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

[RuleBreaker01]

I just noticed something and it may not be something new for people here....

but on a real Mac keyboard (white wired with numpad) and real Mac display (27" Apple LED Cinema Display via miniDisplayPort>DisplayPort) F14 and F15 are now brightness controls. This is without any applications running.

I have an Apple keyboard, and brightness is over the F1 and F2 key, and you can clearly see that it's still the case on all the new apple keybard:

I change the contract on my mac pro and macbook pro using F1/F2
And if my Apple screen is plugged to my windows PC and I use the Apple usb keybard, i also change the contrast using F1/F2

F14 and F15 are not mapped to anything by default on my macs.

Awesome thank you...

Both are AMI bios, and the DSDT are almost identical, can easily see where the two TB3 ports are inserted...

So the gigabyte ACPI table doesn't have an EC device like the asus does.
EC is Embedded Controller according to http://www.acpi.info/acpi_faq.htm

I wonder if that's the reason I haven't been able to successfully put the gigabyte to sleep and then wake-up when I press a key

Hot Plug is already working with ssdt or patch in clover.

The screen capture shows that the TB3 card had device Id 1577...

If I understand properly however, this is just for the devices to appear in the PCI list as shown in the System Information app in a user friendly fashion.

If so, how could this add any features such as hotplug?

Hey guys, did anyone has try to update the firmware on your samsung nvme drives? Will the macOS system & clover stay intact?

For working hot plug only this entry is needed

This entry will not show in PCI device but it necessary for working hot plug

Of course firmware is one thing clover and data partition are another thing..

Guys, here some kind of first noob question from my side

Currently building a iMac Pro system for somebody with 1x Vega Frontier and a LG 38UC99-W. While under Windows and OSX everything behaves as expected, the screen resolution of the ASUS Splash Screen and the screen solution during boot is ugly and by far too low.

Any solution?

Do you have CSM disabled?

same here. It is a LG monitor / Vega problem.

With a Philips UW monitor is boots with the correct resolution.

And same problems with 980TI and LG, ugly resolution, with Philips looks perfect.

Some cards don't work with the LG UW.
