My native notebook keyboard did not work "out of the box".

I downloaded ApplePS2 driver source from Apple's developer site, hacked them a little (added self-test to keyboard enabling method) and my notebook's keyboard (notebook: LG LS50, Centrino (SSE2 only), ATI Radeon M10 (9600)) works almost perfect.

I give no guarantee, that it'll work with your's specific keyboard, but you can try. May be I'll continue to develop this driver. I'm totally newbie to MacOSX developing, so...

How to install:

1. download Click to view attachment
2. unzip
3. copy it to /System/Library/Extensions (something like "cp -R ApplePS2Controller.kext /System/Library/Extensions/" in terminal)
4. modify owner (something like "chown -R root:wheel /System/Library/Extensions/ApplePS2Controller.kext" in terminal)

before entering commands in terminal, switch to superuser mode ("su", press enter and enter password)

Reboot, unplug USB keyboard and enjoy (if you can).

Allright dude! I also have an LG laptop, but LS 70 express model and my keyboard doesn't work too. Thank god that someone developed a patch... Will try patch as soon as get home from work

Hi, I did it, it works awesome and I'm going to gave you step by step Instruction (Del Inspiron 2650)
Native Keyboard and TauchPad Works Flowless

1) Go to HardDisk>Applications>Utilities> (and turn on terminal)
2) (Tupe in Terminal) sundo nano /etc/rc (Push Enter)
3)(It Will Ask you Password: and type in your user pasword and push ENTER)
4)(It Will open rc file and navigation menu on the bottom, push CONTROL+V untill you go to the and of the fille)
5) (Betwan) if [ "${VerboseFlag}" != "-v" ]; then
/usr/libexec/WaitingForLoginWindow
fi

(Line and) exit0 (line insert this code:)

kextunload /System/Library/Extensions/ApplePS2Controller.kext/Contents/PlugIns/ApplePS2Keyboard.kext
kextload /System/Library/Extensions/ApplePS2Controller.kext/Contents/PlugIns/ApplePS2Keyboard.kext
6)(Push CONTROL+O, to activate saving potion, Push CONTROL+T, to activate "save to file option")
7)(navigate down and right in to a fille list untill you find "rc" file, get cursor on top of it and push enter, it'll save changes)
8)(Push Control+X, to exite rc fille)
9)(Tupe in exit in terminal, close terminal and reboot)

Hopefully itll be work
good luck.

Well, a day passed. Driver works normally, without any problems (I work with another drivers now, so I do reboot often and so on). Even display backlight keys works (combinations with Fn key) and volume button works.

If anybody is interested - I've updated one more driver. PCCard now works for me. It's a Texas Instruments chipset. As I remember, TI7620. If anybody needs this updated driver, I can upload it here.

hi,

i have LG W1 and the fix did not work 4 me.

i have found no solution for my computer, so i have decided to create one of my own,
i started reading about apple driver development and iokit related articles, got several keyboard/ps2 source code but i need some hints regurding what to change and play with in order to make it work can you describe a little what was your approh of hacking it?

10x ahead,
Shay.bc.

I spent some more time to create more accurate patch. Now it does not do BAT (keyboard self test), but only sets needed parameters. Also I got rid of annoying messages in system log.

But, in fact new KernelExtension do all the same things.

If your keyboard does not work with this patch - PLEASE, tell me keyboard type/manufacturer/ID/somethingElseToDetermineKeyboard. Type of your notebook, if it's native laptop keyboard.

PS/2 protocol is awfull! But I'll try to write normal driver. Next step will be looking to linux ps/2 drivers.

sorry guys... but i was trying to make it fine. The problem is that the system reload automaticly the permissions as before.
I'll try to explain...
We have a package which is responsible of ps2 devices : ApplePS2Controller.kext, this package contains three kextfile : ApplePS2keyboard, ApplePS2trackpad and ApplePS2mouse.
the problem we have, we have to reload the good version of package with goods permissions.

The package i have is attached here

so now, we have many solutions:
- change the /etc/rc file which will be executed at every boot.
- unload and reload the kext file.

i don't garantee this solutions works fine, but you must try many times for working
the first solutions (under windows):
Download MacDrive
open the file rc in your osx HD and edit it with texteditor (add
"kextunload /System/Library/Extensions/ApplePS2Controller.kext/Contents/Plugins/ApplePS2Keyboard.kext
kextload /System/Library/Extensions/ApplePS2Controller.kext/Contents/Plugins/ApplePS2Keyboard.kext"
at the end of rc file just before "exit 0")
Save and close.
Reboot and tell me


the second solution (under osx):
delete files .mkext .kextcache (2 files normally) in /System/Library/
copy the package .kext i attached into /System/Library/Extensions (you'll need to authenticate so don't forget to load the virtual keybord;))
load this command in terminal (copy it into a textfile and "copy&paste") YOU WILL NEED A ROOT ACCESS!!!

sudo diskutil repairPermissions /
sudo chmod -R 755 /System/Library/Extensions/ApplePS2Controller.kext
sudo chown -R root:wheel /System/Library/Extensions/ApplePS2Controller.kext
kextload /System/Library/Extensions/ApplePS2Controller.kext
kextcache -k /System/Library/Extensions/

ok, let's try it




and if someone comes here and have a better solution WHICH works ...tell us!!
i don't its the best.

I'm using Lenovo 3000 Y310 (7756):
I have try nearly all the PS2Controller.kext but none of them work including your PS2keyboard driver.
So please can you help me to get my Built-in PS2 keyboard work for once.
