Resolving Boot Manager Conflicts in Triple-Boot Setups
If rEFInd shows a black screen when a USB is inserted after installing OpenCore, it's a conflict in the UEFI GOP (Graphics Output Protocol) initialization.
The Fix:
- Config.plist Edit: In your OpenCore config, go to
UEFI > Outputand setProvideConsoleGopto False. rEFInd often tries to initialize its own console GOP, and having OpenCore do it simultaneously causes the black screen. - DirectGopRendering: Set this to False as well.
- rEFInd Config: Ensure
scan_delayis set to at least 1 or 2 seconds in yourrefind.confto allow the USB drive to initialize before the menu renders.
Original Question: "(Suspected) OpenCore Preventing rEFInd from Booting When USB is Plugged in"
I have a triple-boot setup on my late 2013 MacBook Pro (Arch Linux, macOS Sequoia (via OCLP) and Kali Linux). I use rEFInd as my boot manager. (rEFInd -> OC -> macOS/ rEFInd -> GRUB -> Linux) Before I installed macOS/OpenCore, my rEFInd menu worked just fine when booted with a USB inserted but now it's just a black screen. GRUB and OC works when booted via boot priority but when rEFInd is the boot priority it is just a black screen. Could this be a setting in my config.plist? Again, this worked before OpenCore/macOS was installed. Cleared NVRAM, tinkered with some settings but still nothing.

Thanks lots.
