I have the latest update from MavensMate and I'm unable to see intellisense, how to turn on that feature?

To enable that, I would recommend you consider adding some more sublime plugins. Consider the following two: https://packagecontrol.io/packages/haoide and https://packagecontrol.io/packages/Visualforce
