Fixing Missing Graphics Patches on iMac 2012 in macOS Sequoia

Older metal GPUs, such as the NVIDIA Kepler GT 640M/650M in the 2012 iMac, require specific patches under OCLP to enable graphics acceleration in macOS Sequoia.

How to Resolve the Issue:

  1. Update OCLP: Download the latest nightly or public release of OpenCore Legacy Patcher that explicitly supports macOS Sequoia Kepler patching.
  2. Check SIP Status: Open Terminal and type csrutil status. SIP must be disabled. If it is enabled, boot into Recovery Mode, open Terminal, and run csrutil disable.
  3. Boot Args: Ensure you have the correct boot args in your config. OCLP requires AMFI adjustments, typically handled by OCLP automatically, or by adding amfi=0x80 if using custom setups.
  4. Re-Run Patches: Open OCLP, click Post-Install Root Patch, and click Start Root Patching to re-apply the graphics drivers.

Original Question: "Have a iMac 2012 year (13,1) graphic patch on MacOS Sequoia?"

I have just installed macOS 15 Sequoia on my 2012 Mac, but in OpenCore I only see the internet patch and no graphics patch. Does a graphics patch even exist for this Mac model? (btw, everything works fine on macOS Sonoma and all patches are available there.)
