[Guide] Success! Install 10.8 on old unsupported Mac

[cmaus]

Regarding Recovery HD

Hi! I am wondering if can we install a recovery partition in mlpostfactor? I wanted to use the "Find my Mac" feature but it can't because it needs a recovery partiton here. TIA

I use this to successfully create a recovery partition of any desired version, appending it to any desired partition:

http://www.ivanexpert.com/blog/2012/09/create-or-update-a-lion-or-mountain-lion-recovery-partition/

However, if your Mac doesn't boot stock ML, creating a ML recovery partition with this will succeed, but you cannot boot from it.
Maybe HackerWayne can read my post too and use this tool to make a Recovery HD - installer that contains a modified Recovery HD image that also contains the MLPostfactor Tool (which would anyways be handy to have).

You may however, still create yourself a Lion Recovery HD if you got a white MacBook for instance. Because those will still officially boot Lion.
And your MLPostfactor'd Mountain Lion system won't care. It will enable you to use FileVault and Find my Mac.
Tested it myself! #

MLPF can't find .app file

Hi
When I run MLPF v0.3 i get the error message, that "Install OS X Mountain Lion.app" can't be found in my Applications folder. I have already tried to change my system language to english as has been proposed earlier in this thread.

Im currently running 10.7 and it's a iMac ultimo 2006 with x1600. Any help would be very much appreciated.

Look and see. Is there a copy of "Install OS X Mountain Lion.app" in your Applications folder? MLPF should recognize localized names for the Applications folder.

Thanks for the answer. Yes, the file is in the applications folder, and I'm 100% sure that the file name is correct.. What could be the problem then? Should I update my current OS ?

Is that somewhere around step 8? With 10.8.5 installer my 2007 mini (Intel GMA 950) went to a blackish screen rather than telling me "Installation Succeeded". After waiting an hour to be sure it wasn't just thinking real hard, I turned the power off and option-key booted into the efi install partition again. Once that came up, I could carry on through step 9. With that done, the mini'll boot under Mountain Lion. "About This Mac" says 10.8.4 despite my 10.8.5 installer. Probably just one of the patches causing a cosmetic issue. The system's been remarkably stable since the update, so it's worth going through a few fraught moments during the update process.
Applied the security update 2014-01 afterwards
First modified SystemVersion.plist as described by krackpot.
Changed every instance of 10.8.4 in plist to 10.8.5 plus the "MLPostFactor v0.3" string.
Then rebooted and downloaded Security Update 2014-001 (Mountain Lion) from Apple and installed.
Everything came up nicely after the install and reboot.

What did you type to replace "MLPostFactor v0.3" string? The build number of 10.8.5? If so which one. 12F37 or 12F45?

 

[krintel]

I updated my OS to 10.7.5, and now it is working.

 

[Partron22]

IIRC it was product build version that had "MLPostFactor v0.3" in it. I just put 10.8.5 in its place. That seemed to satisfy as far as doing Security update 01-2014
Here's what the Mac's Systemversion.plist file looks like now, in a text editor:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>ProductBuildVersion</key>
<string>10.8.5</string>
<key>ProductCopyright</key>
<string>1983-2013 Apple Inc.</string>
<key>ProductName</key>
<string>Mac OS X</string>
<key>ProductUserVisibleVersion</key>
<string>10.8.5</string>
<key>ProductVersion</key>
<string>10.8.5</string>
</dict>
</plist>

Perhaps if I used a build number for the BuildVersion string Auto security update through store would work? I'm not going to mess with that further as Apple always has security updates available through their downloads page, and I prefer manual anyway.

Good on you, krintel

- you have to be on 10.7.5, the last Lion version
- is it a genuine copy of ML? Or a downloaded copy? These can be stripped down, be sure to get a genuine, full, installer-app

Bluetooth problem

Having used MLPostFactor for 2 weeks, I discovered that the Bluetooth preference pane closes when I try to open it. Someone knows the solution?

 

[Partron22]

Having used MLPostFactor for 2 weeks, I discovered that the Bluetooth preference pane closes when I try to open it.

Same here, not good.
So I grabbed a copy of System/Library/PreferencePanes/Bluetooth.prefPane from a Lion System (10.7.5) and replaced the Bluetooth.prefPane on the Mountain Lion Mac (10.8.5). I kept a copy in case of disaster.

Now the Bluetooth pref pane comes up under Mountain lion, and appears to function normally.

Regardless, it'll be a few months before I toss that copy I made of the official 10.8.5 prefpane.

All other preference panes look to open normally, except mouse, which just asks that Preferences be allowed to restart before it'll open up. I didn't check preference panes in the "other" grouping, such as GeekTool or Growl because third party panes'll vary from user to user.

Please could you send it compressed into a zip? I have not installed OS X Lion. I really appreciate it.

Bluetooth and WiFi problems

Hi I'm a new member and this is my first posting. I successfully installed ML on my late 2006 iMac 2GHz C2D 3GB memory and Graphics ATI Radeon X1600 128 MB, using MLPF. It is on a Panasonic SSD 840 EVO as internal disk.

