Q: mac sierra startup progress hanging needs help

Have a mid 2012 15 inch macbook pro retina

Updated to mac os sierra last week

Then i started having startup progess issues initially i w2as able to startup using command r recovery tool

But after 2 shutdowns it started happening again  this time not even recovery  safe mode or resetting nvram works

I use startup verbose mode and attached pictures where the verbose txt hangs maybe thiz would help
