Making a bootable High Sierra USB Installer Entirely From Scratch in Windows or Linux Mint (without access to Mac or App Store Installer.app)By fusion71au
Making a High Sierra USB Installer Entirely From Scratch in Windows
This is a proof of concept tutorial, to show it's possible to create a vanilla High Sierra installer, entirely from scratch, in Windows (even without App Store downloaded "Install macOS High Sierra.app" from a real Mac ). @PikeRAlpha's link to Apple's Software Catalog provides us with all the URLs necessary to download the needed files directly from Apple instead of some dubious source from the internet...
8GB or larger USB drive Boot Disk Utility v2.1.2017rev021b from @CVAD TransMac (free 15 day trial) Paragon Hard Disk Manager Free Download Installer Files Directly from Apple
1) Browse Apple's Regular Software Catalog and find the URLs to download the following 6 installer files...
BaseSystem.dmg BaseSystem.chunklist InstallInfo.plist InstallESDDmg.pkg AppleDiagnostics.dmg AppleDiagnostics.chunklist (Hint - search page for "InstallESD" to find its URL and others nearby)
to a folder named "SharedSupport" on your Windows NTFS drive. A browser download manager (eg Chrono for Chrome, dTA for FireFox) is handy since InstallESD is >4GB ---> allows you to pause/resume interrupted download...
2) Rename InstallESDDmg.pkg to InstallESD.dmg
3) Edit InstallInfo.plist with WordPad/text editor to remove the chunklistURL and chunklistid keys for InstallESD, and renaming it from InstallESDDmg.pkg to InstallESD.dmg (example of edited file attached to this post)...
Note: You can verify the SHA1 checksum of your InstallESD.dmg and BaseSystem.dmg with the correct ones at this website.
Boot Disk Utility to format the Installer USB and Restore OS X Base System HFS partition
1. Format USB with BDU & latest Clover ---> creates boot files in CLOVER partition + second FAT partition
2. Extract 4.hfs from \SharedSupport\BaseSystem.dmg with BDU --> save to it's local folder
3. Restore 4.hfs to USB second partition with BDU ---> 2nd partition becomes bootable "OS X Base System"
Paragon Hard Disk Manager to extend HFS Partition to its Full Extent
Open Paragon Partition Manager Free and resize the second partition of the USB drive to the full size allowed. Don't forget to apply the changes at the end...
Transmac to Copy "SharedSupport" folder to OS X Base System
1. Open the TransMac program and navigate to the HFS+ Volume/Install macOS High Sierra.app/Contents folder. Right click anywhere in the empty space on the RHS pane and select "Copy Here"...
2. In the next stage, select the "SharedSupport" folder we created above as the "Files and Folders to be copied to the Mac Volume"...
Clover configuration is required now. The default config.plist (in the Clover FAT32 partition of the USB) maybe sufficient to boot your machine if you’re lucky. If not, look at the Clover Wiki, Clover Instructions and Clover Configuration Thread for pointers and edit /EFI/Clover/config.plist accordingly with Wordpad or Notepad.
The location of the important configuration files for Clover are summarized below
config.plist--->EFI/CLOVER folder DSDT.aml with or without SSDT.aml--->EFI/CLOVER/ACPI/patched (don't need one if your DSDT is auto patched by Clover in config.plist) Kexts eg FakeSMC, NullCPUPowerManagement --->EFI/CLOVER/kexts/<osx version> or /Other. NB BootDiskUtility by default already has FakeSMC.kext installed here. You may need to add VoodooPS2Controller for your laptop keyboard/trackpad to work. If UEFI booting, you will most likely need one of the OsxAptioFixDrv-64 drivers copied from /EFI/CLOVER/drivers-off/drivers64UEFI to /EFI/CLOVER/drivers64UEFI. If you want to use the installer to run High Sierra in Windows on VMware, you can follow my guide to set up the Virtual Machine and replace Clover's default config with EFI_Clover for VMware (which is compatible to run in VMware). In the screenshots below, I have attached the USB Installer (in this case PhysicalDrive7) to my macOS Virtual Machine. Reboot the system to the USB installer to install High Sierra ...
What happens if we don't have access to TransMac or Paragon Hard Disk Manager?
Not a problem, as long as we get "OS X Base System" bootable, we can launch terminal from the Utilities Menu to copy the SharedSupport folder over to the Installer app. In essence, we will build the full installer app = 5GB+ on the target HD eg "Macintosh HD", by copying both the "small" installer app = 15MB (on "OS X Base System") and the SharedSupport folder from the NTFS volume (mounted in this example on /Volumes/DATA)...
-bash-3.2# cd / -bash-3.2# cp -R Install\ macOS\ High\ Sierra.app /Volumes/Macintosh\ HD/ -bash-3.2# cp -R /Volumes/DATA/SharedSupport /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app/Contents/
...then start installation with the startosinstall utility...
