Help! For several weeks I still can't get Ventura to start, yet I have three identical machines and it doesn't work. I even tried different versions of the Bios... Note : and I have 3 identical computers T5810 that have the same problem. I have done dozens of tries with 2 USB keys : No problem to copy paste the UEFI and the bios mount the USB-2 key, No problem to launch Clover or OpenCore, but once you choose Ventura, there is always the same error. There is therefore a parameter that must be changed or that does not work, which prevents me from starting the macOS Ventura installer. I did : 1. I put the Bios on UEFI instead of Legacy. 1. I used Ventura Olarial (download from the forum) to make the USB key in disk image with Balena Hetcher. 2. I took the UEFI which I decompressed then copy/pasted into the volume of the UEFI partition of the USB key CLOVER.X99.zip or EFI.Opencore.Desktop.HEDT.Haswell-E.zip (for x99) I did it with Clover which allows settings and OpenCore and the result is unfortunately the same, when I start on the USB key: and nothing more... Why can't I create a viable and functional startup key? Which parameter is missing? I forgot some things???

Depuis plusieurs semaines

thanks Maldon all point is okay, UEFI not legalcy , all is usb 2 and the key, I copy past the EFI and I mouth the folder with ESP Mounter Pro and I empty the trash. It's a quadro Nvida card (with 4 port) not a IGPU Yes have click on the NVRAM or F11 with clover (I have try both) ... Same problem again... With the bios A09, the pc reboot immediately , but with bios A34, it's freeze... I try with 2 different USB key 2.0 and EFI HEDT.Haswell-E.MOD maybe the hardware is to old for ventura

I try to downgrade the Bios like this https://github.com/OreyM/Hackintosh-Dell-T5810-Xeon-E5-26xx-V3-OpenCore-PowerMac-G5 now I have the 09 version of bios but i try to use older clover solution and I have a graphic card error... Maybe is not compatible with Ventura macos ... this photo is the result with the clover from the github link above and the bios in version 09. If I use Clover or opencore with ventura for x99 from olarila, then it restarts in a loop. I'm going crazy... do I have to use an old macos?

3 days I try but there are a few things i didn't understand, i think... now I installed clover to change everything... Q: Do I have to change the efi on the usb key, or that of the menu that is loaded from the ssd disk? I still can't boot into the macOS usb key installer... I try different configurtion, the usb-key with open core I try this boot args : -v alcid=12 watchdog=0 -no_compat_check -radvesa -disablegfxfirmware But same result

Freeze with the USB-2 key (try with 2 different ones) to install your Ventura version, any suggestion ? unable to install... Note: EFI opencore Haswell-E (Intel X99 chipset: LGA 2011-3) nothing happens after, the key stops making light...

maybe it's the args need to change, but how to do with opencore, there is no menu like on clover? when I press the spacebar it's Reset NVRAM that does the toggle, how do you do it? I do not know how to do and what to do to manage to install macos, here is the display which freezes after having started on the key... I use the EFI.Opencore.Desktop.HEDT.Haswell-E.MOD.zip for a Dell Precision T5810 workstation with Xeon E5-1650 v3 processor (Intel X99 chipset: LGA 2011-3) year: 2015 GPU is AMD... Whats wrong ???

The Dell Precision T5810 workstation with Xeon E5-1650 v3 processor is a Haswell-E processor (x99 Chipset) , the computer is from 2015... thanks!

-Desktop HEDT Haswell-E Download HERE (x99 Chipset) -Desktop HEDT Broadwell-E Download HERE (x99 Chipset) which one ???

what EFI do I need to put on the SSD, I'm stuck and I can't find the solution. Intel® C612 Chipset Intel® X99 Chipset where I find the corresponding EFI folder, any link please ? here are the characteristics of the T5810 found in the link on the case : https://ark.intel.com/content/www/us/en/ark/products/codename/44349/products-formerly-wellsburg.html https://www.intel.com/content/www/us/en/products/sku/81759/intel-c612-chipset/specifications.html Thanks a lot.

thanks , but which EFI , I need?

I need to install the EFI folder with EFI mounter on the new SSD. Which EFI should I use for DELL Precision Tower 5810 ? And I have to make changes in the BIOS? THANKS DELL Precision Tower 5810 (T5810) year 2015 GPU: NVIDIA Quadro CPU: Intel® Xeon® série E5-2600 RAM : 16 Go

My hackintosh works perfectly with Mojave (olarila version) What is the best way to update macOS ? Actual version: 10.14.6 Mojave from Olarila image wanted version: Monterey CPU: INTEL 8 Core i9-9900K 3.6GHz Motherboard: ASUS ROG Strix Z370H GAMING RAM: 32 Go GPU: SAPPHIRE RADEON RX VEGA 64

thanks, I know but it's not working with the dosdude tool. macOS reboot infinitely after the half of the loading system. I have update the firmware, but nothing change, it's for that I try with Olarila... have you a configuration for Clover? High Sierra works and I have use Mojave but it's down after a apple update macbookpro7,1 with 16Go RAM and 2 SSD My problem with clover or directly with our version or installer dosdude tool patcher : impossible to boot the installer key

Problem install on MacBookPro7,1 Mid-2010 I try config2 but same problem... High sierra works, but not Catalina
