tip : Shared Photo Stream on unsupported Mac

Question :

I would like to use Photo Stream and the Shared Photo Stream feature on my Mac running MacOSX 10.7, is that possible ?

Answer :

The answer is NO, officially not, but…

…if you’re willing to ‘risk everything’ for it, read on and there just might be an option for you…

Photo Stream is a great feature of iCloud, to upload your iPhone and iPad pictures straight to iCloud. Too bad, that on a Mac, it’s photos are only accessible from iPhoto 9.2.2 (or Aperture 3.2.3) or newer running on MacOSX 10.7.5 or newer…

And on top of that : Photo Stream is only supported for your primary iCloud account.

If you want to import/view photo’s from another iCloud account, you need to do that from a ‘Shared Photo Stream’. Only when running iPhoto 9.4 (or Aperture 3.4) or newer on OSX 10.8.2 or newer, you have the option to subscribe to a ‘Shared’ Photo Stream besides your primary iCloud account’s Photo Stream.

so… if you’re desperately seeking Photo Stream feature for your Mac, and you are even prepared to ‘risk everything’ (kind of) to get it, you might want to install a patched version of OSX 10.8 Mountain Lion on your ‘old’ Intel-Mac to get it.

Beware : installing a patched version of OSX 10.8 is unsupported, and not for beginners ! you should not install it on your ‘one and only’ Mac !

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.

For more info (and downloads), go to the info page on MacRumors.com :



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 :


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 :


or alternatively :


– 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 :


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


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

…that should be it !

fixed : OSX 10.8.4 update doesn’t install repeatedly

Question :

Each time I try to update my Mac’s OSX 10.8.3 to OSX 10.8.4 using the Mac App Store, I can see the updater is already downloaded, but when I get a message to restart my Mac to complete the install, and I click on it… my Mac restarts and finally turns out to still be at OSX 10.8.3…

Is there a solution for this ?

Answer :


It’s simple, but not obvious : do a manual install of the OSX 10.8.4 Combo Update which you can download here :


That’s it.
