Sorry if I'm hogging the forum. I just wondered if anyone had come across a really good book on el capitan? There's essential Mac OS: el capitan edition by Kevin Wilson; the missing manual by David Pogue; my mac os by John Ray on Amazon or Walmart. I could really use a Terminal for Dummies book. The help offered by Terminal is obviously written by programmers for programmers. I used to use Command Prompt frequently, albeit in a limited way. There's lot of youtube and web sources, but you can't read them in the tub. And just to complain because bleeping hasn't started a Venting or Complaints forum [I can understand why this might be a risky move], I think HD is a scam. You can't get your dialog boxes and a readable font in sync and most software has not addressed the problem - including the os. I'm not a movie buff, but finally having been forced to get an HD TV I want my old CRT TV back. You guys have all been brainwashed. Which is why I still buy books [besides the tub]; my eyes get tired much quicker squinting at the screen.
