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 :


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 : 10.7.5 refusing to see the Atheros AR9280

I must admit the title might be a little misleading, since I have not had anyone claiming problems like the “WiFi: no hardware installed”-error with the Atheros AR9280 AirPort-card and MacOSX 10.7.5 yet, but still…

…that is probably due to the fact that the MacOSX 10.7.5 updater doesn’t overwrite the IO80211Family.kext system extension. So if you are upgrading from an earlier version of MacOSX 10.7 “Lion” which you had already ‘patched’ for use with the Atheros AR9280, you won’t get any (new) issues…


If you do get the “WiFi: no hardware installed”-error after upgrading to MacOSX 10.7.5 (e.g. from MacOSX 10.6 “Snow Leopard” or earlier), you can just do the same ‘patch’ of reinstalling the old IO80211Family.kext system extension. Instructions for doing so can be found here :

info : are you ready for Mountain Lion ?

Apple is getting everything in place for the release of OSX 10.8 “Mountain Lion” due later this month.

The names of the Macs that will be able to run OSX 10.8 “Mountain Lion” have been published on the Apple website :

From eldest to newest these Macs are :

– iMac “mid 2007” or newer (so any “Aluminum” iMac)

– MacBook Pro “mid/late 2007” or newer (so any MacBook Pro with an NVIDIA graphics card)

– Mac Pro “early 2008” or newer (so any Mac Pro with the Xeon 5400 “Harpertown” processors or newer)

– MacBook Air “late 2008” or newer (so any MacBook Air with Thunderbolt or MiniDisplayPort)

– MacBook “Aluminum” = “late 2008″ (so the 13” MacBook Pro look-alike)

– MacBook “White – early 2009” or newer (so only the ‘original’ white polycarbonate design versions that have an NVIDIA graphics card)

– Xserve “early 2009” (so only the latest generation with Xeon 5500 “Gainestown” processors)

– Mac mini “early 2009 & late 2009” (so only the original Mac mini design that have an NVIDIA graphics card)

– Mac mini “Aluminum” = “mid 2010” or newer (so any Mac mini of the extra flat redesign)

…that’s the bad news (for some  – those of us with older Macs…)

and the good news is :

you don’t need to have MacOSX 10.7 “Lion” installed to upgrade, you only need MacOSX 10.6 “Snow Leopard” with the “Mac App Store” application (since OSX 10.8 “Mountain Lion” is only available from the Mac App Store…)

info : setting up Back To My Mac through a TG712 modem-router

Question :

How do I setup my Thomson TG712 modem-router to allow me to use the the Back To My Mac function of my Macs ?

Answer :

Here’s how to turn on Back To My Mac when you have a TG712 modem-router :

– on your Mac, go to Apple —> System Preferences —> iCloud

– then put a check mark at “Back To My Mac” to turn the service on

– if there’s a “More…”-botton click it, just for your information ; if a warning is listed, read it, keep it in mind, and don’t bother…

– then open Safari (or any other internet browser) on your Mac, and type the web based control panel’s IP-address of your router-modem as the URL ; for the TG712 router- modem, the IP-address is

– in the web based control panel, go to “Toolbox” (in the menu on the left) –> “Games & Apps Sharing” (in the menu on the left)

– then in the middle of the page, at the bottom, from the “Choose a task…” list, click on “Add a game or application to a local networking device” (the first link in the list)

– in the page that opens, put check marks both at “Use UPnP:” and “Use extended security:”

– and set the “Game or App”-dial (the one that is initially at “ABC (Another Bittorent Client)”) to “Back To My Mac”

– set the “Device”-dial to your Mac (which is the Mac that you would like to use with Back To My Mac, so probably your Mac-server or desktop-Mac)

– just to be able to trace possible errors, put a check mark at “Logging”

– then click on the “Add”-button

– wait for the router-modem to restart

– logout by closing the browser-page with the web based control panel on it

Now you should be able to log into your (home) Mac, when being at a remote location (if there’s internet connection there…)

fixed : installing a new hard disk (option 1)

Here’s a simple 3-step way of replacing a HD in a Mac :

[ in this example a new HD is put into a Mac mini (version mid 2007) ]

