<h2h4> Python </h2h4>
The following have been tested on Mac OS X Yosemite (10.10) - earlier versions may not have a recent enough Python installation (recommended 2.7.6 or later). It's possible to install other Python versions on your Mac OS X via the 'homebrew' system, we will use this for installing a few additional required tools.
<li><p>Install the 'homebrew' system, see [http://brew.sh brew.sh] for details. Briefly, you can install it by pasting the following in a terminal:</p>
<pre>$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"</pre></li>
<li><p>As PySide is based on Qt 4, which is not officially supported by Homebrew, you will need to load the [https://github.com/cartr/homebrew-qt4 homebrew-qt4 tap]:</p>
<pre>$ brew tap cartr/qt4</pre></li>
<li><p>Install PySide using homebrew:</p>
<pre>$ brew install pyside</pre>
<p>If you recieve an error saying that no such package exists, you can also install PySide using the pip installer</p>
<pre>pip install -U PySide</pre>
<p>The install will probably print a message like this:</p>
<blockquote><p>[[File:Install_macosx_brewpath.png|image]]</p></blockquote>
$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/macmini/Library/Python/2.7/lib/python/site-packages/homebrew.pth</pre></li></ol>
<h2h4> SciPy </h2h4>
You may need to upgrade your SciPy from the base install if you wish to do template attacks. This is not needed for other attacks, so please only proceed with the following if you receive an error that your version of scipy is too old.
brew link --overwrite numpy
<h2h4> libusb </h4>libusb is needed for the ChipWhisperer software to communicate with the board. Again, use brew: brew install libusb <h4> AVR-GCC </h2h4>
You can easily use brew to install avr-gcc, as decribed at [https://github.com/osx-cross/homebrew-avr/ OSX-Cross Project]:
$ brew tap osx-cross/avr
$ brew install avr-libcgcc
