Check this (update2) if the symptom is like a no signal to the monitor after apple logo:

Hi all, I want to report a problem I have with unraid 6.7.2 and the latest version of the plugin available as of today. I have 3 disks in unassigned devices and I'd want to be able to local mount 2 of them to be able to share them in my vm. Both disks are western digital, one of 2TB (sdc), the second one of 6TB (sde), both are ntfs. I have no problem with the 2TB disk, I can mount and share. In unraid webGui the mount button is greyed out for the 6TB disk, so I cannot mount it through the plugin. What I did: Through firefox "inspect element" I tried to force the button to be active, by deleting in the html code disabled="": the button is now enabled, by clicking the mount button the disk is not mounted (obviously), but i have one more row in the log file: no filesystem detected. In fact, in the fs column in the webGUI there's no ntfs for this disk. The disk seems to be ok, it can be accessible in windows 10, no errors when checked. Strange thing is that it is mounted through unraid if i mount the disk in the terminal with this command (mount the disk after creating the folder in /mnt/disks): mkdir /mnt/disks/6TB /sbin/mount -t ntfs -o auto,async,noatime,nodiratime,nodev,nosuid,umask=000 '/dev/sde1' '/mnt/disks/6TB' The disk is mounted and through the webGUI I can share it (however the fs column for this disk remains empty). I can also unmount the disk through the webGUI by clicking on the unmount button. I cannot track why the filesystem of this disk is not recognised by the plugin. Any idea? Thanks

I confirm this! Thank you for your information. I have a windows workstation and I started noticed in the event logger errors related to whea (every minute), but the system run smooth without crashes, for days. Memtest showed no errors for all the ecc ram modules. When I installed unraid I noticed errors related to cpu hardware and memory; by removing the faulty ram module both errors don't show anymore.

Hi, here is my dump, Nvidia Geforce GTX Titan black. Vbios: 80.80.4e.00.01 Tested and working. GTXTitanBlack.dump

Thank you very much, can you please explain how to put things together? First command extracts kernel folder with intel/amd microcodes in a cpio archive named microcode, second command extract all the system folders/files. Once changes are applied, how to recreate the cpio bzroot archive? Thank you Update: solved! Just extract the kernel folder into the folder with the system files, then compress the new bzroot with this command: find . ! -name bzroot | cpio -o -H newc | xz --check=crc32 --x86 --lzma2=preset=9e > /folder-to-bzroot/bzroot lzma2 compression is ok.

Hello everybody! After spending 2 days to get high sierra working on esxi with gpu passthrough without success I switched to unraid. Thanks to SpaceInvaderOne for his helpful and very detailed tutorials, that saved me a lot of time. I think I'm very closed to my target, i.e. having a working vm with high sierra with gpu passthrough, anyway I'm experiencing the following problem. The gpu I want to passthrough is a GTX Titan Black. Following SpaceInvaderOne's tutorial in the first post (including the gpu passthrough) I'm able to have a remote desktop session to the vm, the gpu is seen by the os, but nothing is displayed on the primary video, attached to the unraid server and connected with a vga-vga cable + vga+DVI-I port adapter. The GTX titan black is the only gpu on the unraid server. When I switch on the osx virtual machine the monitor goes black, such as if there is no signal output from the gpu. I then followed the SpaceInvaderOne's tutorial to dump the bios of the GTX Titan Black and made changes to the xml of the vm accordingly. Now when the vm is started I can see on the primary display the clover bootloader window, then I can see the apple logo with the progressive bar, but when it switches to the osx login screen the monitor returns black, such as if it losts the signal. However, I can connect to the vm through remote desktop (splashtop). The GTX Titan Black has two dvi ports (DVI-D and DVI-I), one HDMI port and a DisplayPort. Maybe the signal is switched to hdmi, or DVI-D or displayport from DVI-I? Unfortunately I can't connect to other ports other than DVI-I to check. Anybody knows what can be the problem? How to output video signal to DVI-I port? Thank you very much to all! Update: with additional flag nv_disable=1 in clover my monitor is working, but as expected the gtx is no longer a gtx with 6gb of ram Update2 - Solved! Finally I solved! Here is the solution: From tonymacx86 --> The MacPro6,1 and iMac15/17 perform special functions on their specific OEM GPUs/Displays. The MacPro6,1 unloads 1 GPU (with no ports) and leaves one functional for it's pseudo CrossFire function. The iMac15/17s apply a special EDID for their 5K displays. For non-Apple hardware, This can cause your GPU not to send a signal to your monitor (black screen) at boot while using the MacPro6,1 (Mac-F60DEB81FF30ACF6 board-id), or iMac15 (Mac-42FD25EABCABB274 or Mac-FA842E06C61E91C5 board-ids), or iMac17 (Mac-65CE76090165799A or Mac-B809C3757DA9BB8D board-ids) system definitions. If this is happening to you, your system will still be responsive but have no signal coming from the GPU's ports to the monitor. The solution I adopted is a patch with the AGDPfix.app v. 1.3, which can be downloaded for free from: https://www.tonymacx86.com/threads/black-screen-with-macpro-6-1-or-imac-15-or-imac-17-system-definition.183113/ Thanks to shilohh and to all who contributed for providing the solution.
