Snow Leopard on Acer Aspire One: Part 17: Updating to 10.6.7

Sunday, September 4, 2011

Now and days, 10.6.4 is not good enough to be secure and get the most out of Mac OS X. However, if you tried to update from where we left off, you may have noticed an obstacle course. There is a simpler way but you’ll need to do a few things first – and it may not always be successful.

Update: This article is meant for the Acer Aspire One. If you want an updated and more general method, click here.


Two Partitions
The first partition must be installed as per Part 3 and updated to 10.6.4.
The Second Partition must be in Mac OS X Extended Journaled format.


Mac OS X 10.6.4 Update
Mac OS X 10.6.5 Update
Mac OS X 10.6.6 Update
Mac OS X 10.6.7 Update


A combo update to 10.6.6 and 10.6.7 will not work, it is best to go the long way. I have only got this method to work once, but if it works for you, then all the better. I do not guarantee success like I can with the other tutorials, feedback on the process would be much appreciated.
Once you have the above prerequisites ready, you will install iAtkos s3 v2 as per Part 3 on your second partition but with some minor tweaks.

In Part 3, I tell you that one of the drivers that you need to install is SleepEnabler.kext. In this run, we will NOT choose Sleep Enabler. You also don’t want to install any boot loader at all until this text tells you to.
Once your Mac has been installed as per Part 3, you will then get the internet working as per Part 5.

Then, you will want to run the 10.6.4 set up and install. Before, we had to do some things before restarting. This time, since Sleep Enabler isn’t in the picture, we don’t have to. The boot loader also has its own kexts which act to interfere and become less stable as you climb the update ladder. By not having an installed boot loader at this time, the updates will be painless. So in other words, install 10.6.4 like a normal install and Restart when its done.

For those who need to do the update from the secondary partition (essentially, the direct update fails or crashes at boot), here is how it works.

You install a Partition A with 30GB (bare minimum) and install a Partition B with the desired amount of space to 10.6.3 using the previous tutorials.
Then, you boot into Partition A, run the update and Change the Install Location and choose Partition B. Then you Restart.
At the Boot loader, Boot into Partition B and then fix whatever kexts that you have to using another article in the series.
Then Reboot Back into A to install the next updates to Partition B and repeat this process until you reach 10.6.8.

You will notice that you won’t have any issues when you boot up – apart from the graphics. We will ignore this for now as we will fix it once we get to 10.6.7.

Now, install 10.6.5 as you would a normal install and then before restarting, install the internet kexts as per Part 5.

Again, no issues or kernel panics and we load into 10.6.5 where we will now install 10.6.6. This update will break the internet again so we will reinstall the internet again before we press restart as per Part 5.

Now we are in 10.6.6 and the process of getting here is as fast as it is in this article. From this point, you have the Mac App Store and performance improves. We are not finished yet, however.

Run the 10.6.7 installation and restart.

Once you have restarted, you will be in Mac OS X 10.6.7. Now that we are here, we can restore our broken graphics, boot loader, and battery if you are on a laptop.

Before we do this, I want to tell you what happened with me. Once I got to 10.6.7, with 10.6.4 on the previous partition, I decided to test to see if the kexts that worked were from the 10.6.4 partition and indeed these kexts broke when I wiped out the 10.6.4 partition.

I also had to repair the boot with –y.

At this point, I wanted to repeat my process in the now empty 10.6.4 partition and it didn’t want to work properly. So, I went into disk Utility and copied the 10.6.7 partition over to the old 10.6.4 partition and both of my partitions ran 10.6.7. From this point, I managed to fix everything while going back and forth between partitions whenever one of them wouldn’t boot properly to go to Disk Utility and Repair the Disk Permissions.

However, if you don’t touch the 10.6.4 partition, you will not have to go through the more painful part of this process and are pretty much done.

Now, if you decide to delete the 10.6.4 partition, the following kexts and install instructions will be needed.
First up, comes the Graphics.

Restoring Graphics in 10.6.7

If ever you need a kext, is your place to go. For all of the Aspire One people out there, I have uploaded the kexts that I used to make things simpler. For the others, you will need to find the kexts that are appropriate for your respective systems.

This will get the translucent menu bar, ripple effect when adding a widget in dashboard and iMovie working.




  1. Open Kext Helper b7
  2. Drag natit.kext and appleintelintegratedframebuffer.kext into Kext Helper and type in your password.
  3. Click Install and then restart
  4. Open Kext Helper b7
  5. Drag appleintelgma950.kext into kext helper and type in your password.
  6. Click install and restart.

Installing the Boot loader


Netbook Installer


It is important that you read this carefully. When you install the boot loader, it will have a bunch of options checked for you. If you install it as it is, you will break your system.

What you need to do is make sure that everything is unchecked except for the Chameleon Boot loader itself.

Fixing Track pad




  1. Go to /Extra/Extensions and delete VoodooPS2Controller.kext. You can alternatively search for the kext, and choose Show All and then right click the kext and choose Move to Trash.
  2. Open Kext Helper b7
  3. Drag AppleACPIPS2Nub.kext and ApplePS2Controller.kext in Kext Helper and type your password.
  4. Click install
  5. From the root folder, go to Library/Preferencepanes and place the included Trackpad.prefpane in that folder.
  6. Restart into the other Mac Partition or iAtkos Installer and go to Disk Utility.
  7. Repair the disk permissions and then restart back into the Mac Partition where you installed the kexts.

Fixing Battery




Install the kext with Kext Utility or Kext Helper b7. Repair permissions in the other Mac installation or Mac installer using Disk Utility if reboot proves unsuccessful.

If all was successful, you will now have a functioning 10.6.7 machine. Please do let me know if this worked on your Aspire One D250 machine – or other model and what alternations you made to get it to work – if it worked at all. You can leave this feedback in the Feedback section below this article. I do not guarantee success, but if the method is successful, I would like to know.

To install 10.6.8, you can follow the instructions at this post and reinstall the graphics as indicated on this article.
