Apple’s installer checks your Mac’s board ID, model identifier, and T2 chip presence. If your Mac isn’t on the “official” list, the installer refuses to run. A patched ISO bypasses these checks, injecting drivers and kernel extensions (kexts) for older Wi-Fi chips, graphics cards, and USB controllers.
To get running on an unsupported Mac or in a virtual machine, you typically need to create your own "patched" installer or ISO. Apple does not provide official "patched" ISOs, so using tools like OpenCore Legacy Patcher (OCLP) is the standard, safest method. 🛠️ Recommended Method: OpenCore Legacy Patcher

The utility will pull the package directly from Apple’s servers and automatically assemble the installer file inside your /Applications folder. Step 2: Create a Standard macOS Sequoia ISO
Avoid downloading pre-patched ISO files from untrusted sources. These files frequently contain embedded keyloggers, remote access trojans (RATs), or modified system binaries that compromise your personal data, Apple ID security, and local network privacy. Always build your ISO manually using official Apple binaries and open-source patchers like OpenCore.
