Recommended Posts

How are you?


I really need your help for my problems!!!


Recently, I tried to install Mac OS 10.4.8 on my laptop “IBM-Lenovo Z61m”, Every device work probably, but I had some difficulties on the following devices that I think they are very important, by the way, the devices are:


1. Broadcom NetExtrem Gigabyte Ethernet BDM5750A with ID= 14e4:1601 “Very Important Issue”


2. SoundMax Integrated Digital HD.


3. Intel® pro/wireless 3945G.


I tried firstly, before I write any question for you, to search about available solution, especially for 1., on the web, and I tried many of them for solving Ethernet card, like:










Infortunatliy, neither any solutions work to me I get this message,


“ifconfig: ioctl (SIOCAIFADDR): Network is down :”


When I tried modifying the mac address of my adapter.


Please, if anyone have any perfectly or ablicable solution to work at least Ethernet card or all problems
