  1. Lenovo ThinkPad T420 with UEFI Only

    Hi guys. I have a t420 on 10.8.5, which has been running perfectly for months now (well, you know, except for sleep, hardware buttons, etc). Would I be able to update to Mavericks directly, in-system? Would it boot afterwards so I can replace the necessary kexts, ect? Or do I NEED to create a Mavericks usb? Has anyone tried a direct update and succeeded?

    Thanks! I ended up using raffitaffy's dsdt from post #51 and now I have sound! I will continue poking and will surely come back with more questions!

    Hi, Kogen. First of all, thank you so much for your work. This is my first time using OSX and it's all thank to you! I've been busy these past days with my t420 (OEM 4236) until I finally got it up and running, with sleep, sound, wifi via usb adapter and all! Well, that was the good part. The bad part is that, due to stubborn nature, I then erased the disk and reinstalled it again from scratch to check whether I had understood or not (I know, I know). As it turns out, I didn't, so I don't have sound at all. I've tried everything, starting with the file you mentioned in post #30, to no avail. So I turn to you. Attached you'll find my darwin dump; I'd be very grateful if you could take a look and maybe help me. DarwinDumper_2.6.5_Lenovo_ML_manueljaime.zip