1- clone the internal HD directly onto the new HD
These instructions assume you have another Intel-Mac and a USB-enclosure for a SATA-harddisk (that you will afterwards use to turn the old internal HD into an external one) available :
– put the new harddrive into the USB-enclosure
– connect the USB-cable to your other Intel-Mac
– connect the Mac mini to the Intel-Mac using a FireWire-cable
– (temporarily, just during startup) connect a USB-keyboard to your Mac mini
– startup the Mac mini while pressing the T-key on the keyboard (“Target Mode”)
– both the Mac mini and the USB-connected new HD will now show up in your Finder (on the Intel-Mac)
– open Disk Utility
– click on the Erase-tab
– select the USB-connected HD list on the left, and erase it in MacOS Extended (Journaled) format
[ BEWARE : do NOT format your HD in MacOS Extended (“Case-sensitive” Journaled) mode ! As that will prevent some applications to run ! e.g. Adobe Photoshop 10 Editor ]
– click on the Restore-tab
– from the list on the left drag the partition of your Mac mini onto the “Source”-field
– then drag the new partition from your new HD onto the “Destination”-field
– click the Restore-button, and wait

2- replace the HD
– open the instructions on how to replace the HD from the iFixit-website (or print them out) and read them

– get the new HD out of the USB-enclosure
– now gently open the Mac mini enclosure
– blow the dust of the interior using a compressed air blower [ do NOT use a hair dryer ! ] or using a vacuum cleaner with a piece of thin cloth (e.g. a napkin) tightly fit to the suction tube (to prevent anything from actually being sucked in)
– replace the HD (make sure the connectors are clean and fit thight)
– while you’re at it, you might also check the AirPort-card connector
– and finish up (all using the iFixit-instructions)

3- test the new HD
– restart

fixed : quickly share your Mac’s internet connection to your iPad

Question :

I just got myself a WiFi-only iPad, but I have no WiFi reception in my living room (that’s why my Mac in my living room is connected to my network through an Ethernet/UTP-cable). Is there an easy way to get internet connection on my iPad in my living room ?

Answer :

Yes, there is.

Your Mac can share it’s internet connection from one of it’s internal network-connections to another. So from Ethernet to WiFi in your case.

To get it working is easy :

– turn on your Mac (if your Mac isn’t running, this won’t work)

– go to System Preferences (under the Apple-dropdown menu in the upper left corner of the desktop/Finder-menu)

– in the window that opens, click on “Sharing”

– in the screen that opens, click on “Internet Sharing” in the list on the left

– then, on the right, select your incoming network/internet connection at “Share your connection from:” (so, in this case select “Ethernet” there)

– and then select your outgoing internet connection at “To computers using:” (so, in this case put a check mark at “Wi-Fi”)

– if you want your shared internet to be password protected, click on the “Wi-Fi Options…”-button and choose your preferred network name, the preferred password protection protocol and your preferred password. If you don’t need protection, just leave everything as-is.

– then put a check-mark at “Internet Sharing” in the list on the left and quit System Preferences

– now you will see that your AirPort/WiFi-pie icon in the upper right of the desktop / finder-menu has turned into a new icon with an arrow pointing upward.

– then, on your iPad (or iPhone or any other WiF-connectable device) go to Settings, click on WiFi and select your new local WiFi-network

– done ! enjoy !

Note : you’ve just turned your Mac into a local WiFi-router (also), so remember that your Mac has to be switched on to sustain the WiFi-network connection

tip : planning on buying Apple stuff ?

If you’re planning on buying Apple hardware, be it an iPod Shuffle, iPod Nano, iPod Classic, iPod Touch, iPhone, iPad, MacBook Air, MacBook, MacBook Pro, Mac mini, iMac, Mac Pro or Cinema Display, you should consider checking if now is the right time to buy first.

MacRumors’ Buying Advice doesn’t advice you on what product to buy, just on WHEN to buy and when not to buy (which means : “hold on and wait just a little until the product gets refreshed”) :

MacRumors’ Buying Advice is based on the regularity of the product cycles of Apple hardware (not on the rumors, but current rumors on upcoming hardware are listed also …as MacRumors originally is an Apple rumor site…)

The ‘advice’ categories are :

Buy now! Product just updated

Buy only if you need it – Approaching the end of a cycle

Don’t buy – updates soon
