We do not support apple, sorry

Restart please.

Why do you think grub is not installed?

I don't really know, I'm new to Garuda and Arch based Operating Systems as a whole, I've rarely had Grub problems with Linux, and I'm not dual booting.

We have two parts
Unsupported hardware
Unsupported dual boot
= Unsupported hardware | Dual boot

You post from live ISO?
Do you reboot/restart your PC?
Do you see something like this?

Use Whoogle and search about your model and arch linux.


I am posting from live ISO

Macs are problematic with efibootmgr, that could be why your installation failed. I am assuming you did try installing and installation went fine until bootloader installation, follow this guide with 2 details:

  • You have UEFI system, don't do the "If the system is installed in Legacy BIOS/MBR
    Find your device that holds MBR and install grub" part
  • Add the --no-nvram --removable parameters to grub-install command
