Hello,
I'm sure you are, more used to getting bad news posts, when people have trouble. And my situation began that way. I'm the one with the recent Chicken and Egg Issue, helping a friend install Debian 9.4 on an expired MacBook, which Apple states can't run anything later than OSX Lion. The Broadcom B43 issue temporarily prevented me from having this Friend's Macbook connect to the Internet. The Debian 9.4 CD1 Installed well (after I got past EFI issues, with the help of refind), but I couldn't connect to the Internet, due to the Wifi issue.
Many Thanks to Abdullah Ramazankgoglu, Rick Thomas, David Christensen, Dan Ritter, Tomas, Brian and Eike for your help. The Firmware installed correctly, and I have a happy friend, with a "Rehabilitated MacBook.
Isn't this what this is all about? I now have a happy Debian user, who was previously a marginalized Mac user, down on his luck, and unable to afford the expensive new Macs!
Now, he is up to date, and able to use Firefox, LibreOffice, and other Debian Packages, while also able to Dual Boot, back to OSX Lion, when he needs to. How's that for Volunteer work?
Thank you and best regards,
Kenneth Parker
