Mac OS 10.5.6 on the Samsung NC10
Well, good news and bad here…
The good news is that, with the DSDT fix (although in all honesty I’ve not tried without) the 10.5.6 upgrade does the right thing and reboots correctly. Even better, a modified SystemConfiguration is no longer needed in /System/Library. May be due to this, the screen is also no longer stuck at full brightness… although due to the following issue, I don’t know whether it can be modified.
The bad news is that neither of the ApplePS2 replacement kexts I have load correctly, and so I’m stuck using a USB mouse and keyboard 🙁
More as I discover it…

When I was trying out various different kernel extensions, I found that there was one (possibly one of the Power Management/SpeedStep/EIST extensions, but I think probably one of the ACPI ones) which caused this exact problem: I advise trying different extensions if you can.
I’ve just created an archive of my EFI partition, which you’ll now be able to find on the downloads page.
Note that the UUID value in Library/Preferences/SystemConfiguration/com.apple.Boot.plist on the EFI partition will have to be commented out, removed, or corrected for the target system.

hello,
I’ve been following this thread, as well as the mysticus one in insanelymac for a while. here is what i did,
Installed a retail copy from an existing working installation of leopard on my desktop, updated to 10.5.6, installed chameleon bootloader, and from installed a bunch of kexts from “bike town” that were in a package for the NC10.
What I’ve been trying to do is getting the original video kext to work by modifying it and not having to use the natit.kext file. I read that you were able to do this. What advantages does this have? better video support? better VGA out support, more stable system? one less unneeded kext to load? I would like to try this.
What power management kext are u currently using? i’ve used the voodoo power kext, but as other have said, it can cause the system to crash, and in my case the system would freeze every once in a while, for about 2 seconds, and then it would be fine.
Another thing, what do you see for battery life with your current set up? with the unstable voodoo kext i get about 6 hours, on the lowest brightness with minimal internet browsing.
I’ve also noticed that my trackpad is not mapped in proportion to the size of the screen. for example, when moving my finger from top to botom causes the mouse to move vertically accross the whole screen, but moving it from sideways, causes the mouse to move only half way of the screen width, causing me to have to lift my finger and swipe again to complete one horizontal travel. It doesnt sound like much, but it leads to unpredictable mouse speed.
What other things have you discovered? at what point are you with your installation.
Any input would be awesome.
thanks

The trackpad mapping is off, and I’ve not come up with a decent fix for this yet. I’ve read of people having luck with FFScroll (as I think it’s called) but I tried an older version this a while ago and it didn’t work – and I’ve not looked again since.
I’m not actually using any specific power management extension – and with the screen brightness set to 25 but browsing all day on Wifi and doing Xcode development gets me between 6 and 8 hours… but I have replaced the internal disc with an SSD. I haven’t had any problems with instability or sleep.
The main advantage of using EFI strings is that it requires one less hacked kernel extension. Since it uses the system driver, it won’t make any difference to VGA out (which I’ve not tried) or stability (which I’ve not actually had any problems with). The strings needed are documented in this post.

Thank you for your reply,
I will look into using efi strings for video, that’s how i have it on my desktop (Nvidia 8800 GT)
I also changed my stock HDD for a 320 GB WD black edition, its the one that spins at 7200, I guess this impacts battery life on one way or another. But 8 hours without any power management sounds incredible!
I will try to get an SSD drive at some point in the future, when prices drop a little more.
I know there is a fix in the works from voodoo for the audio, but i haven’t seen any updates in over a month, have you been able to use ur internal mic? discovered any work arounds?
when firing up photobooth, i cant see the whole window, because of the limited vertical resilution, I know im only missing the bottome portion that shows the pictures taken, no big deal. But i was wondering is there was a way to change the resolution at which photobooth previews the webcam, so i can make it smaller and see the whole thing. This can be done in regular windows computer by changing the resolution of the camera. any ideas?
thanks.

You can alter the scaling factor that OS X applies on a per-application basis – read more here.
The post below that links to an audio switcher which works with the NC10 – but this doesn’t affect the microphone, unfortunately. USB and Bluetooth microphones work correctly right now, but it looks as if the integrated one will have to wait until at least the Voodoo audio driver release.

One last thing,
I cant get the video strings installation to work. Can you please describe how you did this? i see that you point at the com.apple.boot.plist and pasting the string you have above, i’ve tried this, but i couldnt get it to work.
Can you please tell me how to do the strings? or point me in the right direction, i too dont want to have the natit.kext there.
thanks!

If anyone’s interested I have ended up with a partition running OSX.5.6 very nicely on a bog standard NC10 that still has the ‘factory’ settings (i.e. Recovery and Windows Partitions still intact). and I can boot freely between Windows and Mac using a USB bootloader ‘dongle’ to get into Mac. This was done on a FAT32 partition without reformatting the HD to accommodate GUID.
It was done using the various tools and advice that are floating around for Dell and Wind and a Leopard 10.5.4 Upgrade disk (not the recommended Retail disk that didn’t work for me). USB, onboard keyboard, trackpad and speaker as well as Bluetooth work and the usual suspects don’t (ethernet, wifi, headphone and microphone).
Being a total novice I have done nothing using command lines or console and I am deeply indebted to all the advice and gizmos that I have picked up from sites such as this one and the wonderful people who put all the knowledge and effort out there., particularly as they gave me the guts to give it a go…..

Hi Stuart,
I am trying to run OSx86 10.5.6 and using all-in-one motherboard with built-in video chip G33 (GMA3100) running Intel D2C cpu 2.66GHz. I face the problem that I cannot boot up the desktop. I just got the pending greyscreen with bitten apple. Heard that from some websites they claim we can change GMA3100 (no driver provided) to GMA950 in order to bring it up. I tried to use the method you suggested above but it still fails. Could you kindly provide some more help please?

Hi,
I have question concerning my netbook. I am very proud to be the owner of a Samsung N310. But I am having problems getting OS X86 installed…The Hardware specs of the N310 are actually almost 100% identical with the NC10. Now I am trying to dual boot IDeneb 1.4 with the Windows on the Harddrive. During installation I choose the NC10 option in the Customise Window and start the install. The Leopard DVD check and the installation run through cleanly and it goes into reboot. Now i eject IDeneb from my external DVD Drive and the bootloader appears. I choose the Leopard installation and the Apple appears and the spinning circle and eventually gets stuck. Booting in -v mode showed that it got stuck at the AppleDecrypt file. What does that mean? I tried reinstall twice….same procedure….same result..mactually makes sense. Do I have to choose a certain driver during installation? Does anyone have a clue what Icould be doing wrong?
