A complete beginners guide to install Mac OS X on a Sony Vaio SZ7
First of all I will start off with: Thank you Mac Community and Insanely Mac! Different files that I will talk about are all work of others, I am just putting the whole thing together, as I don’t think that everybody should be researching as hard as I was.
Please don’t hold me responsible for any issues you may encounter!
Now my laptop is a Vaio SZ780 Configured:
2.50 Ghz
4 GB Ram DDR2
….
Step 1: Partitioning of the HDD
Well you could select any partitioning program, however know this: all your DATA will be lost, if you don’t back up. I used Disk Utility that came with the Installer Disk.
Make sure one of the Partitions is formatted in HFS+ (Journaled)
Step 2: The Image
Now this step is important. Because the only image to use is Leo4All 10.5.2. I have tried several others, but always the same problem: The Screen goes black as the internal LCD is not recognized.
Step 3: Installation
Ok this process is important as this requires a lot of patience. Seclect continue and then just before it says install hit Customised. Try to select minimal drivers. Keep the DEFAULT kernel that is selected. Don’t select any chipset or Ethernet or Sound Drivers. In fact the only drivers you have to select are the Nvidia ones to make the internal screen work. Select 10.5.2 KEXTs and NvidiaGo. Those two and no more.
Step 4: Errors
Mode: SEEPD
Looking out for errors when the computer reboots. Do that by adding –v to the booting option. Everything should boot up fine.
Step 5: Customize
I know the first issue you will have to deal with is the resolution and there is a really easy way to fix it.
Simply add a <String>"Graphics Mode"="1280x800x60"</String> under Kernel Flags in com.apple.Boot.plist in /Library/Preferences/SystemConfiguration
Then go to Disk Utility and repair Permissions. This will fix the issue with resolution in SPEED Mode
Note: Resolutions in Stamina Mode will always be smaller.
Step 6: Various Drivers
How do we get Stamina Mode working? This is very easy. Go to /System/Library/Extensions and delete the IntelGMA* kexts.
Now your able to boot into Stamina mode with 64 MB shared memory but no QE/CI.
Ethernet: I got this working because of a member called Titan and his Kext. Thank You! Simply use kext helper to install the provided kext
Click to view attachment
Sound: Click to view attachment Simply drag it into HDAPATCHER 1.16 and then drag the HDAEnabler.kext into Kext Helper!
Step 7: Important
If you choose to use Nvinject then the internal screen is gone.
You cannot mute the sound entirly!
Step 8: Help Me!
As it took me a while to figure everything out as i am quite new to the scene (7 days). now could you please help me to fined QE/CI support for the X3100? without the screen going all weird. And the Nvidia 8400m gs? anyoen got that working?
Then one more request: anyone got any further with the the Wireless Lan?
Cheers
Hope this guide helps evveryone who wants to install MacOs X on such a beautiful laptop! hehe
