The DVD drive in my MacBook Pro is really flaky. It can read and write video DVDs just fine, but for some reason, it can’t read software DVDs.

So, when I needed to install an OS upgrade, I needed to find another way to do it. I had previously installed some software by putting the disk in my wife’s Mac and then mounting the disk over the network. I read that that method would not work in this case, plus it would probably take forever.
