Sorry, but after weeks of testing Yosemite and El Capitan, I come to the conclusion that these OS have become nothing more than playgrounds for programming iKids who try deliberately to kill the productivity, reliability and usability which was once a leading standard in times when Snow Leo (for those who werent born at this time: its Mac OS X 10.6.8) for the creative and innoviative community of Apple users. Since then, Apple Inc. has forced its customers using MacPro, MacBook and MacBook Pro machines to adapt to the look and superficial functionality of a communication device, like the iPhone, which is - in fact - a good device for communication. But this is stil the worst case for those who need to work fast, reliable, productive, creative and innovative on Apple machines (as it was before). - Well, as long as you are accustomed to play around (not REALLY being PRODUCTIVE), more on the communicative side, spooling down your WhatsUp and Twitter blah blah, you may not understand what Im trying to exlain. The others of us, who dont like to waste their time for being misused as Beta-testers and being involved in endlessly looking the spinning wheel of colorful death, may already know what Im talking about. - But there is still a solution (well, a painful one for Apple): Sooner or later, governments will crack down on encryption and will get broad access to all kind of data which is actually transferred, collected and used on Apple servers (and other Big Data Companies) ... then, the people will realize that privacy is something which should be kept locally, not in the Cloud ... But this upcoming painful period may lead to the insight, that Apple users should HAVE A CHOICE, means, to keep their workspace and data on their own machine, running apps without spying and grabbing away personal data, but being very reliable, productive and working like a charm, as it was in times of look & feel (not hide & search), just old-school apps like iLife 11, iWork 09 and so on, while on the other hand these Apple users may DECIDE BY THEMSELVES (e.g. clicking a button) whether to surrender their data (or results of productive work) to the Cloud (i.e. whereever those servers may be installed, like Wash. DC, Bruxelles or Peking, and being under suspicious scrutiny of governments ...o:) - To say it briefly: SEPARATE the product lines: ONE line optimized for the old-school creativity, ONE line for the flippy-hippy communicative kids and ONE line for those who want to spread their data and results via the web to others (as a gift for the governments which want to know who might become the next danger for the system ... ;) - Greetings and my best wishes! -Gisela
