OS X 10.8 Mountain Lion bootable USB (without MAC)

Download the raw file from here.

How to use:

1 - Copy the .raw file to an USB stick using SUSE Studio Image Writer.

If you have error during copy, eject and re-connect the pen drive. When Windows asks if you want to format it, cancel and run Image Writer again.

If the problem persists, disable your anti-virus software, it may be blocking raw write to the drive.

Another Image Writer for Windows, if SUSE doesn't work

2 - Boot the USB drive and install.

If you need, type boot options, for example:
-v (verbose boot) [default]
-x (safe)
-s (single user)
GraphicsEnabler=yes (enable graphics card drivers) [default]
USBBusFix=yes (fix problems with USB devices)
npci=0x2000 (use if boot stops at "PCI configuration begin")
cpus=1

If you need, use TransMac to remove kexts which are causing problems (System/Library/Extensions) and use the flag -f (ignore caches) at boot, or remove /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext

If you get KP related to ApplePolicyControl.kext remove /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/ApplePolicyControl.kext

If boot stops right before reaching the installer, or graphics aren't working right, remove video kexts and boot with GraphicsEnabler=No -f

ATI = ATI*
Intel = AppleIntelHD* AppleIntelSNB*
nVidia = GeForce* NVDA*

You need at least one free partition, use Disk Utility (in the Utilities menu) to erase it as Mac Os Extended (Journaled).

If you want to install Chameleon (the boot loader) in this partition and you use MBR (not GUID, like if you already have Windows in the HD), it must be a primary (not extended/logical) partition.

Wait for the installation to finish and restart.


3 - Boot the USB drive, then choose to boot the HD you just installed OS X (not the installer USB again).


4 - Install Chameleon and the Extra folder to the HD.

I recommend using Chameleon Wizard to install and create/configure org.chameleon.Boot.plist and SMBIOS.plist in /Extra folder.

5 - Install essential and other kexts you may need (network, audio, etc).

FakeSMC.kext is always needed.

While you don't have power management fixed, you will probably need NullCPUPowerManagement.kext.

If you use PS/2 keyboard or a laptop you will need VoodooPS2Controller.kext (or ApplePS2Controller.kext) and AppleACPIPS2Nub.kext.

I recommend using Kext Wizard to install kexts.

  1. I copied raw file into a 8 GB USB drive without any problem using SUSE Studio Image Writer (Now it's not opening on windows). But I can't boot from USB on my Lenovo G580 Laptop. I tried disabling UEFI mode in BIOS, but Unfortunately there is no option to disable secure boot. Is there is anyway to fix this problem?

    1. To disable secure boot, first set Administrator password. Now you can disable the secure boot in the same menu. Change UEFI to Legacy mode. I hope it works.

    2. I set administrative password, But secure boot option is not available in my BIOS. UEFI is already in legacy mode. The usb is working on other computers.

    3. It is to be in the same menu as of admin password

  2. Thanks for the guide, but when I've got the image on the USB, my laptop wont recognize anything on it. It's got an Intel i7 3630QM and 8GB of ram, so shouldn't be any problems here..

    1. Sorry for late reply.
      Did you figured it out?
      Is the USB booting?

Ubuntu: Access a usb flash drive from the terminal

    1. Find what the drive is called You'll need to know what the drive is called to mount it. To do that fire off: sudo fdisk -l You're looking for a partition that should look something like:   /dev/sdb1 . Remember what it's called. 2. Create a mount point Create a new directory in   /media   so you can mount the drive onto the filesystem: sudo mkdir /media/usb 3. Mount! sudo mount /dev/sdb1 /media/usb When you're done, just fire off: sudo umount /media/usb Source: StackOverflow

Karabiner: Mouse/keyboard customizer for OS X

For beginners, or the one who migrated from Windows environment, Natural Gestures (Scrolling and Swiping) might be bit confusing. But, once you get familiarized with them, it may feel like "What was I doing, all those days?". It all changed, when I connected external mouse to my Macbook. When you start using that WHEEL, you will be confused. Luckily there is a setting for mouse, to change scroll behavior (natural or the other way). But, here's the catch. If you toggle that setting, it also toggles the same for TRACKPAD!!!!! I've seen that many people were freaked out and even raised BUG report to Apple. But, all those reports were closed, saying that is not a bug, but intentional feature!!! For those, who can't leave with such one-sided settings, here is a simple util, which came to my rescue: Karabiner It's simple, powerful and stable mouse/keyboard customizer for OSX. Without going into much detail, here's the configuration I used to ret

Java: Use BigInteger in for-loop

In my previous post , I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it: Ordinary integers: for(int i = 1; i <= n; i++) {  //Task to do } BigInteger: for (BigInteger bi = BigInteger.valueOf(1);                 bi.compareTo(n) <= 0;                 bi = bi.add(BigInteger.ONE)) { //Task to do } here n is a BigInteger variable.
