Mountain Lion 10.8.4 Dmg

by

This tutorial shows you how to get Mac OS X 10.8.4 (Mountain Lion) running on a late-2006 Mac Mini (model A1176), which officially can only support up to Mac OS 10.6.8 (Snow Leopard), according to this Wikipedia article. Although I have not tested it myself, the same steps would probably work if you have an early-2006 Mac Mini.

Hardware upgrades

Mac Mini 2006 comes with a Core Solo or a Duo Core processor, whereas Mac OS X Mountain Lion requires at least a Core 2 Duo, so you will need to upgrade the processor on your Mac Mini first before continuing. Although it is possible to patch the installer to run on a Core Duo, I would still recommend upgrading for a straightforward installation experience. Compatible processors can be found on eBay for as low as US$20 and available at a wide variety of speeds – 2GHz, 2.16GHz or 2.33GHz. A detailed step-by-step guide on how to upgrade the processor can be found here.

Optionally, to make the whole process worthwhile, it is also recommended to upgrade the RAM. Although the Mac Mini 2006 comes with the Macmini1,1 firmware which can only support up to 2GB of RAM and will not boot if more than 2GB is installed, you can install up to 4GB (2 pieces of 667MHz laptop DDR2 SDRAM) by updating the firmware to Macmini2,1, originally meant for the Mac Mini 2007 family. The steps are summarized below:

  1. Download the newer firmware from here http://www.mediafire.com/?lfangrn69rxln3q and extract it
  2. Put the extracted files in /System/Library/CoreServices/Firmware Updates folder. Check the permissions of the files, or just do a chmod 777 on the files to be safe.
  3. Run the following command in terminal:
    sudo bless-mount /-firmware/System/Library/CoreServices/Firmware Updates/EFIUpdaterApp.efi-payload/System/Library/CoreServices/Firmware Updates/LOCKED_MM11_0055_08B.fd-options “-x-apple-efi payload0-data” -verbose
  4. Turn off the computer by shutting it down from the Apple menu.
  5. Wait for a few seconds and press the power button until the power LED flashes. Wait until the flashing stops.
  6. At this point the firmware upgrade is completed. You may see some distorted pictures on the screen, which is normal. Simply turn the Mac Mini off by pressing the Power button, and turn it back on
  7. After a reboot, the Mac Mini should recognize 4GB of RAM.
  8. If the machine doesn’t boot up or doesn’t recognize the extra RAM, check that the memory modules have been securely inserted. If it still doesn’t work, try to do a PRAM reset.

Preparing the installation

Before you proceed you will need to upgrade the OS on your Mac Mini to Snow Leopard 10.6.8, the last officially supported version. Next, get your Mountain Lion installer media ready – which can be a .DMG image or an actual DVD. After that, download MLPostfactor 0.3 from here, needed to patch the original Mountain Lion installer disk, which does not support the Mac Mini 2006, to run on your machine.

As at the time of writing this article (May 2015), MLPostfactor 0.3 only supports Mac OS up to 10.8.4. Versions 10.8.5 or above are not supported, so make sure that your installer is of the right version.

To make it easier to switch the boot partition without holding the Option key, you may also want to install a boot manager such as rEFIt.

Bypassing MLPostfactor limitation

Here comes the trick. The user interface for version 0.3 of MLPostfactor apparently only supports OS X Lion (10.7) and will refuse to run on 10.6. I tried to trick it by changing the system version number in /System/Library/CoreServices/SystemVersion.plist but things would still not work – MLPostfactor started but could not find Install OS X Mountain Lion.app in the Applications folder even though the installer was clearly there. A workaround would be to use MLPostfactor 0.2, which can run on Snow Leopard, to upgrade the system first to 10.7, and from there upgrade it to 10.8 by running MLPostfactor 0.3 again. I did not attempt this method because it seemed time consuming and most importantly, I had no installer disc for 10.7.

My relief came when I read this article which showed me how to use MLPostfactor from the command line. Apparently there is another MLPostfactor.app folder inside the original MLPostfactor app which can be invoked using the following command to patch the installer:

Surprisingly, there is no version check in the command line version of MLPostfactor and this method actually works to create the 10.8.4 installer partition. There are a few other commands that need to be done to patch the installer partition – refer to the original article for details.

Using MLPostfactor from bash script

A simpler way would be to use the MLPostfactor script written by pjherron available from github. With this script, the steps to upgrade to 10.8.4 from 10.6.8 on your Mac Mini can be summarized as below:

  1. Download MLPostFactor 0.3 and unzip it to desktop
  2. Copy the ‘Install OS X Mountain Lion.app’ folder from your 10.8.4 installer disc to the Applications folder
  3. Create a 8 GB or larger partition on the target drive to host the patched installer. The volume label should be Install and it should be automatically mounted at /Volumes/Install
  4. Create another partition, 20GB or more, on the target drive where you will install 10.8.4. Alternative, if you do not need the original Snow Leopard partition, you do not need to create this partition and can simply choose to install on the Snow Leopard partition later, losing all existing data.
  5. Run the upgradesl2ml.sh script and give it 30 minutes to an hour to complete. When done, reboot the machine and choose to boot from the 10.8.4 installer partition just created
  6. When prompted, choose to install 10.8.4 on the partition created in step 4, or simply overwrite your Snow Leopard partition. It is highly recommended to format the partition and perform a clean install – do not perform an upgrade as there are known issues.
  7. Let the installer run. The process will either end in an error or a white screen – this is normal. Reboot the machine when this happens.
  8. Choose to boot from the 10.8.4 installer partition again (not the partition where you installed 10.8.4 to).
  9. When the installer finishes starting up, choose MLPostfactor from the Utilities menu and let it repair the partition where you’ve just installed 10.8.4
  10. When the repair is done, reboot your system and choose to boot from your fresh Mountain Lion partition. It should boot normally
  11. Done, you can now enjoy Mountain Lion on your Mac Mini 2006!

