CyanogenMod 13 is slowly unofficially rolling out to many devices. Motorola has been pretty quick at releasing updates for their newer devices. Some of the older devices seem to be placed on the back burner. This is where the mod community really comes in handy! We already have a build of Marshmallow Android 6.0 for the Moto X 2014 thanks to CyanogenMod. The CM13 build for the Moto X 2014 is unofficial and their will be some bugs. You will need to be bootloader unlocked with a custom recovery installed to get CM13 on your device. Head to the link below to grab the files needed.
