Problem on a Mac Mini Mid 2011. I have looked through other articles and couldn't get help. Any help?
Add the grub arguments
noapic noacpi nosplash in place of
noacpi are kernel boot options. ACPI stands for Advanced Configuration and Power Interface and APIC stands for Advanced Programmable Interrupt Controller.
Immediately after the motherboard / computer manufacturer logo splash screen appears when the computer is booting, with BIOS, quickly press and hold the Shift key, which will bring up a GNU GRUB menu screen. With UEFI press (perhaps several times) the Esc key to get to the GNU GRUB menu screen. Sometimes the manufacturer's splash screen is a part of the Windows bootloader, so when you power up the machine it goes straight to the GNU GRUB menu screen, and then pressing Shift is unnecessary.
You will see a GNU GRUB menu screen that looks like this:
Press e to enter editing mode. This will bring up a GNU GRUB screen that looks like this:
Use the arrow keys to navigate when screen editing the above screen. Navigate to after the string on this screen that starts with
root=. In this example screen the full string is
root= followed by
UUID= and a hexadecimal string as shown below:
Immediately after this string replace
quiet splash by
noapic noacpi nosplash. This change is only temporary — it will just be used once and GRUB won't remember it in the future. It may be possible to make these changes permanent by changing the ACPI and APIC settings in the Mac Mini's UEFI firmware. Press Ctrl+X or F10 to boot with the kernel boot options that were added. If you make a mistake, press Esc to go back to the previous screen.
