  1. I'm trying to pass my RX 560 video card, my ethernet port, and one of the usb busses to a virtual machine, but so far I'm getting nothing on the monitor. Everything worked fine before I tried to passthrough. My computer is running ubuntu 18.04 as the host OS The motherbord is a Gigabyte ga-x79-ud5, the CPU is an i7 3930k, there's 32GB of RAM, and I have 2 videocards, RX 560 and GT8600), which are each connected to an HDMI port on my 4K monitor (actually it's a Sony 4K TV) My QEMU script is based on https://github.com/kholia/OSX-KVM/, but I also used a few other sources. #!/bin/bash qemu-system-x86_64 -enable-kvm -m 24576 -cpu Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check \ -machine q35 \ -smp 8,cores=4 \ -vga none \ -device vfio-pci,host=02:00.0,bus=pcie.0,multifunction=on \ -device vfio-pci,host=02:00.1,bus=pcie.0 \ -device e1000e,host=00:19.0,bus=pcie.0 \ -device usb2,host=00:1d.0,bus=pcie.0 \ -usb -device usb-kbd -device usb-tablet \ -device isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" \ -drive if=pflash,format=raw,readonly,file=OVMF_CODE.fd \ -drive if=pflash,format=raw,file=OVMF_VARS.fd \ -smbios type=2 \ -device ich9-intel-hda -device hda-duplex \ -device ich9-ahci,id=sata \ -drive id=Clover,if=none,snapshot=on,format=qcow2,file=./'Mojave/CloverNG.qcow2' \ -device ide-hd,bus=sata.2,drive=Clover \ -drive id=Virtue,if=none,file=Virtue.img,format=raw \ -device ide-hd,bus=sata.3,drive=Virtue \ -netdev tap,id=net0,ifname=tap0,script=no,downscript=no \ -device e1000-82545em,netdev=net0,id=net0,mac=52:54:00:c9:18:27 \ I used the following commands to identify my devices ~$ lspci -nn|grep -i vga 02:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

Any help would be appreciated.
  2. Thanks onemanOSX. That looks like a great source, I tried to use his guides, most of what he says is so over my head I'm getting a {censored} headache just from trying to figure it out. It's probably going to take a while just to be abler to know enough to follow the steps he laid out. If a make any progress I'll let you know.
  3. Thanks Hervé Cool, but I never used Mojave. Is Mojave better than any of the earlier OS's given my hardware? I want to have the most stable system I can, and my old iMac ( running Mavericks) used to crash/ freeze several times a month. No it has 4 hard drives and an SSD. The drives each have between 2TB and 4TB on them. Is there a driver for them that would't take up too much RAM/CPU and be fairly fast; Or do I need to convert them to Mac format? Could you elaborate on why? I get that KVM is hard to set up, Are there anything specific that makes it problematic? I know that the drives would look like network shares, but does that mean they would be a lot slower? From what I've read I could assign the Radeon card to the mac, and use the geForce for the main Linux system. Are there any limitations to this? Will it give me 4K? My cousin told me she never had a crash or freeze with Linux, if I installed could I keep the main system up and runing when the Mac crashes. The system is also being used as a media server for the whole house. Ive seen a lot of guides, but most of them assume the reader knows way more than I currently do, and are geared toward multiple configurations. For every line I read I have to do hours of googling to try to understand it , and still can't tell what applies to me and what doesn't. Do you have a URL of a guide written for a newbie like me, who not long ago would enter commands in my web browser, because I never knew about the terminal. Sorry I'm such a lamer, but I really could use all the help I can get. Thanks again,
  4. Hi everyone, Recently my cousin gave me her old computer after my iMac died. The computer has the following specs Operating System: Ubuntu 18.10 CPU- Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz RAM: 32951888 KiB Motherboard: X79-UD5 Graphics: 3840x2160 Radeon RX 560 1920x1080 GEForce 8600 GT Audio:HDA-intel-HDA ATI HDMI device: /dev/sda size:80GB model: Intel SSDSA2M080 UUID :0e2e84f4-654d-4f20-8ee2-bb2aacfd8d78 Partition type:ext4v1.0 Label: System device: /dev/sdb size:6TB model: HUS726060ALA640 UUID :1cd62e3c-5215-47d5-8527-dc541c4839ef Partition type:ext4v1.0 Label: Movies device: /dev/sdc size:6TB model: HUS726060ALA640 :e38b5238-a8ac-4d02-9eac-d72984257041 Partition type:ext4v1.0 Label: TV device: /dev/sdd size:size:6TB model: HUS726060ALA640 UUID :c47b6498-58a1-d706-949e-683e68ca5613 Partition type:ext4v1.0 Label: Porn device: /dev/sde size:6TB model: HUS726060ALA640 UUID :e38b5238-a8ac-4d02-9eac-d72984257041 Partition type:ext4v1.0 Label: Snap-Parity I've never used anything but OS X (currently mavericks) on a regular basis, and I don't really understand technical stuff very much. Most of the stuff on this forum goes right over my head. My cousin said I would be better off keeping the main system Ubuntu: since the drives are set up as a snap-raid using a file system that isn't mac compatible, and that I should make a kvm to use as a mac. Would that be better/easier than converting the drives to apple file system, and installing directly as the main OS? And what OS X version would be best to use given my hardware? Also is there a step by step guide, that is written for newbies like me? Extracting the relevant information from multiple sources, and piecing together what I need, is beyond my skill level. Thanks
