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
You can install as many OSes as you want.
Odds are your Linux install overwrote OCLP. You’d need to install OCLP again and configure it to boot from either Mac OS or your Linux install.
And with GPT partition you can have 128 partitions so ~120 different OSes easily on a single drive.
Even more with btrfs or LVM.
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.
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.
You can always chainload bootloaders and have grub or refind pick the linux os
OP is using OpenCore Legacy Patcher to run an newer OS on an unsupported machine. The option boot menu won’t work, they’d need to get back to the OCLP menu to boot Mac OS.
If they all support EFI, you’ll be out of disk space before you hit the limits of EFI partitioning.
Unless you’re one if those challenge accepted people who will try installing 10,000 floppy drive-sized microlinuxes on one system.
We’re assuming useful daily driver desktop as the benchmark here. Not boot to a console with nothing on it.
Did you choose the right partition?
Do you still see your Mac partition when you do
fdisk -l
?
