Umm... Specs? No specs, no help.

And why the quote? It's not needed. It just makes the post confusing to read.

ok sorry

 

update i installed ideneb v1.3 10.5.5 and all installed and boots ok. however i have no Ethernet (greyed out box) or sound.

 

had to do the .AppleSetupDone trick to get past the post-installer. Is there a .kext floating around to help out for the ethernet and sound please.

 

specs are

 

4GB ram, Intel i7-720QM Quad Core, duel ATI Radeon HD 4870 Graphics, i think its IDT 92HD73C1 for onboard audio. and onboard lan is Intel 825xxx series.

 

thankyou

 

another update.

 

got my Ethernet working by trying a different Ethernet kext.

 

just need to sort out sound now tryed about 4 different kexts ( appleHDA, HDAenabler, legacyHDA & voodooHDA) still no sound through internal speakers.

 

 

 

system profiler says
