I remember when vista was made available and Apple poked the fun out of it in their "M. Mac and M. PC" adds. They took the mockery out of the continuous Vista alerts asking for confirmation. Today, in Mavericks I am more or less doing the same thing. And today, I fell in the trap that we all fall in when there are too many warnings, "we don't read them" and click a button just to move forwards. Unfortunately, that was an alert that was worth while reading. But, hey, I have already read soo many alerts, it starts with those "new software to install", then the "you pulled the usb stick out without eject", then "the file already exists; replace ?", etc. etc. Frankly, I'd much rather do errors myself without OSX enducing me to do errors. And I'd love to kill some of those alerts, they don't add value when they are repetitive. So I truly hope that yosemite has a global "no alerts" switch.
