Hi! When i try to install AlmaLinux on my old MacBook i get this error on the disk section of the installer: resource to create this format macefi is unavailable.
Hi, I believe this usually means the AlmaLinux installer is having trouble creating an EFI System Partition (ESP) using the macEFI format, which is specific to how Macs boot via EFI.
Since The macEFI partition format is Apple-specific, you probably need to get gparted on a USB device, and boot it up to completely wipe the drive so that partition is gone.
Then when you try your install, it should be able to create a new (Non Mac) EFI partition properly.
