Q: El capitan upgrade stops boot up sequence

Immediately after an el capitan safari update (21/9/2016), my 2011 mbp shut off abruptly. Now, when I power on, it sticks after I enter my password. I've tried this several times, no success. Internet Recovery failed at the point of waiting to see the utility screen. Command + R or shift when powering on does not work either. What should I do?

Can you help?

MacBook Pro (17-inch Late 2011), iOS 10, null

Try booting into Safe mode
<http://support.apple.com/kb/ht1564>

Also try resetting the SMC and PRAM
<Reset the System Management Controller (SMC) on your Mac - Apple Support>

If you can get booted into Safe mode, please post the output from EtreCheck

Hi BobHarris

Thanks for your input. Sadly, safe mode is not working and I cannot get to do the resets you recommended.
Not sure what else to do. I'll have to contact apple

Thanks again

I do not understand why you cannot reset the SMC and NVRAM? They do not require software, just holding various keys while powering up?

It sounds like it is time to make a Genius Bar appointment at your local Apple store.

When I try resetting the NVRAM, i.e., holding down the cmnd + P +R buttons, the page just stays white for very long. Nothing else happens. Keep in mind, that the original problem began with the computer shutting off abruptly.
