Many of the versions listed in this user tip are updaters, not upgraders.
Software update, upgrade--what's the difference? - http://support.apple.com/kb/HT1444
Update: These instructions are over a year old, though they may still work for you. See the “Install Python” page for the most recent instructions. A bit ago a friend and I both had fresh Mac OS X Lion installs so I helped him set up his computers with a scientific Python setup and did mine at the same time. Generally, when you insert in the USB pen drive, it will be mounted in Disk Utility and on Desktop for data access. However, a very distressing situation, just as the user above, is that the USB flash drive may not be readable, recognized, working, or not showing up on Mac. How to fix unreadable USB flash drive on Mac?
So, if you’re somebody that offers with some bootable pen drives, then do give YUMI Software on Mac an attempt. It’s going to make your life loads simpler. For older variations of this system are probably not to charge when utilizing the brand new OS. The Wacom Customer Care and Technical Support Center is full of resources and video tutorials to help you get the most out of our Wacom tablet.

Reference releases; update vs. upgrade
Recent system versions will only install the components necessary to take it to a later version of the same system and do not contain a complete operating system in the package.
Apple no longer offers this operating system except to those whose Mac came with it.
For the systems with this comment the system is still available to anybody who downloaded ('purchased' for free) it when it was still available, not just people who had it as the base system for a new computer.

These instructions detail how I install the scientific Python stack on my Mac. You can always check the Install Python page for other installation options.
I’m running the latest OS X Mountain Lion (10.8) but I think these instructions should work back to Snow Leopard (10.6). These instructions differ from my previous set primarily in that I now use Homebrew to install NumPy, SciPy, and matplotlib. I do this because Homebrew makes it easier to compile these with non-standard options that work around an issue with SciPy on OS X.
I’ll show how I install Python and the basic scientific Python stack:
If you need other libraries they can most likely be installed via pip and any dependencies can probably be installed via Homebrew.

The first order of business is to install the Apple command line tools. These include important things like development headers,
gcc
, and git
. Head over to developer.apple.com/downloads, register for a free account, and download (then install) the latest “Command Line Tools for Xcode” for your version of OS X.If you’ve already installed Xcode on Lion or Mountain Lion then you can install the command line tools from the preferences. If you’ve installed Xcode on Snow Leopard then you already have the command line tools.
Homebrew is my favorite package manager for OS X. It builds packages from source, intelligently re-uses libraries that are already part of OS X, and encourages best practices like installing Python packages with pip.
To install Homebrew paste the following in a terminal:
The
brew
command and any executables it installs will go in the directory /usr/bin/local
so you want to make sure that goes at the front of your system’s PATH
. As long as you’re at it, you can also add the directory where Python scripts get installed. Add the following line to your .profile
, .bash_profile
, or .bashrc
file:At this point you should close your terminal and open a new one so that this
PATH
setting is in effect for the rest of the installation.Now you can use
brew
to install Python:![Pen Pen](https://cdn.servicetarget.com/site-resource%2Fwacom%2FIOmanaer.IxXF79.jpg)
Afterwards you should be able to run the commands
and see
for each, respectively. (It’s also possible to install Python 3 using Homebrew:
brew install python3
.)It is possible to use
pip
to install NumPy, but I use a Homebrew recipe so I avoid some problems with SciPy. The recipe isn’t included in stock Homebrew though, it requires “tapping” two other sources of Homebrew formula:You can learn more about these at their respective repositories:
With those repos tapped you can almost install NumPy, but first you’ll have
to use
to use
pip
to install nose:I compile NumPy against OpenBLAS to avoid a SciPy issue. Compiling OpenBLAS requires gfortran, which you can get via Homebrew:
And then you’re ready for SciPy:

matplotlib generally installs just fine via
pip
but the custom Homebrew formula takes care of installing optional dependencies too:You’ll want Notebook support with IPython and that requires some extra dependencies, including ZeroMQ via
brew
:Pandas should install via
pip

The most basic test you can do to make sure everything worked is open up an IPython session and type in the following:

If there are no errors then you’re ready to get started! Congratulations and enjoy!
