I can concur, disabling the serial port on my Supermicro X9Dai fixed the audio outages on my Presonus Studio 68c (on USB2.0 and USB3.1) with a Sonnet Allegro USB-C PCIe Card on Catalina 10.15.3

Hi, this EFI Folder contains the Setup for: SM X9Dai Dual E5-2670v1 Radeon VII (Slot-5) Both integrated Ethernet Cards USB2.0 + Renesas USB 3.0 (with mXHCD.kext) Audio (ALC889) is not working because of instabilities with GPU Set your Bios to default, then change the following settings: Chipset...

Issue resolved: Dont use @RehabMan newest USBInjectAll.kext 0.7.1, use 0.7.0. He stripped relevant EHCI entries!!

I need some help: I had to switch to imacpro1,1 SMBios because my new Radeon VII was freezing all the time with MacPro6,1. I have a X9Dai with Dual Sandybridge E5-2670. USB2.0 has stopped working, they worked well in MacPro6,1 by only renaming the USBE and EUSB to EH01 and EH02 and using the...

There is no XMP Setting in the X9Dai Bios, unfortunately.

Hi, seems like Audio is working fine

Hi, I ran a Sapphire Radeon VII on my x9Dai Dual E5-2670. Newest Clover and Lilu/Whatevergreen. Always after a while mostly opening Dialog Boxes, I get the Umbrella spinning a while, and then the Mousepointer vanishes and the Gui freezes completely. Backup, Disk Activity still goes on. ARD...

By the way, I tried the reflashing with the following Subvendor/Subdevice IDs: Sonnet/Oyen and High Sierra 10.13.2 With Sonnet, nothing worked. With Oyen, it worked, but had the same crashes on shutdown and disconnecting of devices as with the GenericUSBXHCI.kext

Does anyone have Problems since 10.13.2 with GenericUSBXHCI.kext? Since the Update, my Renesas uPD720200 (Vendor: 1033, Device 0194, Sub Vendor 8086, Sub Dev 4953) always causes a crash on shutdown with the GenericUSBXHCI.kext and also with the mXHCD.kext from this thread. It worked til 10.13.1...

I run El Capitan with 6,1 SMBIOS. All works fine. I had to edit the info.plist in AppleUSBEHCIPCI.kext. I copied the MacPro5,1 Entries and renamed them to MacPro6,1. I used the AICPMPatch.pl and for the MSR and the Clover Patch for the AICPUPM kext. I use the AGDPfix AppleScript to remove the...

Black Screen with MacPro6,1 or iMac15 or iMac17 System Definition Hi, what does you mean? I have GTX770, there is no entry in the DSDT with GFX0/1. I have nvda on npe3 in my dsdt. Can you explain further? Or is this only true for integrated Intel GFX? Thanks

This is I guess a system thing, had the same experience with yosemite and el capitan, as well as with the dsdt patch and the edited i210 vanilla kext. Sometimes it simply does not get an ip and gets online. I the reboot as long as possible, and most of the time it is stable now. There is some...

So for the SmUUID, use the uuidgen Terminal Command. For the Board Serial Number, I always Use the Serial Number which is generated by Clover, and add it up to 17 Digits (current macs have a 17 Digit Board Serial Number). I only use HEX Numbers (0-9,A-F) and mix them. Take a look at this...

Never EVER use Serial or UUID from a real mac. This can cause unpredictable issues with Imessage and other cloud stuff. Generate a new SMBIOS and all other stuff from Clover Configurator. Open a Terminal and use the command uuidgen to generate a UUID. Use this uuid.

You´re welcome. Yeah I know the AppleGraphicsControl Patch but I always try to stay as vanilla as possible. From what I know, the Mac5,1 SMBIOS just have only two C-States so there have to be some patching as well. So you can either choose bad or bad, you have to patch anyway. (I never tried...

Hi, to use AICPM + SSDT you have to use imac or macpro6,1 smbios with sandy bridge as well as ioplatform kext, or did you get it working with the 5,1 SMBIOS? I was not able to test so far, in the midst of a project... But with Yosemite and 6,1 SMBIOS things were working... Attached my...

Hi, use my patched DSDT (attached) with original AppleInteli210 Kext. Delete all Patched Kexts and use only the dsdt with clover. In the clover Kexts Folder I have only FakeSMC and VodooTSCSync I also renamed USB to EHCI. They work with El Capitan (only USB2.0) and MacPro 5,1 SMBIOS...

Please see post #13.

Just follow my guide substitute yosemite with mavericks. It should work as well. Try to boot with GraphicsEnabler=yes and cpus=1 or set clover to inject nvidia. I guess your Quadro 4000 is not supported OOTB, so you should use GraphicsEnabler or inject nvda until you are able to install the...