My version of ML says it is 10.8.5

My question is can anyone tell me why I am having problems with:-

1 bluetooth and

2 WiFi?

I cannot get bluetooth to connect with anything, neither mouse or trackpad, yet they work fine in Lion.

I can connect WiFi to my Airport if I use the Guest Network - which has no encryption but NOT to my normal WPA2 Personal network.

Also, I did not have a recovery partition on my iMacs internal Lion HDD. Is that why there is none on my ML SSD?

I know it might mean some more work however since your dealing with an ATI X1600 machine, personally I would ditch your OS X 10.8.5 MLPF install in favor of this and you will not be dealing with any Bluetooth nor Wi-Fi issues:

First and foremost in constructing/compiling your system, remember that google is your friend.

Use the app “Kext Wizzard” or the appropriate terminal commands for installing additional/needed kext files. It is also necessary to have another bootable OS system (Snow Leopard/Lion) so that you can mount your Mountain Lion system on it and have access to it while building it. I would recommend OS X 10.7.5 Lion as all the kexts files needed (except VoodooHDA.kext) are contained in that OS X system and therefore one would be "killing two birds with one stone" in that respect.

Starting with using the full OS X 10.8.4 (app store).app follow this excellent guide by dead.xx in creating your installer: https://forums.macrumors.com/threads/1404548/.

***The ONLY difference one needs to make in the dead.xx guide is that instead of using the supplied "boot.efi" file found there instead, use Tiamo's "boot.efi" found here: https://forums.macrumors.com/showthre...1598176&page=2***

Once created, install OS X 10.8.4. Once completed, restart though restart to your supported OS system and not your Mountain Lion drive/partition at this point.

Using the .app “Kext Wizzard” and with your Mountain Lion drive/partition mounted on the desktop, select the appropriate mounted mountain lion drive/partition in the pull down tab, and install the following kexts found in both of these download links:

Also and again while having the Mountain Lion drive/partition mounted, open the following folders in this sequence: System/Library/Frameworks and locate both the OpenGL & OpenCL folders and move them both to the trash and delete them. Once deleted, copy both patched versions of the same namesake (Google !!!) into the same System/Library/Frameworks folder.

That basically should get anyone with an unsupported Mac possessing ATI X1600 graphics a “non MLPF” OS X 10.8.4 64 bit OS system that I have estimated @ 100 % full functionality.

Very grateful for such a lucid and complete post!

gpatpandp I didn't expect to receive such a helpful response so soon, thank you!

I have been running on 10.7.5 on the original 500GB HDD. I believe it originally had Tiger (10.4.7) installed. Leopard and Snow Leopard were subsequently installed by the previous owner. I upgraded to Lion, everything went smoothly and worked well, with occasional beach balling, but nothing I couldn't live with on an old machine!

I have it and one other identical system on a fiber broadband network, backing up to an AirPort Time Capsule with 2TB of capacity wirelessly. So far so good. My daughter uses the other iMac for her academic work so it is vital to have functioning backups. Then I discovered accidentally that on neither system is there a Restore Partition. I found a walkthrough on how to construct such a partition (which needs a copy of the full install Lion media) and realised that I should have kept my Lion thumb drive, which I had sacrificed to make one for ML which I recently installed on an MBP. Having this find 'put up the hare' to install ML on an unsupported Mac and hope it will also create a restore partition. Having read further, I now see this does not fit the bill, not at least with MLPF!

Help with clarifications? 64-bit Kernel on MacBook 2,1

Deep thankyous to dead.xx, hackerwayne, archy and everyone else who has worked on this! I _think_ I understand what to do, but I'd really appreciate someone expert checking a couple of questions before I go and screw up my system.

I'm working with a Macbook 2,1. I need to run a 64-bit windows system as a VirtualBox guest on my MacBook 2,1. Trying to install it under a 32-bit OS fails, because VB requires 64-bit kexts to support the 64-bit windows. I think I would hit the same issues under MLPostFactor, - that it would still be using 32-bit kexts, so that VB would run in 32-bit mode. Is my understanding on that correct?

If I'm wrong, and I can use MLPF, how do I determine what version of OSX to specify? Before I realised the 32-bit MLPF version probably wouldn't work for me, I already tried to install via MLPF. I got the ML installer from play store, but the app doesn't say which version it installs. I tried guessing that they were still using their old procedure, shipping the installer for 10.x.0, then expecting you to upgrade after installation. So I specified 10.8.0. That didn't work (the OSX installer hung in a black screen at the end of installation). So then I guessed 10.8.5. Same result. Any thoughts?

If I can't use MLPF, dead.xx's method looks like the simplest available, but there are some issues that I don't fully understand (posting here because that thread seems to have become moribund).

I think because the GMA930 graphics card isn't supported directly in dead.xx's system, just following his instructions would result in an ML that would boot to a black screen, is that correct? So I have to install the GMA930 64-bit kext into the installer, I can't install the kext after creating the system, right?

