Hi, I've just installed the new update on my macbook, however I am now unable to boot up. The problem is that when I turn on the mac, during the boot screen with the apple logo and progress bar, the progress bar will get to around 50-70% and then shut off. I've had my macbook for two days now and am relatively new to using OSx. The machine is just plain shutting down during any kind of boot. The apple shows up and in the middle of the progress bar it just turns off. Recovery mode shuts down. Internet Recovery mode it.
