Good idea to try .contentVisibility.Hi @CaseySJ,
Hi All,
I recently installed macOS Monterey on a new nvme M.2 drive to replace an existing drive (Samsung 970 EVO - now moved to a PCIe x4 expansion card) using Opencore 0.8.3 (using the EFI folder You Provide in the Opencore 0.8.3 Mini-Guide-thanks ) as boot manager in a multiboot system with different operating systems each on its own drive (nvme M.2, SATA SSD, SATA mechanical hard disks).
At startup, however, an "EFI" entry appears in the Opencore boot menu that doesn't seem to refer to any OS and that I can't delete.
I tried to identify which Drive or OS this menu entry refers to also using the ScanPolicy variable to exclude all SATA drives at startup but the "EFI" entry remains in the boot picker.
I learned in another thread that starting from Opencore 0.8.8 it is possible to add a .contentVisibility file in the /EFI/boot directory to hide/disable unwanted Opencore menu entries.
I noticed that in a previous post of this thread
You updated the EFI folder to version 0.8.8: can this be used for the Gigabyte Z390 Divisare motherboard or was it a custom solution for a specific User?[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580
Technically, the OpenCore EFI folder can be installed in any EFI partition. We just need to boot the OpenCore EFI so that the OpenCore Boot Picker appears. So it's not strictly necessary to copy that folder to EFI partition of USB flash disk, but I typically do that because it allows me to...www.tonymacx86.com
Any other suggestions are welcome
Thanks in advance for Your help
We can upgrade to latest OpenCore by using HackinDROM App as described in the spoiler at the top of Post 1 labeled Quick Reference to Mini-Guides and Micro-Guides:
