Hi Fubo,

You are not the first to have this issue but i don't know how to fix it, could you give us more details about your system and hardware please, and also can you type 

sudo kextstat

and 

sudo dmesg

in Terminal and post the results (in zipped .text please)

 

 

:P And all the other users with this crash issue should do the same in order to find what goes wrong

 

 

Cheers :D

here it is my system information,thank you agian...

 

 

Hello fubo, did you tried to edit the kext to have your own macaddress? if yes, maybe you did some errors and i suggest you to download again and use the kext as it is to see if it works for you.

On the other hand, if you are trying the kext as it is and it crash on load there's not so much we can do,maybe some other components or driver of your pc are not compatible, the kext is not configurable either not require special skills to install, just kexthelper is fine. I don't know all laptops in the market, i've seen a lenovo model where the wired card is not powered on by default and there is a switch on the front part to select wired or wireless card, as last resort try to initialize the card booting windows first, then restarting using macos.

 

if you are in trouble and want to remove the kext, press F8 at the start and then write -s when it ask for a command, the system will start in single mode,console only,from the console mount the filesystem "/sbin/mount -uw /" then rm -r /System/Library/Extensions/AppleBCM5787MEthernet.kext followed by rm /System/Library/Extensions.mkext

 

then reboot

thanks,bodies.

 

maybe the sequence is wrong?

first,i,removed other bcm5701 and bcm5751 text,then changed my macaddress,next installed the bcm5787text with kext helper.and then got a information,"cross your finger,and reboot","network preference to set...",but,seconds after,it freeze,even i can't start os any more.

by the way,how to start promiscuous mode?

Try without removing bcm5701 and bcm5751, if you did not tweak in them keep them in their place, I always keep them and it works...

DON'T TOUCH AND DON'T REMOVE the BCM5701/51 kext, keep them in their original place and don't modify them, (may be if you tried other tricks before this kext are modified ? try to find the vanillia one), install BCM5787M with kexthelper, repair permissions...

i repaired permissions with disk unities,however,still can not log into mac os...

 

 

Anyone else with a Thinkpad report success???? maybe it just not work on that machines.

 

@Kenny, if the system don't start even with -s switch you need to boot from dvd and when you get the installation screen look in menus and choose Console, from console type cd /Volumes/YOURHDNAME/System/Library/Extensions then

 

rm -rf AppleBCM5787MEthernet.kext

Thanks Benny134!!

 

First I installed this kext : Broadcom5787M.zip

More info here HERE

 

Then I installed this pack : PCCard.10.5.2.Beta2.pkg.zip

 

Now my Ethernet Card started to be recognized by the system.

Then I used this comand line: tcpdump -i en0

 

That´s it!!! It´s working now!!

Hi guys,

great work you are doing here, thanks...

 

I have a problem with this BCM5787M on OS X 10.5.6, it freezes my system almost instantly. When I boot with -s to remove it i gives me panic and freezes again so i cant boot in my system. It worked excellent on my iAtkos v5i 10.5.5. although sleep stopped working. But then i did clean install, updated to 10.5.6. tried this kext and it freezes.

I see that nobb1x is also runung 10.5.6 and BCM5787M so maybe i should do something more.

I would appreciate any help.

Thanks again...

Yes, I have a Lenovo R61i with the BCM5787M network chip/card.

I followed the readme to a 't', meaning EXACTLY every step. Wired networking is great with a manually defined network setup.

I used manual setup for ip, router, dns, search domain. Once I did that, all was fine.

 

As with others, I am eagerly awaiting the wireless solution. But, great work to all the guys who put in so much effort!

I have a r61i, not an r61e. Not sure that matters, but I wanted to highlight that.

I followed the readme included in the zip file at the top of this thread.

Did you:

sudo chmod -R 755 /Library/StartupItems/Start_Promisc

sudo chown -R root:wheel /Library/StartupItems/Start_Promisc

?

Also do you see output with 'sudo tcpdump -i enX' where X is the number of your BCM interface?

This will allow you to see if there is traffic on the interface indicating it is working. If you see traffic of the type that makes you believe it is working, then check very carefully your network settings. I had to set mine manually as I've mentioned.
