    @Tluck, I just wanted to thank you — you did amazing work! T420 is still, even after all those years, an excellent laptop with macOS.

    Lenovo ThinkPad T420 with UEFI Only

    Hi, I had no problems with graphics after update (I updated from 10.11.0 to 10.11.4 via combo updater). But I had a problem with sound. The AppleHda wrapper didn't work for me - had no audio output to select and grey sound icon. I had to use VooodooHDA, which works, but with limitations (it doesn't recognize when you plug in headphones). The machine is plain T420 with Intel HD3000, 4GB RAM and Ericsson broadband modem (which actually works, I even managed to modify crappy Apple WWAN interface to recognize it). Overall great work, thanks to tluck I have much better machine than original macbook (more ports, two hard drives etc) and very, very stable.
