Hello @purpose0,Hi @CaseySJ!
This is going to be my first post on this site since I started hacking way back when so I apologize if I'm not posting correctly but I'm in desperate need of help.
I've been trying to do a fresh install of Catalina on my system for weeks now and have gotten no where. I tried following your guide (Asus X99 Deluxe II) but I just get stuck with a black screen after the mac load screen for the install.
My specs are below:
Motherboard: Asus X99-A Deluxe II
CPU: i7-6950x
GPU: Sapphire Pulse AMD 5700 XT
Memory: 128GB G Skill
Dual Monitors: LG 29WK600-W 29"
NVMe SSD: Samsung 960 EVO 2TB M.2
Asus Hyper M.2 Mini: Samsung 960 EVO 2TB M.2
Asus ThunderboltEX 3 Card
Power Supply: Corsair AX860
CPU Cooler: Corsair H80i v2
Not sure what I'm doing wrong but I've tried the following:
My previous build was based off of KGP's original Sierra build and ran perfectly for years but trying to move out of the stone age now after my 1080TI card stopped working and nothing is as simple as it used to be.
- I loaded your exact EFI, Modified BIOS 1802, updated the PlatformInfo parameters, loaded your BIOS 1802 Settings and got the black screen.
- I've tried using the opencore sanity checker and modifying the config list based on what they recommended to change, same black screen.
- I've tried different arrangements of Bios settings for any differences in the loads but nothing has changed the outcome.
Any help would be greatly, greatly, greatly appreciated.
First of all, welcome to the forum. Some questions and suggestions:
- The modified BIOS 1802 is for the Asus X99 Deluxe II. It may not be prudent to force-install that on anything else. Nevertheless, if you have already done so, then:
- Are you able to enter BIOS Setup?
- In BIOS, does it say version 1802?
- If you have Windows or Linux on this system, do they work okay with the new BIOS?
- Because you're using an RX 5700 XT, do you have the boot-arg "agdpmod=pikera"?
- At what point exactly does the system get stuck with a black screen?
- Do you see the Apple Logo boot process with a progress bar below the Apple logo?
- Does the progress bar move at least half way across? And the black screen happens afterwards?
- Or does the black screen occur immediately after the Apple Logo appears?
- Or does the Apple Logo not even appear?
