**Not sure if this is the best place to post this question... ** Yes, I have newer Apple devices. I, in fact, bought this Macbook because i like the look of the black edition. I'm going to be upgrading it to 6 GB ram and a 500 GB SSD. I have read that Mavericks can be hacked onto the Macbook I have, but I also read there might be issues with the video graphics (resolution problems, can't change brightness, etc.) and the audio (no sound). I would stay on Lion but I want to use some software that only works on Mavericks and later OSs. Have any of you done this successfully without compromises?
