Estou com o mesmo Problema atualmente. Tentei todo tipo de procedimento e não deu certo. Estou aqui com um MacBook Pro 5,4 (Mid-2009) parado porque não está instalando nada, ele me veio com o SSD zerado também.

I ran the Clear Nvram command several times and it didn't work either.

Today I tried the High Sierra and Mojave image through patch and it didn't work either ://

I did the procedure to burn MacOS El Capitan and it didn't work, it got stuck on "PCI Configuration Begin" as shown in the images. I deleted the "EFI" folder but it didn't work either, it kept giving the same error: PCI Configuration Begin. EDIT: I used OpenCore Legacy Patcher and now the boot stops at this part

Hello! This is my first post here on the forum. I got a MacBook Pro Mid 2009 (MacBookPro5,4 - MAC-F22587A1), Core 2 Duo 2.53GHz, and I’m facing issues installing any macOS on it. Initially, it came with Windows 11 installed on the SSD. Audio, trackpad, and Wi-Fi (only Ethernet) didn’t work. I formatted it and installed Linux, Zorin OS Core, and saw that the trackpad was working normally. I opened the MacBook to check inside, and it doesn’t have a Wi-Fi card, has 4GB of DDR3 RAM (2x 2GB), and a 128GB Lexar SSD. I tried various macOS images, and the only one that works is macOS X Snow Leopard 10.6.3. When it updates to 10.6.8, it gets stuck at PCI Configuration Begin, and the only way to fix it is to reinstall the system via USB again. I’ve tried creating bootable versions of El Capitan, Sierra, High Sierra, using Open Core Legacy Patcher, High Sierra Patcher, Mojave Patcher from Dosdude, but none booted, or froze when I tried to proceed, or said the OS wasn’t compatible with the MacBook, or froze at PCI Configuration Begin or sometimes at "Legacy Shim 2". I know I can use Linux, but honestly, I’d like to try macOS on Apple hardware. I have a Hackintosh desktop that works great. If I can get a more usable macOS, I’m willing to expand RAM, SSD, and add a Wi-Fi card to this MacBook. I need help, everyone; take your time. Here are some photos of everything mentioned.
