Setup:
OpenCore 1.0.2 (or whatever your version is)
Theme: Acidanthera/GoldenGate
Multi-boot: macOS + CachyOS + OmarchyOS (both Linux distros using UKI boot)
PickerMode: External
PickerAttributes: 145
PickerVariant: Acidanthera/GoldenGate
Problem: Custom icons for my Linux boot entries won't display - they show generic drive icons instead. macOS entries show correct custom icons.
Boot entries detected by OpenCore:
"CachyOS" → /EFI/CachyOS/cachyos_latest.efi (on separate EFI partition)
"OmarchyOS" → /EFI/Omarchy/omarchy_latest.efi (on separate EFI partition)
What I've tried:
Created icons in /EFI/OC/Resources/Image/Acidanthera/GoldenGate/ with multiple naming variations:
CachyOS.icns, cachyos.icns, cachyos_latest.icns, CachyOS (UKI latest).icns
OmarchyOS.icns, omarchy.icns, omarchy_latest.icns, omarchy_fallback.icns
Linux.icns (as fallback)
Verified .contentFlavour file exists in GoldenGate folder (it was missing - I created it)
Placed .icns files next to the actual bootloaders:
/EFI/CachyOS/cachyos_latest.efi.icns
/EFI/Omarchy/omarchy_latest.efi.icns
Verified EFI partition volume labels match icon names (CachyOS, OmarchyOS)
All icon files are valid Mac OS X icon format (verified with file command)
Still showing generic drive icons for both Linux entries after all this.
Has anyone successfully gotten custom icons working for UKI-based Linux boot entries? Is there something specific about UKI entries that prevents custom icon matching? Any config.plist settings I'm missing?
