I bought a 2.6/8/256 late 2013 13" MBPr. I know it can turbo boost to 3.1 GHz, but is there any way to know when it is turbo boosting? Also, what do I have to do so that it would turbo boost? Like what apps would make it turbo boost? Last question, can I leave turbo boost on all the time? It'd be cool to run my machine at 3.1 GHz.
