Will M1 and Apple Silicon Macs Support OCLP When They Become Unsupported?

Blogger Info: OpenCore Legacy Patcher for Apple Silicon (M1/M2/M3) Macs

Users are asking whether Apple Silicon (M1) Macs can run future macOS versions via OCLP or boot exploits once Apple drops official support. Here is a breakdown of the technical feasibility:

1. How OCLP Works on Intel vs. Apple Silicon

OCLP exploits the customizable nature of UEFI bootloaders on Intel Macs. Apple Silicon (M1/M2/M3) Macs do not use UEFI/BIOS; they use a completely proprietary boot chain (Secure Boot, LLB, iBoot). This makes standard UEFI-based injection methods impossible.

2. Technical Possibilities for Future Support

• Permissive Security Policy: Apple Silicon Macs natively allow users to lower security settings and boot custom kernels (which is how projects like Asahi Linux boot). This means that modifying system files (similar to root patching) is officially supported by Apple's hardware policies.
• Kernel & Driver Matching: The main challenge will be injecting drivers for older Apple Silicon GPUs or Wi-Fi cards into newer macOS kernels. Since Apple Silicon uses a unified architecture, the community will need to build kexts and firmware wrappers once Apple officially cuts support for the 2020 M1 models.

Conclusion: While it will not be "OpenCore" in the traditional Intel sense, the security model of Apple Silicon *does* allow custom OS loading, meaning custom patchers are highly likely to appear when the M1 becomes legacy.
