This is a program that lets you synchronize application data using Dropbox.

It automatically starts and stops programs that would otherwise fight over data in a shared folder and ensures only one instance is running. Many applications work fine when their data is stored in Dropbox, but some programs overwrite databases:

  • iTunes
  • iPhoto
  • etc.

while others periodically write snapshot data:

  • Eclipse
  • Xcode
  • etc.

and some just don’t make sense to keep running on all your computers:

  • Slack
  • HipChat
  • etc.

Getting Started


  • Python 3.3+


mine can be installed with pip:

$ pip3 install mine

or directly from the source code:

$ git clone
$ cd mine
$ python3 install


Create a mine.yml in your Dropbox:

  - name: iTunes
      auto_queue: false
      single_instance: true
      linux: null
      windows: iTunes.exe
  - name: Slack
      auto_queue: true
      single_instance: false
      linux: null
      windows: null
  - address: 00:11:22:33:44:55
    hostname: My-iMac.local
    name: My iMac
  - address: AA:BB:CC:DD:EE:FF
    hostname: My-MacBook-Air.local
    name: My MacBook Air

Include the applications you would like mine to manage. Computers are added automatically when mine is run.

The versions dictionary identifies the name of the executable on each platform. The properties.auto_queue setting indicates mine should attempt to launch the application automatically when switching computers. The properties.single_instance setting indicates the application must be closed on other computers before another instance can start.

For remote application management, mine needs to be started automatically on each of your computers. Cron is good for this:

  1. Find the full path to mine with $ which mine
  2. Add a crontab schedule with $ crontab -e: @reboot /path/to/mine --daemon --verbose >> /tmp/mine.log 2>&1 &

Basic Usage

To synchronize the current computer’s state:

$ mine

To close applications on remote computers and start them locally:

$ mine switch

To close applications locally an start them on another computer:

$ mine switch <name>

To delete conflicted files in your Dropbox:

$ mine clean
