The 0.1 version of PythonTurtlefor Mac is available as a free download on our website. The program relates to Developer Tools. Our built-in antivirus checked this Mac download and rated it as 100% safe. This free software for Mac OS X is an intellectual property of Ram Rachum. The Python for Mac OS X installers downloaded from this website dynamically link at runtime to Tcl/Tk Mac OS X frameworks. The Tcl/Tk major version is determined when the installer is created and cannot be overridden. The Python 64-bit/32-bit Mac OS X installers for Python 3.4.x, 3.3.x, 3.2.x, and 2.7.x dynamically link to Tcl/Tk 8.5 frameworks.
If you're using Mac OS (OpenSesame 3.3.5 build 1) and experience an error related to freetype, download the latest Mac OS package (3.3.5 build 2).
Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package. Attempting to communicate with Arduino serial ports using Python 2.7. Have downloaded pyserial 2.7 (unzipped and put folder pyserial folder in python application folder).

.zip
packages are identical, except for the installation.The Megapack is identical to the standard Python 3.7 download above, except that it comes with a large number of libraries for scientific computing pre-installed.
Some Python packages are not compatible with Python 3. If you want to use those, please download the Python 2.7 (64 bit) package below. Note: As of January 1, 2020, Python 2.7 is no longer maintained.

Tips
Which version of Python to use?
OpenSesame is currently built with Python 3.7.6 (standard package) and Python 2.7.15.
When (not) to update?
- Update while developing and testing your experiment; it is always best to use the latest version of OpenSesame.
- Do not update while running an experiment; that is, do not update while you are collecting data.
- Run an experiment with the same version of OpenSesame that you used for developing and testing.
Manually upgrading packages
- OpenSesame is a regular Python environment, and you can upgrade packages with
pip
orconda
as described here:
Tips for system administrators
- When a new major version of OpenSesame is released (with a version ending in 0, e.g. 3.1.0), it is generally followed quickly by one or two maintenance releases (e.g. 3.1.1 and 3.1.2) that address major bugs. Therefore, if you are installing OpenSesame on systems that you do not update often, it is best to wait until the second or third maintenance release (e.g. 3.0.2, 3.1.3, etc.). That way you minimize the risk of rolling out a version of OpenSesame that contains major bugs.
- The Windows installer allows you to silently install OpenSesame using the
/S
flag.
