Hello, new here. 2010 Macbook pro (intel core 2 duo) I'm posting this because I can't quite find another thread or other person with the exact same problem as me. I was uploading pictures on gmail when for the first time ever my mac froze. I held down the power and shut it off then I turned it back on, and it booted up windows XP. I set up bootcamp to default boot into OS X snow leopard. and its been set up that way for almost a year. I thought it was weird, so I turned it off and booted again holding option and chose mac. but it booted into windows anyways. I've tried zapping the NVRAM and safe booting it. I've checked in my bootcamp settings that it is indeed set to boot into mac, and even chose it to restart into mac from the bootcamp option. No matter what I do it refuses to boot into Mac OS X, always booting into windows. Its really frustrating as I rarely use the windows partition, and all my important things are on the mac partition. Can anyone offer any suggestions or help?
