I will explain here how you can Root the lastest Andy OS under Mac OS X.
Preparation
First of all you need following:
For checking if Andy is rooted, you should download RootChecker .
Install ADB
(if you already have ADB, you can skip this step)
Open a Terminal an install android and android-ndk
1sudo port install android android-ndk
After successful installation you should find the android sdk under /opt/local/share/java/android-sdk-macosx, so we can launch the Android SDK Manager
1sudo /opt/local/share/java/android-sdk-macosx/tools/android
You need to install Android SDK Platform-tools and Android SDK Build-tools
After installation you should find adb under /opt/local/share/java/android-sdk-macosx/platform-tools/adb
Root Andy
We need to open a Terminal to execute adb (Andy must be running to execute the next steps). You should have extracted SuperSU, for example to /tmp/UPDATE-SuperSU-v2.46
Start installing Superuser.apk
1/opt/local/share/java/android-sdk-macosx/platform-tools/adb install /tmp/UPDATE-SuperSU-v2.46/common/Superuser.apk
Now we need to copy su to Andy (as /sdcard is readonly, we need to copy files to /data/local/tmp)
1/opt/local/share/java/android-sdk-macosx/platform-tools/adb push /tmp/UPDATE-SuperSU-v2.46/x86/su /data/local/tmp/
Next step is to replace existing su with ours
1/opt/local/share/java/android-sdk-macosx/platform-tools/adb shell
2su -c "sh"
3whoami #It should return "root"
4mount -o remount,rw /system
5mv /system/xbin/su /system/xbin/su.bak
6cp /data/local/tmp/su /system/xbin/su
7chmod 06755 /system/xbin/su
8mount -o remount,ro /system
Andy should now we rooted, you can check it using RootChecker
