Dual Boot Linux Mint 21.2 and macOS with OpenCore Legacy Patcher and OpenCore Bootpicker

Update: No luck. Tried several things:
- Installing mint via "ubiquity -b" ergo without boot loader => no luck

- In Linux "sudo systemctl disable systemd-boot-check-no-act.service" => failed.. does not exist, since I got no boot loader

- In Linux "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor nvram_modify_on_write=0"" was a suggestion, together with "sudo apt purge os-prober -y" and "sudo update-grub" => All yielded the same result.

- In macOS "sudo bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/OC/OpenCore.efi" gave me an error: "could not set boot device property: 0xe00002e2"

- Also tried in Linux "sudo apt remove efibootmgr -y", and blacklisting efi changes via "echo "blacklist efivarfs" | sudo tee /etc/modprobe.d/blacklist-nvram.conf" and "sudo update-initramfs -u"

Now Gemini suggest to place an additional boot loader IN FRONT of OCLP... I don't know... that doesn't seem right.

I had lost all hope on attempting to get a dual boot to work until I came across your comments. I have endeavorOS(arch based) installed and blacklist efivars worked for me to not have to reinstall opencore after every linux boot. I cant imagine what else you could do. Are you using the ext4 driver in opencore or another boot manager to boot linux.
