Installing Snow Leopard on ThinkPad X61

[Pitrako]

Hi all !!!

I have my X61s with SL 10.6.2 and I have some minor issues, may you can help me to fix it.

Sleep doesn´t works, if I close the screen, laptop seems to going to sleep, the moon led lits, but if I open the screen, don´t happens nothing and if I press the on button seems to start the laptop but nothing in screen, I have to press the on button for 4 or 5 seconds to restart.

The middle button of the trackpoint only works in Firefox, if I press it then I can scroll with the trackpoint, in Safari act like the third button and when I press it over a link then open a new tab with the link I pressed. Is possible to configure the third button in Safari for act like in Firefox???.

In the Mouse properties in System preferences don´t appears the third button for configure.

Well I hope you can help with that issues.

Regards

lol, you don't get the point, CeleronPopsicle. It's for people who already own ThinkPad X61. Buying X61 just for the purpose of installing Snow Leo would be ridiculous.

Great thread. I'm a complete OSX with a tad of Linux knowledge. So I was looking for something that was rather "idiot-proof". Well, I've found it!

Thanks Sammys. And ofcourse all the other guys. This has saved me alot of time all together (instructions + correct Kexts).

Now, on to the next step -- dual booting SL/W7.

Wow, this is a great thread. I'd more or less given up on using my X61 for OSX, but following Sammy's instructions for 10.6.3, things are working pretty well. A few questions though:
1) Has anybody managed to get Atheros wireless working with K64? It doesn't seem to load for me.
2) Any suggestions for a battery meter that will work with VoodooPowerMini?
3) There's something a bit peculiar going on with the built-in LCD. Colors seem unusually purple. For a maybe 1/2 a second, the blue OS X background looks correct on booting, and then it turns purplish. Any ideas, or monitor profiles to work around this?

Thanks!

Hi,

This is a great instruction. I'm very tempted to install snow leopard on my x61 now.
Just wondering what kind of battery life are people getting?

Cheers,

I use an EFI String combined with the AppleIntelX3100FB.kext vers. 1.5.18 and i have proper brightness control.

By the way, i got Vanilla speedstepping working too, and many other fixes in my dsdt.

Eager to get your X61 laptop updated with Snow Leopard 10.6.4? This is for you! Here are the steps:

1. Download the OSX 10.6.4 Update and the new kext bundle (attached).
2. Mount it and double-click the .pkg inside.
3. Run the installation as you would normally.
4. After it has finished don't click the restart button. Instead, open a terminal and type:
   

   sudo rm /System/Library/Extensions/SleepEnabler.kext

5. Copy the SleepEnabler.kext from the bundle, wait for OSX to finish updating the kext caches (you can see this happen if you watch All Messages in Console).
6. Reboot to 10.6.4 using the -f kernel switch in Chameleon (just to make sure ).

Remember to backup your installation before doing this!

This kext bundle has an updated DSDT that now allows the AppleHDA kext to stay in place and vanilla. Happy times.

Known issues:

• SDHC card insertion locks up the system (untested since 10.6.2). No workaround yet.
• Sleep and radio disable switch result in bluetooth being unavailable in subsequent boots. Boot to Linux or Windows to bring bluetooth chip back online. Might be fixable with a DSDT change.
• Display brightness is uneven when not at 95% or 100%. Only workaround is to install non-vanilla framebuffer kext as shown in previous post by @grandflash. More about the solution by @grandflash et al next.

Have fun with the update!
Notes about solution referenced and provided by @grandflash
I actually started my X61 OSX days using a hybrid mix of SnowOSX and the solution described by @grandflash. I read that @grandflash had done some amazing work on getting OSX running on non-Apple hardware so I was glad to find their solutions did work. Unfortunately, the solutions stop the install being Vanilla for the following reasons (there could be more):

• AppleHDA must be disabled. You can do this using the command shown in the 10.6.3 instructions earlier in this thread.
• AppleIntelX3100FB.kext must be replaced with an earlier version of it that has been patched.

Another thing to note about everything referenced by @grandflash. The DSDT is not for an X61 but instead for either an X61s or X61 Tablet. Also, I can't recall if some speedstep customizations are placed both in the DSDT and the LegacyX61*.kext or just in the legacy kext. Whatever the case, DO NOT use the Legacy X61*.kext from the post referenced by @grandflash if you have an X61 (without 's' or 'tablet') as speedstep customizations are hardware specific (CPU-specific to be precise). I have been building a legacy kext for my X61 (7676-3PM) but it has been slow going. I will definitely post it here when it's ready.

So by all means use the solution provided by @grandflash but be aware of the above notes.

Hi, Grandflash, I couldn't find your dsdt.aml anywhere. Would it be possible for you to post it? I assume it is for x61s? I have pretty everything else working except speedstep, sleep and restart. Thanks a lot.

@mightycrown: Not sure about bluetooth wakeup and my X61 is showing CPU clock speed lower than it is meant to be. System still works and I can Mac it up. It's a low priority for me to fix that. In my spare time, which there isn't much of right now, I've been working on speedstep. It's a little hit and miss because it is specific to the CPU. Hopefully I'll be able to get it working sometime soon so it can run on batteries more efficiently.
