This program 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.

Install mine with pipx (or pip):

$ pipx install mine

or directly from the source code:

$ git clone https://github.com/jacebrowning/mine.git
$ cd mine
$ python setup.py install


Create a mine.yml in your Dropbox:

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

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.


To synchronize the current computer's state:

$ mine

To close applications on remote computers and start them locally:

$ mine switch

To close applications running locally:

$ mine close

To close applications locally and start them on another computer:

$ mine switch <name>

To delete conflicted files in your Dropbox:

$ mine clean
