iMacPro SMBIOS and new horizens

Yes it hasn't been merged with the main macOS releases that's why we need to add the board-id and the SupportedModelProperties into the platformsupport.plist manually.

But there is a specific macOS update for iMacPro computers which is available on Apple's website and through the AppStore.

If I create USB installation, where I should add platformsupport.plist manually?

If I create USB installation, where I should add platformsupport.plist manually?

If you follow the guide provided in the first post under the D2 section you can download the macOS install app and then you can create the iMacPro version of the installer and you won’t be needing to edit the platformsupport.plist

 

In addition the platformsupport.plist is placed under:

 

/System/Library/CoreServices/PlatformSupport.plist

 

Which I guess is not present on the usb installer anyway. I don’t have access to my computer right now too see where it is placed on a usb disk installer.

There are two PlatformSupport.plist files in the USB installer

 

1. /Volumes/Install macOS High Sierra/System/Library/CoreServices

2. /Volumes/Install macOS High Sierra/.IABootFiles

 

You need to add the board-id and the SupportedModelProperties to both files, or simply edit one of them and then copy it to the other path.

Ok,

After attempting to boot from macOS USB installer which I created by using the regular macOS 10.13.3 I get the following error

9254d822a2137edef52676efefda13fb.jpg

 

So I guess we still need to wait for an official release by Apple or we can use the instructions given by @KGP-iMacPro in the D2 section of his guide.

Boot from recovery partition and select clean install from menu. Or if you have working osx partition extract from installer: BaseSystem.dmg mount it and select installer. In both situation installer will download most recent osx version for your machine.

I already created the macOS 10.13.3 installer for iMacPro. It was just a test to see if adding the iMacPro board-id and the SupportedModelProperties to a regular installer should suffice or not.

 

But thanks for the tip anyway :)

I had to jump through hoops at the beginning. I changed the platform support plist and SMBIOS, then I did an app store install to a fresh SSD, luckily there was an OS update at that time. I think 10.13.4 or even later 10.13.3 updates are no good for this (you get the current version being newer than the intended install). Find an older 10.13.3 version and install that to your fresh SSD then upgrade that one maybe.

Once I had that fresh install with an Imac Pro version I didn't need the platform support plist hack.

Then I migrated my stuff to the new install and voila!

Now it's just upgrading imac pro to imac pro no worries.

 

On X299 it seems definitely worth it, with a very stable system now on 10.13.4

If you making installation online from recovery or from BaseSystem.dmg there no need to make any modification of platformsupport.plist or smbios changing. installation will download version for iMacPro.

I just completed the installation on my Skylake rig and the lags are still here, not as bad as iMac17,1 but I still have the lags in Safari and Dock.

 

My CPU only has three steps 800 Mhz, 4.00 GHz and 4.10 GHz

I activated the Intel HD 530 to see if that can help but it didn't.

I had a few hours to spare and did a small experiment with my Skylake X rig.

I tested 1,1, 18,3, 17,1 and 6,1. (Fabio is right, the same 10.13.4 works for all of them without patching)

My config plist is super vanilla now and no patches for anything except USB, and that's not even very important - gives me 2 extra ports which I don't use anyway.

 

Oddly, 6,1 gave me about 8% better GPU - in geekbench anyway (178000 from 155000). Cinebench was a couple of percent better.

imac pro 1,1 was the worst of them by a few percent.

 

I still think that, being the last Mac without GPU and designed for expansion, the 6,1 SMBIOS seems to work just a bit better. I'm looking forward to next years Mac Pro for this reason.

 

So anyway, does this lag in the nvidia drivers happen with all the SMBIOS?

 

edit: the other bonus on 6,1 being that I get 2 monitors on dp, rather than 1 on HDMI and 1 on dp with all the other SMBIOS....

here is iMacPro the best, 183k Geekbench, Luxmark 25383

MacPro6,1 175k Geekbench, Luxmark around 25300 = the same

 

CPU no changes

 

i think GPU performance is affected by GPU temps? My Vega has a full water block, after Luxmark it shows @ 30°

Hmmm...how to change SMBIOS to iMac pro? my clover don't have this option...can anyone guide me?

Thanks

 

You need to use Clover Configurator and under the SMBIOS section you can change it to iMacPro1,1

thanks Cyberdevs but my clover don't show this...which version are you using?

I'm using v2.4k r4439 

My Clover Configurator version is 4.61.0.0, What you are referring to is the revision of you Clover Bootloader which is r4439.

Download this version

Clover configurator is an application which helps you to edit and reconfigure the config.plist (and other stuff in the EFI partitions such as drivers, bootlog etc.)

 

The version of your Clover Configurator is old and it has no iMacPro SMBIOS settings.

I have adopted the Smbios iMacPro on my H81 rig since i began my X299 build. I have updated to 10.13.4 SU (17E202) by terminal command with no issue :)

I had a few hours to spare and did a small experiment with my Skylake X rig.

I tested 1,1, 18,3, 17,1 and 6,1. (Fabio is right, the same 10.13.4 works for all of them without patching)

My config plist is super vanilla now and no patches for anything except USB, and that's not even very important - gives me 2 extra ports which I don't use anyway.

 

Oddly, 6,1 gave me about 8% better GPU - in geekbench anyway (178000 from 155000). Cinebench was a couple of percent better.

imac pro 1,1 was the worst of them by a few percent.

 

I still think that, being the last Mac without GPU and designed for expansion, the 6,1 SMBIOS seems to work just a bit better. I'm looking forward to next years Mac Pro for this reason.

 

So anyway, does this lag in the nvidia drivers happen with all the SMBIOS?

 

edit: the other bonus on 6,1 being that I get 2 monitors on dp, rather than 1 on HDMI and 1 on dp with all the other SMBIOS....

 

I am using MSI X299 Tomahawk AC but in my config.plist, I am unable to boot without some VoodooTSCSync.kext.I created a custom kext for my 10-Core i9 7900X. I also have to use Rename oem _DSM to ZDSM as DSDT patch. Without these 2 things, my hack refuses to boot. I am using latest version of AptioMemory.efi.

 

How come you are able to boot vanilla? BTW 10.13.4 here.

 I'm not surprised because the the MSR 0xE2 register is locked and therefore not writeable so you must boot with  VoodooTSCSync.kext and TCSadjustreset.kext take a look about the guide here for X299 build https://www.insanelymac.com/forum/topic/331658-how-to-build-your-own-imac-pro-successful-buildextended-guide/

You just need VoodooTSCSync.kext OR TCSadjustreset.kext, not both. They do the same thing.

I also use OsxAptioFixDrv-64.efi, but don't need AptioMemory.efi or Rename oem _DSM to ZDSM.

I don't have any DSDT or SSDT. But I don't use TB or any PCI cards except the GPU.

I'm running 10.13.5
