Has anyone been able to install the update on Lenovo Y510? I have tried following the following guide:


http://forum.insanelymac.com/index.php?showtopic=109102 with/without



but it hangs completely between 45% and 52%


If you have gotten to update -- please let us know. I would appreciate any help I can get.


System: Lenovo Y510,

Wireless: Intel 4965

Wired: Broadcom 5906

Mem: 2 Gig

HD: 250


On the side note:


when I come to boot screen, I type the following

mach_kernel -v cpus=1 rd=disk1s2


as system starts booting from the USB HDD, I get error message that the boot kernel is different ... (I cant remember

the rest). what is the command to execute the kernel from the USB drive rather than one that is installed on the internal



Thanks in Advance
