Hai Ngo

I have installed Monterey and everything working with 1 CPU so starting from fresh is gonna take a lot of time. Only with 2 CPU setup I get stuck at [EB|#LOG:EXITBS:START]. Do you have any idea with the info I provided?

I have almost everything working with single CPU E5 2689 on my China X79 motherboard which 2 sockets as illustrated with the picture below But with dual CPU setup, I get stuck at [EB|#LOG:EXITBS:START]. I followed all instructions here but there is still no luck. Could anyone give me suggestions to fix this issue? Here is the info of my PC Mobo: Chinsese X79 dual CPU CPU: Xeon E5 2689 x2 GPU: Gigabyte RX 480 4GB Ram: 4 x 16GB 1600Mhz Also please find my EFI and the log file in the attachments EFI.zip log.zip

I still cannot boot into macOS installation in USB. Here are screenshots before the prohibited sign appeared with and without Usbinjectall Could you give me some suggestions to fix this issue? @MaLd0n Could you tell me how did you get the DSDT file you gave me? It fixed the my memory panic issue so an explanation will be useful later I believe

I've already used usb 2.0 port and sata has already be set to AHCI. I've just removed usbinjectall kext and the prohibited sign still appears

I've overwritten your file and removed cpus=1 flag, now the memory panic is gone but I get the prohibited sign with broken texts on the screens.

I'm trying to install macOS on my X79 rigs which are bought from Aliexpress and having some issues: I cannot boot without the flag cpus=1 as I always endup with a memory panic message. If I boot with flag cpus=1, it takes quite long to boot into Installation screen. After reboot from the installation (I'm trying to make an internet installation), I cannot pass the apple logo screen with the text "Estimating time remaining" which seems to last forever. Could you give me some suggestion to boot the without flag cpus=1? I'm suspecting it's causing the long lasting "Estimating time remaining" message and my pc possibly won't run at full speed if the macOS installation succeeds (I'm using 2 cpu Xeon E5 2689) Here is details about my rigs: Mobo: Chinsese X79 dual CPU CPU: Xeon E5 2689 x2 GPU: Gigabyte RX 580 8GB Ram: 4 x 8GB 1333Mhz Here is some of my BIOS settings: Legacy USB Support: [Enabled] XHCI Hand-off: [Enabled] EHCI Hand-off: [Enabled] Hyper-threading: [Enabled] Active Processor Cores: [All] Serial Port: [Disabled] Intel(R) VT-d : [Disabled] Launch CSM: [Enabled] Boot option filter: [UEFI only] Launch Storage OpROM policy : [UEFI only] Launch Video OpROM policy : [UEFI only] My EFI folder is in the attachment EFI.7z
