Ok, thanks for your help so far. Will try your boot pack. 

Thanks Hervé, this explains a lot. I'm just trying to resolve the video issues I'm having - lags when playing video clips, no video on mkv, choppy/messed controls etc. Apart from that my dell is working grand with sleep, Atheros card (after adding atheros kext). I haven't tried Ethernet yet.

Ok, so I created my own SSDT and DDST. 

 

Are there any particular patches I should apply to my DDST?

I'm still having issues with playing .mkv files.

 

Cheers

Hey there,

 

I have followed your guide and managed to install 10.9.4 on my E6420. Thanks for the guide and files BTW

 

I have one problem though. When I play any mkv file in vlc I'm getting no video. I assume it is a problem with HD3000 and gl/cl acceleration. Any advice?

 

Specs:

E6420 A21

i5-2540m

HD3000 with 1366x768 (0126:8086 rev 09)

 

Thanks!
