Wow! Are you guys actually filming season two of Silicon Valley, am I being punked? I'm going to ignore the silly suggestion (sorry that was judgmental, no offense), that The name of one of America's Greatest Parks along with Yellowstone, and The Grand Canyon, could be a mistake to name Apple's finest OS to date, is truly, not true. It's a Native American name. Miwok (a Penutian language) joṣ˙eʾ-HmetiH, lit., means; there are killers among them. But don't be afraid of this Park, be inspired because If the Earth has a church, this is it;
Yosemite Nature Notes - Yosemite National Park (U.S. National Park Service) There are even WiFi kiosks!
But speaking of being fearless, and getting back to the original discussion; The Apple OS Beta; Yosemite, is BY FAR THE MOST AMAZING, MOST STABLE, OS BAR NONE, I HAVE EVER USED IN 25 YEARS! I've been really hard pressed to find anything for Apple to fix. So far the only thing I've run into is I can't pull up the force quit app, but i can force quit from the app bar at the bottom of my screen and I cannot get the OS to shut down, without a cold restart. Those are minor issues for a beta as far as I'm concerned. None of the real fears i had, like running into apps that wouldn't function in Yosemite, that worked in mavericks, or anything else that has in any way lost any of my data or interfered with my day to day use of my computer, in fact it's a huge improvement! If your a beta tester and you're afraid, I say go for it, you're missing a lot of fun!