The only way I can see to do that is to boot the installer disk on ML-compatible hardware, before dead.xx's step 9 (see below for an excerpt), in an ML-capable machine as per Archy's (post 90) instructions, and use KextUtility.App to install the 64-bit GMA930 driver (and maybe a sound driver as well). Is there any other way to do this? After doing that, I go back to dead.xx's steps from step 9 on, is that right?

I'm completely unsure whether dead.xx's method will affect the Lion and Snow Leopard installations I have on other partitions. Does this method touch any partitions other than the ML one? Will the other OSs still boot if there are any problems with ML?

Thanks again for any (additional) help.

6, restore Mac OS X BaseSystem to your installation source
7, copy mach_kernel from the root dir of Mac OS X Install ESD to the root dir of your installation source.
8, copy Packages from the root dir of Mac OS X Install ESD to /System/Installation of your installation source and replace the original one
9, copy OSInstall.mpkg of from the patch to /System/Installation/Packages of your installation source and replace the original one

I just realized that my walk through post has become a tad confusing as it contains information concerning the VoodooHDA 2.8.4.kext which is no longer needed so I have refined it to be accurate with only the necessary steps, links, and information needed:

ALSO regarding a recovery partition firstly, you will have to create one manually as your Installer formulated from the dead.xx guide will not do so.

You have two choices when creating a recovery partition, you can elect to create one using an app such as the one found here:

https://github.com/MagerValp/Create-Recovery-Partition-Installer

…and create a Mountain Lion Recovery Partition which will require you to replace the stock boot.efi with Tiamos boot.efi files just as was necessary in building your installer OR use the same app and create a OS X 10.7 Lion recovery partition which of course will boot on its own accord without any manipulation involved.

Thanks gpatpandp, I really appreciate your help - if I can save hours of trying your combined dead.xx/gpatpandp method only to have it fail, that's a huge win. Can you walk me through the reasoning? Is it that ML graphics require calls that won't be in the 64-bit GMA950 kext from Snow Leopard? If so (since I don't really need ML, I think any 64-bit OSX will do for VB so long as it is using 64 bit kernel and extensions), would a better option be to try to switch from 32-bit to 64-bit Lion? And if that's the case, could I essentially follow your guide, using the Tiamo boot.efi and the 64-bit GMA950 kext, but building from the Lion rather than ML installer? Do you foresee any nasty tricks and traps in that?

Well, in the end I decided to bite the bulllet - and guess what: it worked! So the steps I took were in essence what is described in your guide just above, with a couple of exceptions: after step 8 of dead.xx's guide (i.e. at the same time as installing Tiamo's boot.efi), I also used kext wizard to install the 64-bit drivers from 10.6.2 (these can be fairly readily found - google GMA950 64 bit 10.6.2, or see message 401 in this thread). Then at your final kext-installation step, I omitted the ATI drivers, just adding AppleHDA and IOAudioFamily from forums.macrumors.com/attachment.php?attachmentid=462845&d=1393544777.
There are a lot of comments on the limitations of these drivers, so I'm not expecting great video performance - but then I don't need it. What's more important to me is that the Win 64-bit installation under virtualbox is working!

So thank you again, both to you and to all the others who have created these tools - hackerwayne, dead.xx, Tiamo and countless others.

 

[nickbw]

How did you get kext wizard to do that? I have been trying this all afternoon. Just when I think I am succeeding I get a failure. It appears that the disk is ejected (I see the disk light go out on the drive) and Kext wizard hangs for a long while, with the blue and white striped progress bar stalling, and then the app quits. I get an option to send a log to Apple or to reopen the app. Yes I'm doing it via an external HDD on my MBP with a copy of Snow Leopard and a thumb drive of Mountain install made from a download from Apple app store.

Sorry, been a bit busy on other things. The only obvious difference between your and my experience is that I ran kext wizard from Lion rather than Snow Leopard. Not sure if/why that would make any difference, but it worked for me. If you can't get it to work, there are other gui kext tools around (though kext wizard is the prettiest, and I'm guessing may be the easiest). Oh one other thought - any risk that your thumb drive is running out of space?

... after step 8 of dead.xx's guide (i.e. at the same time as installing Tiamo's boot.efi), I also used kext wizard to install the 64-bit drivers from 10.6.2 (these can be fairly readily found - google GMA950 64 bit 10.6.2, or see message 401 in this thread).

There are a lot of comments on the limitations of these drivers, so I'm not expecting great video performance - but then I don't need it. What's more important to me is that the Win 64-bit installation under virtualbox is working!

Just wanted to add a bit more detail:

1. Sound isn't working, but it is not relevant to my application, so no worries
2. The monitor doesn't sleep; at the moment I'm just using a black screensaver, but that doesn't save energy or the backlight, so if anyone finds any hacks to overcome this, I'd really appreciate knowing
3. I thought the drivers were causing a problem with using vnc to connect to apple's screen sharing - spent many hours on this. Turns out it's a bug in ML screen sharing, not related to the kexts at all. RealVNC's vnc server works perfectly.
