How to build your own iMac Pro [Successful Build/Extended Guide]

[shael]

Gorgeous, man

Thus flawless and absolutely native XHC USB Implementation with top speeds not only at USB3.1 Type-A and Type-C but also at USB3.0 level. All USB2.0, USB3.0 and USB3.1 Type-A and Type-C ports work as expected.

Thanks for your extensive efforts in conforming my expectations..

With these marvellous and impressive results, I definitely consider the XHC USB discussion as closed!

I do not want anybody to come up once more along this thread with complains about USB performance or USB functionality on our gorgeous Skylake-X/X299 iMacPro builds.

He will be immediately directed to post #3623 by @shael ...

minus the fact, we still have the external/internal issue: which ive documented to try and fix whenever i get a chance. but no rush for it...

Try to use XHC instead of XHCI and see if the icon behaviour changes at equal USB port performance and functionality...

You need again to introduce a ACPI patch and once more change to variable in the SSDT-X229-iMacPro.aml.

Report back with results!

Enjoy and have fun

P.S.: Me personally, I care a *** about the external/internal USB icon issue you are that worried about. If you want to change this last minor and purely cosmetic issue go ahead, but do not only complain and distribute the related work to others.

By the way, I fixed the problem with the XHC USB ports. I would have expected a bit more emotion and gratitude at your side.

Cheers,

KGP

i appreciate your help, however i dont believe the usb aspect of this board is perfect quite yet. thus the gratitude is received upon completion. However with that being said. thank you for all your help thus far.

the issue is that this is not as simple as a cosmetic issue. the external drives when shown as internal are not ejectable and thus could cause issues with the drive.

EDIT: no boot with xhc. i think this may be because clover can only do a replacement with the same character count

Next significant Guide Update

New EFI-Folder distributions have been attached at the bottom of the originating post/guide of this thread and are once more attached here below.

EFI-Folder related changes:

• XHCI -> XHC1 ACPI DSDT Replacment Patch removed from config plist contained in EFI-X299-10.13.2-Release-iMac17,1-120118.zip and EFI-X299-10.13.2-Release-iMacPro1,1-120118.zip

• EmuVariableUefi-64.efi removed from EFI-X299-10.13.2-Release-iMacPro1,1-120118.zip

Guide related changes:

• New SSDT-X299-iMacPro.aml implemented and attached at the bottom of the originating post of this thread/guide as well as here below. The new SSDT-X299-iMacPro considers the above change of variables XHC1 to XHCI.

Amazing news and conclusions:

With AptioMemoryFix.efi, SMBIOS iMacPro1,1 under 10.13.2 (17C2120) and 10.13.2 SA (17C2205), we reached native NVRAM implementation, thus EmuVariableUefi-64.efi has been removed from the /EFI/Clover/drivers64UEFI/ directory contained in EFI-X299-10.13.2-Release-iMacPro1,1-120118.zip! Thanks to @Menno87 for confirming the expectations

With the removal of the XHCI -> XHC1 ACPI DSDT Replacment Patch and the XHC1 to XHCI variable replacement in the SSDT-X299-iMacPro.aml, we finally reached fully native flawless XHC USB port implementation for ALL X299 mainboards. Top USB speeds not only at USB3.1 Type-A and Type-C but also at USB3.0 level. All USB2.0, USB3.0 and USB3.1 Type-A and Type-C ports on the ASUS Prime X299 Deluxe are fully functional and work as expected. Many thanks to @shael for his extensive verifications and tests

The guide has been updated with respected to this new implementations and findings.

Enjoy and have fun

Nonsense, sorry: All USB Flash Drive devices are ejectable on the Desktop, but just show the wrong Icon colour. USB HDD and SSD drives can be ejected in the "Finder"..

Man... you never give up, right? Permanently insisting and insisting... complaining and complaining... demanding and demanding.. and finally spreading misleading and incorrect information and conclusions..

What should I do with you?

i never demanded anything from you. i post in here asking a quesiton and i solve my own issues for the most part. im just wondering if anyone else has had the issue before i waste my time fixing it.

i guess get me banned because of a language barrier. there is a misunderstanding with the issue.

BTW, despite the APFS File Format of my 10.13.2 SA (17C2205) System Disk (at present SSD and not even NVMe) and having TRIM enabled, the time for booting my Skylake-X/X299 iMac Pro System reduced from 50 sec. to now 5-8 sec. after the clean install.

Absolutely no issues with apsf.efi and the APSF SSD
