

chmod 755 ~/<whatever place you like>/DropboxAltStarter.app/Contents/MacOS/DropboxAltStarter

Now, in the “<whaveter place you like>” directory, you have a small Mas OS X app bundle. You can add it to your login items in the System Preferences->Accounts. You can also double-click on it everytime you need to start this second instance of Dropbox (i.e. if it crashed).

On Ubuntu

Note: It doesn’t seem to work with version of 0.7.110 on Ubuntu 9.10

Set Up

Open a terminal or whatever shell. Then paste the following commands:

mkdir $HOME/.dropbox-alt HOME=$HOME/.dropbox-alt /usr/bin/dropbox start -i

Now, you should entering a new Dropbox setup wizard window. A second Dropbox icon should appear on the status bar. Choose an existing account if you have one (different from the original one!) or create a new one. Make sure you choose an alternate location for your new Dropbox folder. If you quit the terminal, the new alternate Dropbox process will also quit. But do not worry! It is set up, and the remaining part of the trick below explains how to restart it with a dedicated script.

Start automatically at boot

For Most Scenarios

edit /etc/rc.local as root (Mac OS X uses /etc/rc.common), then add the following line:

su <user> -c "/home/<user>/.dropbox-alt/.dropbox-dist/dropboxd &"

Where <user> is the username under which you want to run Dropbox.

For More Recent Versions of Linux

Disable the autostart feature of the existing Dropbox account. Then copy your existing credentials to a new folder, like so:

mv .dropbox .dropbox-personal

Create a new script called MultipleDropboxInstances.sh which contains the following:

#!/bin/bash
dropboxes=".dropbox-personal .dropbox-work"
for dropbox in $dropboxes
do
    HOME="/home/$USER"
    if ! [ -d "$HOME/$dropbox" ]
    then
        mkdir "$HOME/$dropbox" 2> /dev/null
        ln -s "$HOME/.Xauthority" "$HOME/$dropbox/" 2> /dev/null
    fi
    HOME="$HOME/$dropbox"
    /home/$USER/.dropbox-dist/dropboxd 2> /dev/null &
done

Give this file executable rights:

  $ chmod +x path/to/your/file

Now add this file to your startup programs. (Note, this can be edited to accommodate as many instances of Dropbox as you wish. Just add an entry in the line defining the directory names: dropboxes=”.dropbox-personal .dropbox-work .dropbox-whatever”.)

This can be done for as many users as you like, provided that they actually exists and that they have Dropbox installed/symlinked in their home folder. You’ll also need to set it up manually the first time, as it requires a graphical interface to link to an account. The above can also be used to auto-start Dropbox on systems which are not running Nautilus as the file manager.

    Thank You for this! It works flawlessly.
    Best,
    Sandeep.

    It almost worked! But when you say to save the new app “someplace different,” what do you mean? I saved it on my Desktop and suddenly started syncing to my OTHER (original/primary) DB account!

  • lola

    The instrux for Dropbox Encore are fantastic! Wish I’d realized that the article on this page wouldn’t work on my OS X Lion 10.7.5…but DB Encore saved the day.

    • Dropbox Wiki

      Hi @disqus_v5enetoply:disqus, I’m glad you were able to get Dropbox Encore working. We tried to make it as clear as possible at the top of the article that Dropbox Encore should be used but we’ll try to make it even more clear.

    I’m running dropbox under archlinux and the trick isn’t working that well.

    The command : «HOME=/home/miman/Dropbox-partitions/ /usr/bin/dropboxd start -i» returns

    «No protocol specified
    This client is not linked to any account…
    Please visit https://www.dropbox.com/cli_link?host_id=6641d69c1b57555836f874e0fb9ab5e5 to link this machine.»

    When I visit the link, it asks a password (which I give, of course) but… the same message is being send each time I try to connect by cli…

    Thanks for your help

    • draffin

      Ok, I finally manage to solve that little problem (you mustn’t close the processus while you follow the link…)

  • Gregory H

    While I was able to get the multi DBs set up and working the first time around, and the alt dropbox folder is available on my computer, I cannot get the automator or app bundle methods to work for opening the alt db app on startup (so i have two icons in my status bar and can change db settings in the alt db).

    With the automator method: if i have a line break (so that & is on line 2) i get an error that the $HOME/.dropbox-alt doesn’t exist (even though it does). When i remove the line break, this does seem to work when i test run it, but when i run the new app, i don’t get the icon in my tray.

    With the app bundle method, the app seems to run, but the tray icon doesn’t appear.

  • jake

    is this still working on the latest dropbox release on linux?

    • Fabian

      It works with version 2.4.6 (Ubuntu 13.04)

  • diasse

    This is just awsome! Works great in OS X 10.9 and thnx for a great tutorial! :-)

  • olgv

    DB Encore not working after updating to 10.9.2, any suggestions ?

    • olgv

      also, while using the “Automator Method” for starting automatically on login.. the DB instance starts but the automator workflow doesn’t stop… I get the automator workflow’s spinning crank wheel.. going on and on … and on :( , until I kill the workflow manually, though the BD instance remains on

  • studid is as stupid does

    I did this successfully on my macbook (using these instructions: http://theterran.com/blog/2012/6/14/use-two-dropbox-accounts-on-one-computer.html) which, several months later I spilled soda on :(

    Is there a way to access the shell script (not the original) dropbox account from another computer/via dropbox online or is my only option to get the files extracted off my (non-functioning) laptop ($$$)?

    Thoughts and suggestions much appreciated!!!

    Does this include being able to set up a new Dropbox account by accepting a referral from my personal account to my new business account?
    Edit: OS X 10.9.3