If the installation is successful, the About This Mac dialog should show something similar to below:

Common issues

In my experiment, the final system runs fine without major issues. Application such as Firefox, Skype or even xCode and the iOS simulator could run well. VLC player works well to play normal DivX or Xvid videos. The only major application that is problematic is Dropbox, which couldn’t even install due to error ‘no mountable filesystems’ when mounting the installer DMG. Tuxera NTFS can install and appears to work but will later cause random kernel panic when browsing NTFS partitions in Finder. I had to resort to removing Tuxera and learn to live with read-only NTFS support for now.

If your dock in Finder appears to be transparent after the installation, open Terminal and run the following command to fix it:

Read here for other useful tips and tricks.

Other than the above issues, my installation of 10.8.4 on the Mac Mini is stable and serves me well as my daily work machine. My next attempt would be to install 10.9 (Mavericks) or 10.10 (Yosemite) on this computer. As far as I know, although there are proof-of-concept attempts, nobody has managed to get a stable working system yet, presumably due to challenges in getting graphics drivers to work properly.

Os X Mountain Lion Download

I own a Macbook Air and wanted to extract an OS X 10.8 Mountain Lion InstallESD.dmg from the Air. However as OS X 0.8 Mountain Lion came installed on my Macbook Air i could not obtain the InstallESD.dmg from the App Store.

In this topic, we share the download links of all MacOS X versions from 10.4 to 10.15: Catalina, Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard and Tiger - all original and downloaded from Apple Store. All the following shared MacOS Installer.app files had been originally downloaded from Apple Store. Both related.ISO and.DMG images. The current version of the Mac OS X Mountain Lion Golden Master 10.8 Final Build has been released and we have gathered all the direct download links for our readers. This final build is the most recommended and stable version of the Macc OS X Mountain Lion. Beside this you can also download the older version like OS X Mountain Lion 10.8.5.

So i needed some way to obtain the InstallESD.dmg, this would allow me to burn it to disc (if my Air had a DVD drive) create an installable USB stick for OSX or simply create an ISO so i can burn the install DVD on Windows.

It turns out you can extract a full OS X 10.8 Mountain Lion install disc from your Macbook Air / Pro quite easily. I found some old instructions on Macworld aimed at doing the same for OSX Lion on a Macbook Pro also worked for OSX Mountain Lion on my Macbook Air.

Here is how i obtained my InstallESD.dmg From my Macbook Air:

1. Open the Terminal, and type this command to list all partitions on your hard drive or SSD:

diskutil list

2. Look for ‘Recovery HD’ in the list, and note its identifier. It will be something of the form diskXsY, where X and Y are numeric digits, for me the identifier was disk0s3

3. Type the following command to mount the recovery HD:

diskutil mount readOnly /dev/[identifier]

4. Replace [identifier] above with the identifier you obtained from step 2. So on my machine, I typed:

diskutil mount readOnly /dev/disk0s3

Your identifier could be different

5. The disk image inside the recovery HD is invisible, so use the Terminal to mount that too:

hdiutil attach “/Volumes/Recovery HD/com.apple.recovery.boot/BaseSystem.dmg”

6. Now, from the newly mounted Mac OS X Base System image, double-click the ‘Install Mac OS X Mountain Lion’ application at the root of the disk.

7. Go through the license agreement. Once it asks you for a disk to install on, choose the external drive or spare partition. For this i used a 16gb USB memory stick.

8. Enter your admin password when prompted, and the installer will start downloading.

When the download has finished the installer will re boot your Mac, so we need to stop it from doing this.

MacWorld had the following tip:

Open an old-style (non-autosaving) application that still uses the traditional Save, Save As…, etc. commands in the File menu (I used TextWrangler) and make a new unsaved document, and type a few things in it. This will give you a little insurance against the installer rebooting the system, since the app won’t let the system reboot until you respond to its message asking whether you want to save the document or not.

I just kept an eye on it and force closed it before the timer counted to 0.

9. Once the file finishes downloading, the installer will extract the InstallESD.dmg image from it and delete the package. This will be fine as long as you don’t let the app restart your machine. Once the installer finishes download and prompts you to restart your Mac, force-quit it. Do this quickly, as it may automatically reboot for you after a 30 timeout period (although if you’ve got an unsaved document open, you should be able to prevent that).

10. Os x yosemite to el capitan. If we look at the USB drive we told OSX to save the data to you should see an OS X Install Data folder

11. Open the OS X Install Data folder and you will find an InstallESD.dmg

12. This is your full OS X 10.8 Mountain Lion install disc, you can burn it to a DVD, image it to a USB flash drive to create a USB installation disc or use dmg2iso to convert the DMG to an ISO which can be burned by a popular image burning application, such as ImgBurn on Windows. The ISO can be used on Esxi, VmWare and so on if you decide to convert the DMG to an ISO.

13. The end result is your choice of installation media for OS X 10.8 Mountain Lion, I wanted to obtain an ISO so i could install OS X 10.8 Mountain Lion on my VmWare Esxi Server. As you can see OSX 10.8.3 was downloaded, as 10.8.4 was only released a few days ago i imagine eventually you should be able to get an up to date install dmg by doing this.
