Fixing Missing Installer in OpenCore Picker

If your macOS installer volume doesn't show up in the OpenCore picker, it's usually due to a scan policy restriction or an incomplete USB creation.

Troubleshooting Steps:

  1. ScanPolicy: Ensure ScanPolicy is set to 0 in your config.plist (OCLP does this by default, but verify in Settings).
  2. Bless the Volume: If you created the USB manually, you may need to run sudo bless --folder /Volumes/Installer/System/Library/CoreServices --file /Volumes/Installer/System/Library/CoreServices/boot.efi in Terminal.
  3. Recreate USB: Use the Create macOS Installer option within the OCLP app itself to ensure the correct partition structure.
  4. USB Port: Try a USB 2.0 port or a different flash drive brand, as some USB 3.0 drives have compatibility issues with older iMacs during boot.

Original Question: "Open Core Picker never displays Installer"

I have an iMac14,2, Catalina, OCLP 2.4.1, SanDisk Ultra 32GB, GUID partition map, EFI present with OC folder, ScanPolicy 0, BOOTx64.efi manually added, installer volume is HFS+ Mac OS Extended, but it never appears in OpenCore picker.

Have tried everything I can think of. Was going to log as an issue on OCLP GitHub to see if there’s any know issue, but won’t let me post
