General installation of ROOT on a Mac

I am not extremely technical w/ computers, but I need to install ROOT on my Mac. Which binary distribution for Mac is the best to download, and once I have downloaded the tarball and unpacked it on my computer, what steps do I take from there to set it up and run it?

I have not found the instructions online very helpful.

Also, if I’m interested in using PyROOT, how is this installation process different?

It’s also worth noting that I am running OsX Yosemite 10.10.5

root.cern.ch/downloading-root , pro version. Osx releases come with dmg packages. Clicking on the file once downloaded installa (like all dmg packages).

root.cern.ch/getting-started

Feel free to suggest any improvement.

PyROOT is part of ROOT.
