The problem I have with any computer is that I, compared to a lot of people, go after learning with a sledge hammer. I am not to easy on pushing the limits to learn. I screwed up the Mac about 4 times until I learned what does and does not work. FSCK was all I had left and I couldn't even make that work. A couple stupid downloads, me, not the downloads, sealed my fate. The bright side is that I had to force myself to study and learn, both here and elsewhere, how to fix what I screwed up. Now I am nearly up to speed and have confidence that I can work on the Mac just like I have on PC's. Sounds a little warped, doesn't it?
Yet, I handle my cameras and lenses like newborns. My enlargers are old yet look new. My wife still tolerates me. Hey, it's all good!
