skipaq: Think of it like this. You go into a dealership to buy a new car. The salesman says, "Remember, it may not start when you need to go to work each morning. I strongly suggest that you buy a second car just in case." That's the kind of failure I'm referring to.
Joe Holmes: Yep. That checks the integrity of a sparse bundle TM backup file on a network drive.
Brutno: That's exactly why I cited your concern in the "cons" section.
brilor: Thanks for a most informative and gracious response. Theories are made to be tested. Mine was intriguing while it lasted.
John, I am well aware of the F-104's history and limitations. I am a semi-historian of the aircraft. It was used as an editorial example of speed and simplicity without computers - leading to the car analogy. The story about both aircraft cited and how cars will soon to have millions of lines of code is indeed a sobering story. I formed a theory based on some evidence. The interview with Dr. WIltbank, the timing of Swift, the above trend in airframe/carframe code, the concerns over autonomous car safety and finally Mr. Bell (former Boeing) on Apple's board of directors.…
iVoid: Same idea here. Looking into that.
All: A common thread here seems to be Apple's failure of imagination, quantified in ways that aren't typically discussed. Keep those comments coming. There may be a follow-up article brewing.
Old UNIX Guy: I've been using El Capitan for several months now, every day, as my go to production OS, and while I get an occasional lockup, I am generally quite pleased with 10.11. That lockup happened in Yosemite and Mavericks also, likely some deep bug carried forward. I haven't traced it down, but it only happens on the Mac Pro. The MacBook is rock solid, likely because I don't experiment with it. It's hard to believe that Apple would ever do less than its best with OS X. I am not pleased with Apple Mail either. Someday, someone will…
skywatcher: A product "con" in my book is a badly implemented feature, a tragic, missing feature, a really bad bug, a price that's way out of line, or some other reason to consider NOT buying the product. In that sense, I didn't identify any "cons" that say "Don't buy." That said, all software has minor defects, bugs, or features that some people want but don't get.
CudaBoy: How so? Here's just one example of what I'm referring to. http://www.techhive.com/article/2881620/4k-content-protection-will-frustrate-consumers-more-than-pirates-meet-hdcp-22.html To quote: "HDMI 2.0 support, which is also required for TVs and devices to play 4K video, does not guarantee HDCP 2.2 compatibility. In fact, though there are many HDMI 2.0 compliant A/V receivers in stores right now, most do not support the new copy protection." And then, after THAT, one needs HDMI 2.0a to support HDR. But whose version? As I said, what a mess.
