Intel Mac OS X - .DMG and .HFS files

Version 1.62 Beta 2 and later only.
Tip: Use 7zip to examine the file contents.
If you have a bootable Intel Mac .dmg file containing a single uncompressed  HFS+ disk image (e.g. Niresh Hackintosh USB .dmg files), just add the .dmg file to your E2B USB drive and keep the file extension as .DMG (or .dmgPTN). ExampleNiresh OSX-Mavericks.dmg 5.26 GB (5,653,921,792 bytes).
If you have a bootable .dmg file containing a single compressed  HFS+ partition image (e.g. MBR+1.hfs), then use 7Zip to extract the single partition image file (e.g. 1.hfs) and add it to your E2B USB drive (it can be renamed and given a .hfs or .hfsptn file extension). Example: Niresh Yosemite-Zone_10.10.1.dmg 4.96 GB (5,332,012,208 bytes) - extract 1.hfs.
Note: If you get a boot1:/boot error under VBox, try booting from a real system!
.dmg files that contain more than one partition are not currently supported.
You can create a USB Flash drive using Windows TransMac (right-click on USB drive - Restore with Disk Image) and then if it contains a HFS single partition, make a partition image .HFSptn file using RMPrepUSB - Disk->File - Start=P1, End=P1, FileStart=0). However, the .dmg image must be bootable and most Apple .dmg Installers/Upgrades are not bootable.
You can use UniBeast under OS X to make a single-partition bootable Intel OS X Flash drive from a non-bootable Apple .dmg OS Installer file and extract the HFS partition image from that (see above for RMPrepUSB settings).
For more details see the blog entries here and here.
iPortable Snow x86 from E2B video with brief instructions in the Description here.
Niresh Catalina has not been tested (UEFI+GPT install required - MBR not supported). Suggest download Niresh .dmg and extract 3.hfs. Then follow 'MacOS High Sierra Installer' below.
Note: When you run a .dmg or .hfs file, it creates a new partition entry #4. This partition entry is used by E2B and so is normally unused/empty.
E2B will complain about it when you reboot to the E2B drive and it will ask if you want to delete it (if you don't delete it then the E2B menu will not load!).

If you regularly use .dmg and/or .hfs files, you can add a 'partnew' command line to the \_ISO\MyE2B.cfg file to delete the #4 partition every time E2B boots. See the Sample_MyE2B.cfg file for more details.


MacOS High Sierra Installer

Download the prepared clover.img and OSX_10.13.1_Installer.hfs from this article. I used the torrent download.

Install the MPI Tool Kit onto your Windows office system before you begin.

1. Drag-and-drop the clover.img file onto the MPI_FAT32 Desktop shortcut - name the file with a .imgPTN file extension - e.g. OSX_10_13_1_Installer.imgPTN

2. Copy the large .hfs file to the E2B USb drive (e.g. \_ISO\MAINMENU) - rename the file so it has no dots or file extension - e.g. OSX_10_13_1_Installer

3. Copy the OSX_10_13_1_Installer file to the same folder as the .imgPTN file

4. Run \MAKE_THIS_DRIVE_CONTIGUOUS (run as admin).cmd

5. Run \_ISO\SWITCH_E2B.exe and double-click on the OSX_10_13_1_Installer.imgPTN+OSX_10_13_1_Installer entry to switch it in.

If prompted for a partition type for the 2nd image file, use 0xAF.

6. Add this line to the large \menu.lst file on the E2B drive:

parttype (hd0,2) 0xAF

Note: You must always boot to the CSM menu first, so that this command is executed and the HFS partition is made visible or use SWITCH_E2B and specify 0xAF as the 2nd partition type.

7. Now UEFI-boot on a Mac or Macintosh x86 system (must have correct CPU and >4GB RAM).

You can also try the Clover boot option (MBR-booting).

Other .hfs files can be substituted to install different versions.

See RMPrepUSB Tutorial 144 for more details.

If you regularly use .dmg and/or .hfs files, you can add a 'partnew' command line to the \_ISO\MyE2B.cfg file to delete the #4 partition every time E2B boots. See the Sample_MyE2B.cfg file for more details.
