I was successful installing Sierra, everything working fine, audio net, graphics, etc.
My problem is that almost every time i reboot i get the prohibited sign, most of the times it comes 2 times in a row and then the third time i am able to login. weird right?
Any ideas?

Assuming you're not using slide=0 already...
Add 'slide=0' kernel flag to config.plist/Boot/Arguments

Also check that you're using config.plist/RtVariables/CsrActiveConfig=0x67

No, not really, I just deal with it, sometimes rebooting 3 times, I try to avoid restart it as much as possible. I'm surprise with all the experts here no one has suggested anything, for now we just have to wait.

I have the same problem and asked for help in another post saterday. This evening, as suggested by RehabMan at post # 4, I entered in config.plist slide = 0 and verified to be csractiveConfig = 0x67 but the problem persists. What else suggestion?
 
RehabMan Can you also check my post here. I have a similar problem and I have my verbose messages.

No "Problem Reporting" files there either...
But I would recommend OsxAptioFixDrv-64.efi instead of OsxAptioFix2Drv-64.efi in addition to the items in post #4.
