Fixing Missing OpenCore EFI after NVRAM Reset
Resetting the NVRAM clears the 'bless' on the OpenCore partition. If you can't see the EFI Boot anymore, your Mac has reverted to its factory boot behavior.
How to Recover:
- Use the USB Installer: Plug in the OCLP USB you created. Hold Option on boot. The EFI Boot from the USB should appear. Select it, then select your internal macOS partition.
- Re-Bless the Drive: Once in macOS, open the OCLP app and click Build and Install OpenCore. Target your internal SSD. This will re-write the boot variables.
- Startup Disk: Go to System Settings > General > Startup Disk and select your macOS drive.
- Wired Keyboard: If the Option key isn't working, ensure you are using a Wired USB Keyboard. Wireless/Bluetooth keyboards often don't initialize early enough after an NVRAM reset.
