Looks like I won't be able to air drop from iPhone to Mac either.

Boy I've got what I consider pretty modern hardware and I'm right on the cusp for some features.

I think Apple is in the final stages of determining if it is worthwhile continuing to develop new versions of OS X and sell computers. You people need to buy more computers! (they gave up on people like me years ago)

This will probably be the last upgrade that supports my early 2008 Mac Pro.

What I've been noticing is computers are becoming more complementary to phones a tablets, whereas just a few years ago the opposite was true.

Macs aren't going anywhere anytime soon, but their development may continue to slow as more resources are put into mobile development.

Looks like 17" MBP models are SOL on many features. ::o

For now, I'm stuck on Lion, that'd be 10.4 (?).

Lion would be 10.7; 10.4 was Tiger
