Install on Mac

1. Mount EFI System Partition

diskutil mount disk_NUMBER 

To find out EFI partition disk number use diskutil list

The command is as follows in my case:

diskutil mount disk0s1

2. Copy OneFileLinux.EFI to EFI Partiotion

cp ~/Downloads/OneFileLinux.efi /Volumes/EFI

3. Set NVRAM to boot linux once

sudo bless --mount /Volumes/EFI --setBoot --nextonly --file /Volumes/EFI/OneFileLinux.efi

This command will boot linux only once. Next reboot will return previous boot sequence.

!!! Note that System Integrity Protection (SIP) prohibits to change boot options.
You can run bless from Recover Mode console. Press CMD+R while power on and go to "Utilities —> Terminal"

Install on PC

If your motherboard has UEFI Shell, just choose the path to OneFileLinux.efi on ESP.
Otherwise add new boot options to NVRAM and choose it from boot menu.

Example for ThinkPad x220

1. Copy OneFileLinux.efi to EFI Partition

2. Add NVRAM entry

efibootmgr --disk /dev/sda --part 2 --create --label "One File Linux" --loader /OneFileLinux.efi

3. Choose new entry from boot menu

Press F12 while power on and choose new boot entry
