Describe the bug
A clear and concise description of what the bug is.
I can't get passed the grub menu when booting into the USB. I get to the grub screen and can choose to boot from open source or proprietary drivers, can select time zone, etc., but when I finally choose to reboot, it will just boot back into MacOS.

To Reproduce
Steps to reproduce the behavior:

1. Flash .iso to USB using Etcher
2. Turn off secure boot
3. Restart computer and select the EFI drive to boot from
4. Select either boot with proprietary drivers or open source drivers
5. It will always boot back into MacOS, even if I try to set the time zone

[bojohnson5]

I don't see any option for Boot x86 64 {Your Edition} in the grub menu. I've set the time zone but that didn't fix anything.

Do the fans go up for a few seconds before it reboots? If so, it's probably a T2 panic. Try setting intel_iommu=on acpi_osi=linux efi=noruntime for GRUB params (hit e over the one you want to boot from).

[bojohnson5]

There is no fans spinning up before the reboot. I did add those grub params before booting, but still didn't get anywhere. Could it be that I'm trying to boot into a USB 2.0 device from a dongle? I should also mention there are no EFI bootloader files found when I select that option. Is that due to the particular .iso I've downloaded?

I would suggest you to move to EndevourOS.
