Hi OSX-2012... about Broadcom, I bought it on ebay and change the orginal one (Intel). Obviously, this kind of IBM uses a BIOS whitelist check for the Wifi Card. So you need to flash your notebook's firmware with another one patched. After that you could inserted your prefered Broadcom or Atheros Cards. For the patched bios I have used this link: http://forum.notebookreview.com/lenovo-ibm/459591-t61-x61-sata-ii-1-5-gb-s-cap-willing-pay-solution-8.html#post6501443

About T61 http://www.thinkwiki.org/wiki/Category:T61 vs T60 http://www.thinkwiki.org/wiki/Category:T60, they seem to have almost the same hardware except for GPU. The DSDT from my guide may cause problems if applied to a T60 and naturally my KEXT for Intel X3100 too. If the T60 has a GMA950, it's naturally supported by Snow Leopard and Lion (both in 32bit mode). I haven't direct experience with ATI x1300/x1400 so at this moment I can't help you so much, sorry.

Hi OSX-2012


- I noticed some stopping process during installation when you let go the notebook in standby status. In other words you have to move the mouse or the the log window every 3/5 minutes. Sometimes (in other notebook) the installation process notify you that it was not able to complete the installation but in reality it's enough to complete the installation after a new boot.

- About the BIOS update I had to use a 32 bit Windows OS. I have installed a Windows XP 32bit with ALL device driver installed from IBM and than reflashed the BIOS with pathced one. Let me know your errors messagges.

- I don't like Snow Leopard 10.6.8 update. It only "prepare" Snow Leopard to Lion Update OS and for that reason it changes a lot of things (kexts too) without get a realistic better improvments. So if you can, forget 10.6.8!!!! Stop at 10.6.7.

- What kind of Graphics Card has the IBM T61 7661-E26? Intel X3100


- At the end what it's working on it? What kind of Graphics Card has it, GMA950 or ATIX1300 or X1400?

- Some BIOS patched can be found here: http://forums.mydigitallife.info/threads/5866-LENOVO-(IBM)-Bioses-especially-Thinkpad?p=534514&viewfull=1#post534514 or here http://www.mediafire.com/?sp1l11i1xpsiw41. It seems that the lenovo BIOS it's indipendent from the Graphics onboard Cards but I invite you to do a better search on google.

My 2 cents

Must I change the three files from the extra or can I change the whole extra file?

like your advice.

The t60 have GMA950 graphics.

When I first install 10.6 I tested a dvd it workes fine with no audio.

Must I install them the grafik kexte in the osx, when its worked why must I

Change something??

IBM says I have Lenovo ThinkPad T61 7661-E26

I have flashed the fresh Bios and see now in the bios screnn GMA945 950 965 is this OK?

At the moment I can install the 10.6 some Kexte updates ,

I tried about 10-20 times no result for good.

My best regards
