OS X 10.vii Lion was released on July 20, 2011 and made some huge changes to the Mac. Some of these changes were to brand information technology easier for iPhone, iPad, and iPod touch users to adapt to the Mac, some to make the two platforms piece of work ameliorate together, and some to go on making the Mac better and better.

OS X Lion

Lion was only bachelor by purchase and download from the Mac App Store, where it retailed for US$29.99. Yous must takeBone Ten ten.6 Snow Leopard installed to purchase, download, or install Panthera leo, and the 4 GB download could have some time with slower DSL connections (we don't fifty-fifty want to call up well-nigh how long it would accept with punch-up). As a convenience, Apple tree allowed users to bring their Macs to a nearby Apple Shop and use Apple'due south WiFi to make the download.

Like Bone X x.vi Snow Leopard, Lion requires an Intel-based Mac, simply it goes two steps beyond that. Outset of all, Lion is a 64-fleck operating system, so it won't work on those 2006 Macs congenital effectually 32-scrap Core Solo and Cadre Duo processors. Information technology requires Core 2 Duo or newer, which leaves the following Macs backside unless you lot update the firmware and install a Core 2 Duo CPU:

Additionally, King of beasts is the first version of OS 10 with no support for PowerPC software. Apple introducedRosetta, which lets Intel CPUs run PowerPC apps, withOS 10 10.4 Tiger for the showtime Intel Macs in 2006, and it had been office of OS Ten until now.

The last version of Panthera leo, Bone X x.vii.5, was released on October 4, 2012. It was the first version of Mac OS X to be role of the annual upgrade program – ever since Lion, Apple has released a new macOS version every year.

Lion was replaced byOS Ten ten.8 Mountain Lion on July 25, 2012, simply a year after King of beasts first became bachelor. King of beasts is no longer available for buy through normal App Shop channels, although yous may be able to acquire access to it through Apple Back up.

Panthera leo is the oldest version of Os X impacted past the "goto fail" bug. Run acrossApple tree and the 'goto fail' Problems for information on securing Lion.
