What? I have to post before posting??
Hello, I joined this forum because I've found a post presenting the same problems that I am currently having with my Mac book.
I have found a lot of useful information on this forum in the past while experimenting with various Linux distributions, but have not bothered to sign up. But here I am now, and I'm ready to contribute if I can.
Thanks to all of the veterans who have unknowingly answered my questions in the past, and thanks in advance to everyone else!
