Posts about MacPostFactor written by MacManus.nl. Question: I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install. Macos extractor, macpostfactor apps guide through patching, installing os x el capitan (10.11), yosemite (10.10), mavericks (10.9), or mountain lion (10.8) on older mac. Thread focuses on os x el capitan. Macpostfactor works mountain lion, mavericks, yosemite, el capitan.
Question :
I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install.
Can you give me any directions ?
Answer :
Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements can be done using MacPostFactor (MCPF).
MacPostFactor (MCPF) also supports installing OSX versions up to OSX 10.10 Yosemite on older Macs. And a new version that supports installing OSX 10.11 El_Capitan is in the works.
For more info (and downloads), go to the info page on MacRumors.com :
or see the (less readable) official page of the MacPostFactor team :
…in short :
!!! THIS IS FOR (RATHER) EXPERIENCED MAC-USERS ONLY, AND SHOULD NOT BE DONE ON YOUR ‘ONE AND ONLY’ MAC !!!
!! REMEMBER : DO FOLLOW THE COMPLETE INSTRUCTIONS THAT CAN BE FOUND HERE : MacPost Factor info page on MacRumors.com
…that should be it !
enjoy !

March 3, 2014 8:29 am1 CommentIn this post I will tell you how to install Mountain Lion on an old Mac running Snow Leopard.
You will need:
1. A Mac that is supported by MLPostFactor (and is running pre-Lion OS X)
2. A distribution of Mountain Lion from the App Store
3. Time and patience
4. optional A cassette or CD player, or an iPod.
5. Some basic Terminal knowledge
For a start, rock up some music on your player, since the process is gonna take some time for sure.
Step 1. Partition the disk
You will need to make your disk into three partitions. The first one would be your current one containing Snow Leopard. The second one will contain the fresh installation of OS X Mountain Lion. The third one is the installer disk.
Make sure to create the installer partition at the end of the disk: that way you will be able to delete it and expand the OS X partition later.
Step 2. Create the installer disk
Fire up Terminal. Enter the following command:
cd /path/to/MLPostFactor.app/Contents/Resources/MLPostFactor.app/Contents/Resources/
This is not a mistake, there is really another app inside MLPostFactor!
Next, make sure the “Install OS X Mountain Lion.app” is in the /Applications folder and is about 5 gigabytes in size.
NOTE: Pirated copies, Installation disks and Disk images are NOT supported!
Then type this in terminal:
sudo installer -package Base.pkg -target /Volumes/Your installer disk name
This will create the installer disk. On my Late-2006 MacBook Pro it took almost an hour so this is the time to go for a lunch.
Step 3. Patch the installer.
Once it’s done, enter the following command in terminal.
replace Graphics_2 with Graphics for pre-10.8.1 (AFAIK — didn’t attempt to install pre-10.8.1)
for PACKAGE in Components.pkg Graphics_2.pkg Kernel.pkg; do; sudo installer -package $PACKAGE -target /Volumes/Installer Disk Name; done
This will install the remaining patches.
Step 4. Install OS X
Reboot your Mac to the Installer partition. Install OS X Mountain Lion to the MountainLion partition. The installer will FAIL and it is normal! After the installation failed message, select the MLPostFactor tool from the Utilities menu. Point it to the freshly installed Mountain Lion setup. Let it work on it’s patches and when it’s done, reboot to your fresh Mountain Lion setup!

(optional) Step 5. Fix System Version
If you were installing 10.8.5 and selected 10.8.4 in PostFactor, the OS thinks it’s a previous version.
Go to /System/Library/CoreServices. Copy SystemVersion.plist to desktop. Edit the desktop version to read your system version instead of 10.8.4 everywhere inside it. Then drag the new one back into CoreServices, overwriting the old one. You’re done.
Congratulations on your new old Mac!
