I am running Yosemite on my Macbook Pro and I have been running a Ubuntu VM in order to display my Dashing dashboard.
The VM causes my CPU and fan to go crazy so I would prefer to just use the thin client and run it directly from my Mac.
You can install it on your own Mac by doing the following, copy and paste the following in the terminal. You might have to make sure that you have xcode command line tools are installed on your Mac first.
sudo xcode-select --install
Once the install is finished for XCode, open Xcode from Applications and accept the licensing agreement. You should be able to install Dashing with no problem
sudo gem install bundler
sudo gem install dashing
Change directory to the place you want to create your new dashboard and it's files.
The next part will get you started with a cookie cutter install of Dashing.
dashing new dashboard
You can then access it via localhost. So http://localhost:3030/
I had a couple of issues when attempting to get my gems installed. I had to run the following commands to getting it working.
bundle install --path vendor/cache
