Os Ten x.7 Lion was released on July 20, 2011 and made some huge changes to the Mac. Some of these changes were to make it easier for iPhone, iPad, and iPod touch users to adapt to the Mac, some to brand the 2 platforms work better together, and some to keep making the Mac improve and better.

OS X Lion

Panthera leo was only available by purchase and download from the Mac App Store, where information technology retailed for US$29.99. Y'all must acceptOS Ten x.6 Snow Leopard installed to purchase, download, or install Lion, and the 4 GB download could take some time with slower DSL connections (nosotros don't even want to think near how long information technology would accept with dial-upward). As a convenience, Apple tree immune users to bring their Macs to a nearby Apple Store and use Apple'southward WiFi to make the download.

Like OS X 10.half-dozen Snowfall Leopard, Lion requires an Intel-based Mac, but it goes ii steps beyond that. First of all, Lion is a 64-bit operating system, so it won't work on those 2006 Macs built around 32-bit Core Solo and Cadre Duo processors. Information technology requires Core 2 Duo or newer, which leaves the following Macs behind unless you update the firmware and install a Core ii Duo CPU:

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

The last version of Panthera leo, OS X x.7.5, was released on October four, 2012. It was the starting time version of Mac Os X to be role of the annual upgrade programme – ever since Lion, Apple has released a new macOS version every year.

Panthera leo was replaced pastBone Ten 10.8 Mountain Lion on July 25, 2012, but a year later Lion outset became bachelor. Panthera leo is no longer available for purchase through normal App Store channels, although you may be able to larn access to it through Apple Support.
