[Solved] Boot issue...

[magrosi65]

Hi all!
I've just installed Sierra 10.12.1 on my pc. (Gigabyte Z170 Gaming 5 - I7 6700 - GTX760)
The major problem, at the moment, is boot realated.
I can boot Mac OS only if I use the pen drive boot loader (removing in options the "nv_disable=1" parameter).
If I try to boot from the boot loader installed by Multibeast on the system disk, the OS load for a few seconds and then fail.
I'm a newbie, so...any help will be appreciated, thanks!

Solved changing SMBIOS settings.

Solved changing SMBIOS settings.

I am having the same issue.
What did you use to change the SMBIOS?

Thanks for your help.

I have just mounted the EFI partition, and I edited the Clover config.plist.
This is my SMBIOS section:

<key>SMBIOS</key>
<dict>
<key>ProductName</key>
<string>iMac14,2</string>
<key>Trust</key>
<false/>
</dict>

I hope it will work for you too.

I've had this happen when using the system definition 3,1, had to change to 14,2
Also had this happen when SIP was enabled, had to go to recovery and csrutil disable from terminal.
One time, it was because it was conflicting with my ML2 installation, so I had to wipe the drive.
