Multibeast failing to install (worked before) EFI mounter failing to mount.

Hello Hackintosh family, I found myself in a slightly annoying pickle...
My rig is as follows
CPU - Intel i7 2600k Sandybridge
Mobo - Asrock z68 Extreme7 Gen3
RAM - Corsair 16gb 4gb=1 Stick
GPU - Nvidia EVGA GTX 980ti SC
Mac os - Sierra 10.12.4

I used multibeast and installed everything perfectly the first time and many other times after that however, when I try to use MB now it fails and says to check the log file ( which I cannot find for the life of me, I searched everywhere on the HDD )
The reason as to why I would want to use MB after installing everything (or mostly everything) is because I have terrible performance in Final Cut Pro, only during playback of my project (when one clip changes to another there is lag/fps drops) after some researching I found that if I change my SMBIOS to mac pro 5,1 I should see an increase to performance. The only other installation failure I've ever encountered was with kaspersky (after Sierra installation) so I installed Norton and it worked.

Yesterday I tried installing my onboard audio drivers and it failed but managed to install them a different way.
I'll also mention that EFI Mounter V3 doesn't mount and throws and error as well as V2. They worked previously as well. Not sure what I broke and why all of these amazing gifts from developers no longer seem to run on my Hack.
I found a terminal work around for EFI mounter but I don't feel savy enough to modify SMBIOS using terminal/finder
Please if anyone could assist me with this issue I would really appreciate it. Thank you

EDIT: I got the SMBIOS to install through Multibeast after manually mounting EFI. I guess the error was because of that but I'm curious as to why this is happening and will not automatically mount the EFI partition. As well in "about this mac" section it still reads as an iMac 27" 2011 Model
