    hi guys, I need your help. Yesterday after backing up to TimeCapsule I've started the installation of the Sierra. Problem after everything went smoothly, in the last - or I think it's the last one - reinitialization it just froze almost at the end. After 6 hours waiting to see if something would happen, I just hit the power button and restarted it... but it frozen in the same spot... how can I solve this?
    It's a MBP from mid 2012 with 16gb of ram and a 1tb ssd. Thanks

    If it's stuck in a loop – repeatedly trying, failing to install – then a reset of NVRAM may break that loop enough for you to get a Recovery OS view of things.
