The project is Open Source. https://github.com/appcelerator/titanium_mobile. The prebuilt GA release is available only as part of the Appcelerator Platform. But you can live on the edge and build it yourself

2. Open Source
The project is Open Source. https://github.com/appcelerator/
titanium_mobile
The prebuilt GA release is available only as part of the Appcelerator
Platform. The Appcelerator Platform GA builds are hidden but the link
construct is as it always has been e.g. http://builds.appcelerator.com/
mobile-releases/5.5.1/mobilesdk-5.5.1.GA-osx.zip
Nevertheless it would be a step toward freedom from Appcelerator
licencing and the platform to be able to build it outselves from the
Open Source on Github.
Unfotunately the tools required are arcane and out of date.

3. Prerequisites
Apps SDK
MacOS sierra 10.12.x
Python setuptools, and the pyyaml
and Pygments libraries
Xcode 8.2.1 Android NDK r9d (obsolete)
Android SDK 23
SCons, Apache Ant, Eclipse, ADT
(for Android), Gperf
Node.js 4.2.6 max (obsolete)
Apple Java JDK for macOS 1.6
(obsolete)

4. Android SDK
To install Android Studio on your Mac, proceed
as follows:
Launch the Android Studio DMG file.
Drag and drop Android Studio into the
Applications folder, then launch Android Studio.
Select whether you want to import previous
Android Studio settings, then click OK.
Complete the Android Studio Setup Wizard
Choose Configure --> SDK manager and install
API 23 (Marshmallow / 6.0) and r21 versions of
the tools
Note SDK location /Users/angusf/Library/
Android/sdk
https://en.wikipedia.org/wiki/Android_Studio

5. Android NDK
r9d macOS 64 bit
This is no longer easy to find
but can be installed Install by
unpacking to a suitable place
fromthe old ddownload archive
https://dl.google.com/android/
ndk/android-ndk-r9d-darwin-
x86_64.tar.bz2
I chose ~/Library/Android/ndk/
android-ndk-r9d near to where
Android Studio put the SDK.

6. Brew Package Manager
Brew is s package manager for
macOS that makes it easier to
install stuff
https://brew.sh/
Ant - a Java library and command-
line tool that helps building software.
SCons used to be used to build the
Titanium SDK, it is a build tool like
make
$ brew install ant
$ brew install scons
https://en.wikipedia.org/wiki/Homebrew_(package_management_software)

7. Node.JS 4.2.6
N - Node Version Manager because
Titanium requires a very specific version of
Node.JS
$ cd /usr/local
…
$ brew install n
$ n 4.2.6
install : node-v4.2.6
mkdir : /usr/local/n/versions/node/4.2.6
fetch : https://nodejs.org/dist/v4.2.6/
node-v4.2.6-darwin-x64.tar.gz

8. • Building Titanium Mobile requires Java 1.6 Developer Tools. Java was
provided by Apple under licence from Sun Microsystems back in the
1.6 era.
• You can still find Java 1.6 for OS X https://support.apple.com/en-gb/
HT202912.
• This isn't a JDK but the note gives a clue. It says “This package
installs the same version of Java 6 included in Java for OS X
2013-005.”
• Unbelievably this installs fine on macOS Sierra. Its completely
obsolete but required for Android development.
JDK 1.6 for macOS Sierra

11. Checking what we got
This is the self built SDK.
$ ~/Library/Application Support/Titanium/
mobilesdk/osx/5.5.1
$ find . -type f | wc -l
8242
This is the 5.5.1.GA build from
Appcelerator.
$ ~/Library/Application Support/Titanium/
mobilesdk/osx/5.5.1.GA$ find . -type f | wc -
l
8242
The same number of files is a good sign.

12. Building Titanium CLI, and
Alloy
$ npm install -g titanium alloy appcelerator
$ ti sdk

13. Test
Test by creating an empty Alloy app using CLI and Atom. Open a
new terminal and enter
ti create --id com.test -d . -n APPNAME -p all -
t app -u http://youdomain.name
$ cd APPNAME/
$ alloy new
$ ti build -p ios -C ?
Hello World app should open on your simulator
