I'm experimenting with a 2014 macbook pro upgraded to macOS 14.4 (Sonoma) with OpenCore Legacy Patcher, Linux Mint 21.3 Virginia and Linux Mint 21.3 Xfce.

First, I installed Linux Mint 21.3 Virginia and I could boot both to macOS and Mint. Then, I created another partition and installed Mint Xfce on it.

Now, I can only access both linux operative systems and macOS has disappeared.

What I don't understand is why now the notebook boots directly to grub instead of booting to OpenCore Legacy Patcher

    Yes. It mostly comes down to two things: Bootloader and partitioning schema.

    A properly configured bootloader should include an option for all of your OSes. In most cases, any installed OS should be autodetected an added to the menu. If not, as long as you can boot at least one linux distro, adding any missing ones isn't that hard. I suspect that in your case, the latest OS install didn't account for the missing OS during grub setup.

    Partitioning schema isn't hard either, but it can be a bit hard to keep track of the various partitions during install. Just make sure that each OS gets its own partition(s), and that you don't mistakenly overwrite any during install.

    OSX doesn't seem to play nice with linux dual booting. I think holding the option key while booting should force the apple boot menu to show, at least it did when i tried.

    Probably when you installed the second linux you overwrote the boot loader instead of adding a new UEFI entry point.

    But I've never had a Mac, so take this with a pinch of salt, and honestly considering things can change based on what, in which order, and how you installed things.. it could be something else.

    you've got a grub bootloader in the efi partition. the computer is booting the efi partition's grub straight out of the gate. it doesn't know about the macos so it can't boot to it.

    you can edit the grub config to put an option in to boot to macos from grub but you can also just use option-boot to select partitions when you power the computer on.

    option-boot is when you hold the option key when you turn the computer on.