-bash-3.2# /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --volume /Volumes/Macintosh\ HD --converttoapfs NO --applicationpath /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app
The above steps can be automated with the attached "startosinstall.command" script, which will assemble "Install macOS High Sierra.app" on "Macintosh HD" and launch the startosinstall utility targeting the "Macintosh HD" volume. Copy/download to "Macintosh HD", then run in terminal (after attaching DATA USB with /Shared Support folder)...
cd "/Volumes/Macintosh HD" chmod +x startosinstall.command ./startosinstall.command Updated Download Links for macOS Mojave 10.14.2_18C54
Browse Apple's Regular Software Catalog and find the URLs to download the following 6 installer files...
BaseSystem.dmg BaseSystem.chunklist InstallInfo.plist InstallESDDmg.pkg AppleDiagnostics.dmg AppleDiagnostics.chunklist
Note: In Mojave, Apple has removed the --converttoapfs NO and --applicationpath arguments from the startosinstall utility....
eg to use startosinstall for the above section "What happens if we don't have access to TransMac or Paragon Hard Disk Manager?", the syntax is now
-bash-3.2# /Volumes/Macintosh\ HD/Install\ macOS\ Mojave.app/Contents/Resources/startosinstall --volume /Volumes/Macintosh\ HD
This basically means that for Mojave, the default installation will always convert the target volume to the apfs file system.
First time trying an hackintosh, and I've been stuck like this for days now, nothing I try seems to have any effect. I can't even get the installer to launch..
Intel i7 8700K Gigabyte Aorus Z370 Ultra Gaming 2.0-OP Gigabyte Aorus Radeon RX570 4G Corsair Vengeance LPX 32GB (2x 16GB) Samsung 970 Evo 500GB be quiet! Silent Base 600 be quiet! Dark Rock Pro 4 be quiet! Dark Power Pro 11 550W I've tried creating an install USB using this vanilla guide: https://hackintosh.gitbook.io/-r-hackintosh-vanilla-desktop-guide/
I seem to get to about 50% loading the installer. Then it will get kernel panic.
Trying with macos 10.14.2.
Here's a video of what happens: https://nizzlay.stackstorage.com/s/4r71CXWCenNCgX9
Any advice would be greatly appreciated!
Hi guys, this thread is to show you a new and open source app, created by me, that I called TINU:
The name means: TINU Is Not #####, the U refers to a popular software that is used to create macOS hackintosh installers (that for good reasons is banned on this forum), but the aim of the name is to explain that this app is a totally different thing from that software and works in a totally different way.
This app basically is a graphical interface for the createinstallmedia executable that is inside the macOS and Mac OS X installer apps, it is capable to create a bootable installer completely vanilla like what you do using the command line method, and also this method is recommended by apple itself. In addition to this, this app provvides to you simplicity and flexybility, and lets you to avoid most of the steps needed with every other app.
TINU allows you to create easily a bootable macOS installer without messing around with command line stuff and without using disk utility, all you need to do is use the app and then install clover on the usb drive once TINU has finished or leave it as is if you want to use it on a real Mac.
- Simple-to-use UI that allows you to easily start the bootable macOS installer creation process.
- It can work with every macOS installer app that has the createinstallmedia executable inside its resources folder (including also beta and newly released installers).
- You can use any erasable volume that is at least 7 GB of size (if the volume's drive is not in GUID format, TINU will re-format it accordingly).
- Can work with the Mac OS recovery system, so you can create a bootable macOS installer from the macOS installer itself or from the macOS recovery partition, and you can use TINU to install macOS, too.
- 100% clean: The bootable macOS installers created with this tool are vanilla, just as if you created them using the command line "createinstallmedia" method in Terminal.
- Open Source: You can verify what this program does on your computer and you can create your own version by downloading and playing with the source code.
- Does not require any special preparations. Just open the program, make sure you have a USB drive plugged in and have a macOS installer app on your disk.
- No need to use Disk Utility. TINU can format your drive or partition for you.
- Integrated EFI partition mounter tool.
- Uses recent, modern, APIs and SDKs and the Swift 3 language.
- Transparent graphics style available (type alt-S or choose from the menu bar: View -> Use transparent style).
- Works using the latest versions of macOS and will also support newer Mac installers out of the box without requiring an update.
- Offers advanced features to customize your bootable macOS installer.
Features that are planned for future versions:
- Install and configure [Clover](https://sourceforge.net/projects/cloverefiboot/).
- Install kexts into Clover's kexts folder.
- Clover drivers customization
- Use custom DSDT in Clover
- Integrated pre-made Clover config templates database from a remote and open repository.
- Support for other languages, at least Italian.
- A computer that runs Mac OS X Yosemite or a more recent version (Mac OS X El Capitan is required to use TINU in a macOS recovery or installer).
- A drive or a free partition (on a drive which already supports GUID) of least 7 GB that you want to turn into a macOS/Mac OS X installer.
- A copy of a macOS/Mac OS X installer app (Maveriks or newer versions are supported) in the /Applications folder or in the root of any storage drive on your machine (excepted the drive or volume you want to turn into your macOS install media).
