fixed : install OSX 10.11 El_Capitan on unsupported Macs

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 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.

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 !

fixed : install OSX 10.8 Mountain Lion on unsupported Macs

Question :

I read somewhere that it is possible to install the latest version of OSX 10.8 Mountain Lion on my Mac, even though the official installer refuses to install.

Can you give me any directions ?

Answer :

Updated answer :

MLPostFactor has been succeeded/replaced by MacPostFactor, and is now being updated by a new crew of programmers. MacPostFactor 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.

Original answer :

Yes, thanks to the guys from MLPostFactor, it’s now possible to install OSX 10.8 Mountain Lion (even 10.8.4) on these older Intel-Macs :

Early 2006 (and newer) versions of the iMac and Mac mini

Late 2006 (and newer) versions of the Macbook, MacBook Pro, Mac Pro and Xserve

Early 2008 (and newer) versions or the Macbook Air

…and I must say : “(in my case) it runs smoother than MacOSX 10.7”, but there are a few downsides, especially these ones :

– regular OSX updates are disabled, you can only use a special OSX-update routine

– some (but very little) software is not compatible due to various reasons ; e.g. PhotoBooth, Little Snitch

– the SMB client is not working properly (the SMB server is), so file transfer is crippled

– it’s provided “as-is”, so no support from anyone (neither the developer nor me), and no guarantee it will fully or even partially work in your case (especially not if you do not strictly follow all of the directions !!)

…in short :

!!! THIS IS FOR (RATHER) EXPERIENCED MAC-USERS ONLY, AND SHOULD NOT BE DONE ON YOUR ‘ONE AND ONLY’ MAC !!!

What you need :

– one of the Intel-Macs mentioned above (running MacOSX 10.7 Lion and at least 2GB of RAM)

– an official version of the OSX 10.8 installer, (re)downloaded from the Mac App Store inside your Applications Folder (sorry, pirated versions don’t work…)

– the 32-bit MLPostFactor v3.0 installer-patcher (should be put inside your Applications folder also) you can download from here :

http://www.osxhackers.com/Download.html

or alternatively :

http://mac.softpedia.com/get/System-Utilities/MLPostFactor.shtml

– a full backup of your current harddrive running OSX 10.7 Lion and all your personal files (simply put : “a Time Machine backup of your Mac”)

– a partition of 8GB to create the patched OSX 10.8 installer on ; according to the official directions this should be a partition on your main harddisk called “Install”, but it turns out that ‘if you dare’ you can also use an 8GB USB-stick or an 8GB partition on an external USB- or FireWire-harddisk for this [simply put, MLPostFactor does what Lion DiskMaker does AND includes a patch that’s needed for older Intel-Macs]

– a partition of at least 10GB called “ML” to install the new (patched) OSX 10.8 Mountain Lion onto ; this is will to be your final, ‘new’ harddrive for your ‘old’ Mac… it turns out that ‘if you dare’ you can assign this to your current MacOSX 10.7 Lion harddrive [provided you have a good (TimeMachine) backup]

Exact directions on how to install can be found here :

http://www.osxhackers.com/Installation.html

…or the video that HackerWayne (one of the MLPostFactor developers) has issued :

http://www.youtube.com/watch?v=YqMgrPKfrqM

You should follow the step-by-step instructions above, but just to give a quick impression of the routine :

– make a Time Machine backup and make sure both the OSX 10.8 installer and MLPostFactor are in you Applications folder

– run MLPostFactor to create the patched installer (8GB) for OSX 10.8.4 (or an other version if you prefer that one for some reason…)

– reboot from the patched installer and install the patched OSX 10.8 onto (the desired partition of) the internal harddrive

– this will either end in an error or a white screen (seemingly ‘hung’)

– reboot from the patched installer and run MLPostFactor from there onto the partition you have just installed OSX 10.8 on (= your internal harddrive)

– then reboot from the fresh OSX 10.8 partition (= your internal harddrive)

– if you get a “WiFi: No Hardware Installed”-error, get the KextUtility for OSX 10.8 and install the Edited Atheros Kext for Lion*3

tip : put a OSX 10.8 “Mountain Lion” installer on a USB-stick

If you just have one Mac you want to install OSX 10.8 “Mountain Lion” on, you can just (buy and) download the installer from the Mac App Store.

But if you need to install OSX 10.8 “Mountain Lion” on multiple Macs, the fact that the download process regularly is very slow, will make you want to skip the downloading if possible.

You can do so easily by creating a dedicated USB-stick with the OSX 10.8 “Mountain Lion” installer on it, which is quite easy :

– get yourself a brand-new 8GB USB-stick

– buy & download OSX 10.8 “Mountain Lion” from the Mac App Store, but… you need to make sure the installer will not be ‘cleaned up’ (= deleted) after the installation has finished : the easiest way to do so is to wait for the download to complete, and then when the installer window pops up, do not start to install right away ; first, go to the Finder and into the Applications folder, then right-click on the “Install OSX 10.8 Mountain Lion” application, and select “Compress “Install OSX 10.8 Mountain Lion””… then wait for the compression to complete… when that’s done, you can continue to the installer window and install OSX 10.8 “Mountain Lion”

[ if you’ve already installed OSX 10.8 “Mountain Lion” and the installer has already been ‘cleaned up’ (= deleted), you need to re-download OSX 10.8 “Mountain Lion” from the Mac App Store ]

– download the “Lion DiskMaker” app from here :

http://blog.gete.net/lion-diskmaker-us/

– then double-click on the .zip-version that is now/still in your Applications folder ; that will place the original installer application back

– then run the “Lion DiskMaker” app, and follow the instructions given

…it’s that easy

Note :

– additional instructions can be found on the page that you’ve downloaded “Lion DiskMaker” from

– reformatting of the 8GB USB-stick will be done by the “Lion DiskMaker” app also

– it is highly recommended to create the installer on a dedicated USB-stick ; even though it is possible to burn the installer to a DVD, do not do so, since that will be extremely slow to startup from during installation – also, do not put the installer on a (partition of) a external drive that has other data on it… it might wreck your data if things mess up during creation, and it’s not as practical for actual use…
