Because you're getting "Valid Purchase Date, ..." it means your serial number has been taken by a real Mac owner. You should immediately change your serial number. And remove that computer from your iCloud settings. Changing serial number can require some apps to be relicensed.

This brings up a good point. Whenever anyone uses a current SMBIOS, of a Mac that Apple still sells, it's a good idea to check the serial number (every month or so) you generated for that model of iMac or whatever you've selected. Just because it wasn't in use previously doesn't mean it isn't today. For an SMBIOS of Macs no longer in production it shouldn't make any difference. Many people use iMac 14,2 or 15,1 for older hardware and those went out of production over 5 years ago. There aren't any new ones being sold now.

Ahh! I was using PList Pro 1.9.2 (paid version) to edit the setup. Is OC Config now safe to use without risk of corrupting the setup file? I was warned off it earlier in various forums. What say you?

FWIW, I'm using the BIOS "Z390DESIGNARE.F9h" which allows me to flip the CFG lock in the setup screen.

OpenCore Configurator is amazing and wonderful. It still gets a bad rap from those who used it in the distant past. But things change, and attitudes should as well.

Hi Casey, I tried deleting the CMOS, but the problem still persists. I did the SSDT with the guide you gave me, and the one you recommended was more precise, since I did not duplicate ports and the names appeared correctly. If I don't connect anything to my TR but I enable GPIO3 Force power, it gets stuck on startup showing this message ...

PS: I'm also going to leave a picture of my connection, since I only have 1 6-pin connector left on my motherboard, I couldn't give it more power, could that be the problem?

The extra 6-pin power connector is not needed unless we want to charge a laptop or other high-power device.

Were you able to capture screenshots of Thunderbolt settings? If not, check if there’s a Thunderbolt Boot Support option in BIOS. If so, try each of the available pop-up options to see what effect they have.

or maybe the serial number says valid because it has been activated on a hack?

hello casey, I think I have tried each one of them, the problem is when I enable force power giop. The only way I could make it work, was connecting a device (iphone with usb c cable) I still do not have any thunderbolt 3 device, I am waiting for my apollo x4 to arrive

Technically, the UAD Apollo x4 will work without flashing the Thunderbolt firmware. Some of the higher bit rates and lower latencies, however, can only be realized with flashed firmware. Because you purchased an already-flashed GC-Titan Ridge from eBay, we don't know which firmware was used.

Have you tried to flash firmware yourself?

Or do you have a non-flashed GC-Titan Ridge or even a non-flashed GC-Alpine Ridge?

When the UAD Apollo arrives, it's likely that you will always have it connected. So the system might boot successfully each time because it seems something has to be connected to your flashed GC-Titan Ridge in order to boot macOS.

I've added the following note to the OC 0.6.0 Guide:

Kinda funny I was going to ask before checking the latest posts ,why IntelMausi 1.03 was not included in the OC-0.6.0-DESIGNARE-Z390.zip

The OpenCore 0.6.0 ZIP for Designare was based on the 0.5.9 ZIP for Designare in which the same IntelMausiEthernet 2.5.1d1 kext has been present for the past two months. No complaints or issues were reported so the same driver was retained in the 0.6.0 ZIP.

In the OpenCore 0.6.0 ZIP for Z490 Vision D, however, IntelMausi v1.0.3 is used.

It shouldn't, because hack serials never get entered into the Apple database because they didn't "make" a machine with that serial and sell it.

Although Section 8 of the Quick Reference spoiler in Post 1 lists all of the necessary guides, I have not created a single consolidated guide that covers all steps from A to Z in one post. This is intentional. It's meant to be somewhat discouraging. Flashing the controller can damage the board if we're not extremely careful in attaching and detaching the SOIC clip. It requires excellent near-sighted vision and steady hands. But the procedure, once applied successfully to the on-board controller, produces better results than any PCIe add-in-card.

I figured that it was intentionally left that way, I know you mention multiple times it is not a process that is for beginners. That's primarily why I have left it alone, although I have excellent vision what I don't have is a beyond steady hand although I'm sure I could manage I rather not risk it. Let me ask you though @CaseySJ what does flashing this firmware on the onboard chip allow us to do? I've never actually seen what it allows indifference.
