Hello everyone,
I had a T440s and was able to install Yosemite on it, but now I got a T450s as a replacement, and I'm having quite a hard time setting it up. I've seen two relevant threads already (http://www.tonymacx86.com/yosemite-laptop-support/164005-installing-yosemite-lenovo-t450s.html) (http://www.tonymacx86.com/yosemite-...hd-graphics-5500-os-x-yosemite-10-10-3-a.html), and the only thing that I have not tried was the BIOS patch. But the interesting thing is: When I use the HD from my T440s as an external HD, Yosemite runs very well. If I try to boot Yosemite from any other media it will throw me a kernel panic.
Could anyone shed a light on this? I am not against trying the patch, but I can't understand why the external HD is working without it.
Kernel panic on trying to boot installer:
Messages on initialization of external HD implying that the driver got loaded ([IGPU] lines):
I've attached my Clover folder; the panic logs, when booted with Legacy support and without; and the external HD's IOReg.
Thank you all for your time and help in advance.
