I’ve been trying to get the latest version of Rocky installed on a partition of my Macbook Pro but I’m getting an error when I have the installer run automatically for the hard drive installation. See the attachment but it basically just says “resource to create this format macefi is unavailable”.
I also get this error when I try to install Centos 8.4.
I’ve faced the same issue while installing Rocky Linux in an iMac from 2008. The good news is that I have a working system!
Since I’m far from an expert, there may be steps that are not necessary or even incorrect, in any case here are the steps I followed. At the end I added some links to some sources I used to get this all to work:
- Boot into the install media and set it all up as desired.
- For the partitioning:
- Tell the tool to “Do not install boot loader”
- Select custom partitioning scheme:
/boot partition (1024 MiB, Standard, XFS), then edit it to make it
/boot/efi (1024 MiB, Standard, EFI Partition). I did this because the installer wouldn’t let me choose the right settings from the
+ menu and I wanted to follow the steps from (1) in order.
/boot partition (1024 MiB, Standard, XFS)
/home, in my case (X GiB, LVM, XFS) group
/ in my case (X GiB, LVM, XFS) group
/swap, in my ase (7.88 GiB, LVM, swap) group
- Proceed despite the warning/error regarding
mactel tell it to continue despite it all.
- Proceed with the installation.
- Boot into the newly installed Rocky. It should take you to GRUB2, but fail to load automatically.
- Boot manually:
- Identify the root partition, in my case:
- Point to the linux image:
linux (hd6,gpt4)/boot/vmlinuz-4.18... root=/dev/mapper/rl-root
- Note. For this step and the following I don’t remember exactly the versions of vmlinuz and initrd, nor the exact path. I used
ls, as in
ls (hd6/gpt4)/ to determine in which partition and path where vmlinuz and initrd.
- This should boot your Rocky.
- Once in the OS, update the GRUB configuration:
grub2-mkgconfig -o /boot/efi/EFI/rocky/grub.cfg
- Hopefully, you are all set. Reboot to verify.

- Using the GRUB2 boot prompt
