Preparing your installer media

After the download, you'll find a new folder named macOS downloads
where the program we used downloaded macOS recovery image for your macOS version. For this part of the setup. I'll be separating it to the 3 main OSes and how to make it.
Thanks to /u/corpnewt's time and head-butting, he made a pretty good script to make the installer on the USB.
There is an issue with the latest Clover releases where the network kexts dont get injected into macOS Recovery/Installer environments. The latest known good Clover that did inject them properly is r5092. Please use this release then update it afterwards.
Some users have reported r5103 had this issue fixed.
Inside the same folder of gibMacOS, you'll find a cute MakeInstall.bat
, double click it, accept UAC admin user, you'll be greeted by a CMD screen. The software will download software needed (dd
port for windows and 7-zip). Then you'll be greeted with a list of drives:
Carefully choose your drive (look for the size, name or other features that points to your USB device).
type in its number
press enter and follow the rest of the instructions
You'll be asked to drop the Recovery image path, go to macOS downloads
and explore its folders, until you get to a file with .pkg
in the end, named either RecoveryHDMetaDmg
or RecoveryHDUpdate
(depending on your macOS version).
Drag-n-Drop will not work, so the workaround is Shift
+ Right click on the file, then select Copy as Path
as shown here
Note: you can just paste the path of the parent folder of the pkg file (found in macOS downloads
> publicrelease
(if you used another channel, go to that channel) <your macOS version folder>
) and the script will look for the pkg.
then paste it in the CMD window (by Right Clicking in the window, this will paste what's in the clip board)
the program will then:
extract and restore to the USB the recovery downloaded earlier
download and install clover (unconfigured) to the USB
install legacy boot sectors for Legacy users (wont affect UEFI users)
You may continue go to the next section of this guide...
This section will target making the necessary partitions in the USB device. You can use your favorite program be it gdisk
fdisk
parted
gparted
or gnome-disks
. I will focus on gdisk
as it's nice ¯\(ツ)\/¯ and can change the partition type later on, as we need it so that macOS Recovery HD can boot. [the distro used here is Ubuntu 18.04, other versions or distros may work]
In terminal:
run lsblk
and determine your USB device block
run sudo gdisk /dev/<your USB block>
send p
to print your block's partitions (and verify it's the one needed)
send o
to clear the partition table and make a new GPT one
confirm with y
send n
partition number: keep blank for default
first sector: keep blank for default
last sector: +200M
to create a 200MB partition that will be named later on CLOVER
Hex code or GUID: 0700
for Microsoft basic data partition type
send n
partition number: keep blank for default
first sector: keep blank for default
last sector: keep black for default (or you can make it +3G
if you want to partition further the rest of the USB)
Hex code or GUID: af00
for Apple HFS/HFS+ partition type
send w
Confirm with y
Close gdisk
by sending q
Use lsblk
again to determine the 200MB drive and the other partition
run mkfs.vfat -F 32 -n "CLOVER" /dev/<your 200MB partition block>
to format the 200MB partition to FAT32, named CLOVER
then cd
to macOS downloads
and keep going until you get to a pkg
file
download p7zip-full
(depending on your distro tools)
for ubuntu/ubuntu-based run sudo apt install p7zip-full
for arch/arch-based run sudo pacman -S p7zip
for the rest of you, you should know ¯\(ツ)\/¯
run this 7z e -txar *.pkg *.dmg; 7z e *.dmg */Base*; 7z e -tdmg Base*.dmg *.hfs
this will extract the recovery from the pkg through extracting the recovery update package then extracting the recovery dmg then the hfs image from it.
then when you get 4.hfs
or 3.hfs
(depending on the macOS version used) run dd if=*.hfs of=/dev/<your USB's second partition block> bs=8M --progress
(you may change the input file if
and the block size to match your needs
after that, you're ready to go for the next step of the guide...
After the download, open macOS downloads/.../...
until you find RecoveryHDUpdate.pkg or RecoveryHDMetaDmg.pkg (enable file name extensions in Finder under Finder > Preferences > Advanced).
locate the pkg
do not open it
rename the extension from .pkg
to .dmg
open the image (it will be mounted)
find Basesystem.dmg
double click to mount it
open Disk Utility
application (Launchpad > Other >)
Select View > Show All devices (above the drive list)
Select your USB device (not the partition)
Select Partition
if you do not see partition:
Select Erase
Name: whatever Format: MacOS Extended Journaled Scheme: GUID Partition Table
Make:
a minimum of 200MB partition Name: CLOVER Format: MSDOS
the rest Name: whatever you want Format: MacOS Extended Journaled
Apply
Select the MacOS Extended Journaled partition
Select Restore
Choose BaseSystem from the list (it should be the image you mounted earlier)
Let it restore
When done you can continue this guide...
