"If you've upgraded to Yosemite, no doubt you are aware of the many reviews and articles that are available about the new features contained therein. Here is a 50-minute video tutorial that I found helpful," writes Jim Hamm. "Two comments from the reviewer that I take exception to: he mentions that he feels a minimum of 8 GB of RAM is required to run Yosemite. I concur that 8GB would be nice, but by no means necessary. I have 4 GB of RAM and am running Yosemite quite satisfactorily.

"He also believes that Yosemite was released prematurely, and that people should wait about 6 weeks before upgrading. That may or may not be true, but the release is close enough for me. The few bugs I can deal with, and I like experimenting anyway.

"There is one feature that most reviewers think is 'half-baked' or 'buggy' — Handoffs or Continuity. This is where one can be on, say, a website in Safari on your Mac, then go to your iPad or iPhone, and pick up right where you left off."

Jim comments, "I can't tell if this 'tis or tain't' true because I've not been able to enable this on either my Mac or iPad. More research needed here on my part.

"Other than that, the reviewer does a nice job of explaining the nuances of Yosemite. If you've got 50 minutes to spare or invest, sit back, get a cup of coffee, and take a look. Also, you'll note, the website contains many other reviews available."
