Messed up my system (Please Help)

I recently reinstalled Yosemite to revert back to Chimera instead of Clover (iMessage didn't work anyways). Everything was up and running fine, Bluetooth and WiFi mainly, OOB. However, to get sound and all my kexts installed I ran MultiBeast using the following settings for my ga-z87m-d3h motherboard.

Sound and all works great but when and only when I have my USB 3.0 external HDD plugged in during boot it freezes with - in the top left instead of \ | / or anything else, the bar does not spin. Please help as this is annoying to unplug the external HDD everytime I want to restart the computer. I removed the Generic USB kext thinking that may fix it since I read on the MultiBeast PDF that is what the Universal 3.0 USB kext installed.

Thank you for reply. I will try this once I get back from Thanksgiving.

Okay. Sorry about the long delay I just wanted to make sure I tried everything before posting.

I did a completely clean install of Yosemite on my computer and it booted fine the first time. I then ran Multibeast and installed all my drivers besides the USB 3.0. After it completed, I restarted and the computer will not boot. After this happened again after trying the new steps I took apart the external drive and placed it inside the computer. Thinking this would solve my issue since it was no longer USB at all I started the computer. Again it stopped at the same exact place as before and I cannot set it up to boot with -v.

TLDR - clean install of Yosemite, Multibeast setup WITHOUT USB 3.0 driver = Not Working Removed hard drive from enclosure and made internal = Not Working

The drive is Hitachi 2TB taken from a Toshiba external enclosure. Please help as I am forced to run Windows 8.1 right now and would really love the Hack back.

Read through this post, they have issues with USB as well:

I read through the post; however, I do not believe my issue is with USB 3.0. As stated in previous post, I took the hard drive and made it internal connected directly with SATA.

Is it possible that Hitachi drives are not compatible with hackintosh?

USB (USB3 in particular) is notoriously hard to fix in OS X when you have a problem with it. I would recommend patching it yourself if you can, as it requires kexts + DSDT patches + other things.. See here:

Would patching the kexts fix my problem of not booting? I have no usb plugged in besides my keyboard and mouse. The computer boots fine if the Hitachi drive is not plugged in but once it is plugged in it will not boot.

By plugged in i mean to SATA......I have NO USB HDD.

I am going to read the insanelymac posts but do not believe this is my issue. I will gladly admit if I am mistaken and this fixes it.

New question: is it possible that since I only have 1 stick of 8GB ram that it would mess with my system? Also, with my Radeon HD6850 connected I cannot get the installer to run, it hangs on the beachball before installation starts. After removing the video card and using the built in intel hd4600 the system booted fine, ALTHOUGH I also went into BIOS and loaded default and then turned off VT-d and set memory to Profile 1. Upon booting the system froze.

It works fine under Windows but this is a totally different beast. Also, I installed Yosemite directly onto the Hitachi drive I thought was not compatible. I get some kernel panics and will try to capture those tonight if it keeps happening. With school going on this is a slow WIP. Will keep undated and I am noting all my progress so I can possibly post a guide on how I did it.

Update: System still will not boot unless I use USB thumbdrive with unibeast on it and use -v boot option.

I wonder if doing Mavericks would work? Anyone still using Mavericks as OS?

Also, I just noticed and this may be my problem all along. Does the HDD have to be formatted into Master Boot Record or can it be GUID? I remember this last time using GUID.

I have the same MB and fixed the USB3 freeze problem by having my USB2 keyboard and mouse connected to a USB3 outlet on the MB (shown as USB Receiver). I can now connect and disconnect USB drives without any problems. Note the ADATA drive is connected to a USB 3 connector.



I fixed the black screen on boot problem by disabling on board video in BIOS and used the following MultiBeast 7.1.1 settings



Note, I am using an iMac 14.1 definition.

Added: My SSD is formatted GUID
