  1. I'm giving up the idea of using a Mac Pro 4.1 as a NAS, the reason is power consumption. The standby for a Mac Pro 4.1 with an Intel L5640 is 100 watts, this is less than ideal.
  2. Thanks. I'm thinking long term support, even a temporary hack make it working on Mac Pro, I'd have to modify the installation every time when there is a new release which I don't prefer. Today I made some progress, it seems the best way for now is to run unraid in a virtualised environment, such as Proxmox EV.
  3. Just wondering why not go for 10GbE with SFP+, the switches are reasonably priced. Plenty of Mellanox cards cheaply available.
  4. Thanks, I just quickly tried it with my iMac. Unraid will boot and lspci seemed to show the Thunderbolt 3 bus. I plugged the QNAP QNA, nothing shows for the ifconfig. I will pass the idea for now.
  5. I had plan to use unraid with a Mac Pro 4.1/5.1, but it seems this is impossible at the moment. So I decided to get an Intel NUC or similar small factor PC which has Thunderbolt 3 and connect it with a QNAP QNA SFP+ adaptor. This adaptor has a known good compatibility with macOS, but I'm not sure if it will work with unraid. Am I going the right direction?
  6. I have also tried other Linux distros, including Fedora and FreeNAS, they all worked without problems. However, I only want to use unraid on this machine.
  7. There are other users experiencing the same kernel panic issue when booting unraid on Mac Pro 4.1/5.1 or Mac Mini 2009. I'm hoping unraid team can help to identify and solve this problem. In order to boot unraid on a Mac Pro, you must use the UEFI Boot with unraid. To isolate the issue, I have removed all the hard drives from the machine in later tests. I used a capture card to get a clear output of the kernel panic screenshot attached. I've tried 6.8, 6.8-rc8, 6.8-rc9, they all showed the same kernel panic. Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) -6 My Mac Pro was able to boot 6.8-rc6/7, as it has a different kernel (5.7) and it gave a slightly different kernel panic output generally removed the register section. I've also tried different USB drives and different USB ports (Mac Pro only has USB 2.0), none of them worked. Then I tried to append root=/dev/sda1. A little progress lead to a new kernel panic, now it has two error pieces: devtmpfs: error mounting -2 Kernel panic - not syncing: No working init found. Try passing init= option to kernel. Then I booted unraid in VirtualBox and verified that only /sbin/init exists, so I added init=/sbin/init to the kernel parameters. Then it showed a new kernel panic: Kernel panic - not syncing: Requested init /sbin/init failed (error-2) I don't feel confident with this error message, so I booted the USB drive in VirtualBox again and it started without a problem. This is where I'm stuck, could anyone please point where I should go?
  8. The same here, I followed other threads including Mac Mini 2009, it seems none of these can boot unraid.
  9. Reading other posts, it seems you need another boot loader (Plot Bootloader) resides in a CD to load unraid from USB.
  10. I'm glad that the setup works for your needs. I will wait for the 6.9 RC for another try before I convert the Mac Pro to a PC.
  11. I tried 6.8 and 6.8 RC7 and RC9. 6.8 RC7 gave a slightly different kernel panic output screen without the CPU #0 section. I’m having slightly hope to try the 6.9 RC with new kernels.
  12. My goal is to get the Mac Pro a 10GbE SFP+ card, an NVMe PCIE card + NVMe SSD (or U.2 SSD) to build a 10GbE capable unraid server for the "cheap". I like the Mac Pro because it uses ECC RAM and has server grade components which made it very durable. I'm glad that you found a workaround for the moment. Unfortunately, I can't bear the mind that Mojave introduces extra overheads for performance, stability and energy consumption. As Mac Pro 5.1 and older models lost OS support since Catalina, I assume more and more of these machines will end up on eBay and people will want to convert them into servers or PCs. I hope unraid an provide official support for this machine.
  13. Did you have any progress on this? I went through the same like you did with my Mac Pro 4.1. It is now flashed with the latest firmware 144, but it still shows the same error. I've tried to boot Fedora Live CD and another Linux distro, they all worked without issue. I do think this is unraid specific. I'm stuck and thinking of converting the Mac Pro into a PC.
  14. I've updated the BootRom to 144, yet no luck to boot unraid. The same error.
  15. Have you tried unraid on Mac Pro yet? It's only a matter of using a USB stick. For me, it doesn't boot at all and stuck with a kernel panic.
