## How can I use TKinter with Python 3 in macOS 10.8?

Using TKinter with Python requires X11. It is not included in macOS 10.8 and later. To install it, download Xquartz.

## How can I configure or opt out of the Intel Math Kernel Library (MKL)?

For information on configuring and uninstalling MKL, see the Anaconda MKL documentation.

## How can I use Anaconda on macOS 10.5, 10.6, 10.7 or 10.8?

The command line installers for Anaconda versions 1.8 and earlier support macOS 10.5 and macOS 10.6. These installer files end in `.sh`, not `.pkg`. Anaconda versions 4.2 and earlier support macOS 10.7 and macOS 10.8. Download them from our archive.

## How do I get the latest Anaconda with Python 3.5?

We recommend downloading the latest version of Anaconda and making a Python 3.5 environment.

A second option is to download the latest version of Anaconda and then run this command to install Python 3.5 in the root environment: `conda install python=3.5`

A third option is to download the most recent Anaconda Installer that had Python 3.5 by default. This is Anaconda 4.2.0. You can download it from our archive. Scroll down the page until you find version 4.2.0 for your platform.

## Should I add Anaconda to the Windows PATH?

We recommend not adding Anaconda to the Windows PATH, since this can interfere with other software. Instead, use Anaconda software by opening Anaconda Navigator or the Anaconda Command Prompt from the Start Menu.

## How can I use Cython on macOS?

Cython needs a C compiler, so you need to install Xcode.

## How can I use Theano?

Theano requires gcc for acceleration.

To install Theano with acceleration:

- On Windows, run `conda install theano`.
- On Linux and macOS run `conda install gcc theano`.

NOTE: As shown in the package list, Theano is not installed with Anaconda by default, but Theano is available from the default Anaconda channels for Windows, macOS and Linux.

## How is CPython compiled?

- Python 2.6 and 2.7 were compiled with Visual Studio 2008.
- Python 3.3 and 3.4 were compiled with VS 2010.
- Python 3.5 was compiled with VS 2015.
