Step 2: Right click the “Install OS X Mavericks.app” or “Install OS X Yosemite.app” you got from Appstore, click Show Package Contents, open Contents, open SharedSupport, double click “InstallESD.dmg” to mount the image file.

Step 3: Mount the hidden “BaseSystem.dmg” with this command using Terminal:

The image will be mounted as “OS X Base System”

Step 4: Pick the “Restore” tab in Disk Utility, drag and drop the “OS X Base System” to “Source”, drag and drop the  installer partition you create earlier to “Destination”, hit “Restore”

Step 5a (Mavericks): After the process is done, go to your USB’s “OS X Base System” partition ( don’t mistake the partition here, you can highlight and press Spacebar to check the size of the partition ), go to System/Installation and delete the alias “Packages”, then go to “OS X Install ESD” partition, copy the “Packages” to the folder System/Installation of you USB

Download Pacifist. Go to the folder System/Installation/Packages of your USB, right click the BaseSystemBinaries.pkg and Open With Pacifist. After Pacifist has done loading the file, locate “mach_kernel”, drag and drop it to the root of your USB’s installer partition.

Step 5b (Yosemite): Change the USB name to “Yosemite”, open terminal and type these command:

For Yosemite

Step 1: You need a 8GB USB stick, format it with Disk Utility with the following options:

  • Partition: 2 partitions
  • Partition 1: name it Clover, Format MS-DOS (FAT), size larger than 300MB
  • Partition 2: name it MacUSB, Format Mac OS Extended ( Journaled ), size larger than 6.5GB

Step 2: Download this Clover.zip, unzip and copy the EFI folder to the root of the CLOVER partition. Use Hackintosh Vietnam Tool to create the suitable config.plist for your PC:
– CPU: Select your CPU
– Graphics: Select your graphics
– SSDT: Generate

– Bootflag: kext-dev-mode=1
Install to current HDD, then copy the generated config.plist on the desktop IN YOUR HDD to the folder EFIClover of the CLOVER partition.

At this point you have 2 choices of creating the installer

Choice 1 (easy guide, but can result in blank screen after boot)

Step 3: Download OS X Yosemite from the Appstore, check if the “Install OS X Yosemite.app” is in the folder Application. Open Terminal and run this command ( note that Untitled is a HFS+ partition )

Choice 2 (manual method)

Step 3: – Right click to Yosemite Install app > Show Package Contents > Contents > Shared Support, open InstallESD.dmg.
– Open OS X Install ESD partition, open BaseSystem.dmg (hidden file)
– Use Disk Utility to clone OS X Base System to MacUSB partition.
