Mountain Lion OS X 10.8 Launch Day Roundup

Today, Apple launched OS X 10.8 Mountain Lion for $19.99 on the Mac App Store. The latest version OS X provides a number of new features borrowed from iOS as well as some Mac specific ones. This overview video from Apple provides a quick look at the biggest new features.


Other sites have put together more detailed videos showing smaller changes and a more detailed look at AirPlay mirroring.

In general, the reception has been positive amongst reviewers, especially given the $19.99 price tag. The launch, however, has resulted in the removal of OS X Lion from the Mac App Store. While this isn't too big a surprise, it could leave some owners of older Macs stuck if their Mac isn't supported by OS X Mountain Lion but were supported by OS X Lion.

The other major hiccup in today's launch was the distribution of codes for Apple's Up To Date program. The Up To Date program offers Mountain Lion OS X to customers free of charge if they have bought a new Mac since June 11th. Apple seems to be aware of the issue and is working on reissuing faulty codes.

So much faster!

I have an early 2008 iMac and wow I've noticed an increase in speed that I haven't seen since Leopard that was original installed on my iMac. Snow Leopard was quick too but Lion was pretty sluggish. I can't get over how fast Sarfari is now too, super quick! Good job Apple. :)

For $20 Mountain Lion is 100% worth it.

Another thing I like about Mountain Lion is that now it doesn't "auto save" and there seems to be less of a focus on the "Resume" feature.
