HEADS UP
Because of my penchant for testing software, I upgrade/update frequently. On three recent occasions when the update/upgrade completed my login password failed to work. It wasn't until the third time I figured out what was happening - the keyboard had switched to another language. The fix was simple, just click on the language flag on the menu bar and change it back to English. I wish I had figured this out sooner it would have saved me many hours of near panic, several reinstalls, and a lot of work correcting things.
