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

OS X Lion

King of beasts was merely available by purchase and download from the Mac App Store, where it retailed for US$29.99. Yous must haveOs X 10.6 Snow Leopard installed to purchase, download, or install Lion, and the 4 GB download could accept some time with slower DSL connections (we don't even want to think about how long it would take with punch-up). As a convenience, Apple allowed users to bring their Macs to a nearby Apple Store and use Apple tree's WiFi to make the download.

Like Bone X 10.6 Snowfall Leopard, Panthera leo requires an Intel-based Mac, but it goes ii steps across that. Get-go of all, Panthera leo is a 64-bit operating organisation, and so it won't work on those 2006 Macs built around 32-flake Core Solo and Core Duo processors. It requires Cadre ii Duo or newer, which leaves the following Macs backside unless you update the firmware and install a Cadre 2 Duo CPU:

Additionally, Lion is the first version of OS X with no support for PowerPC software. Apple tree introducedRosetta, which lets Intel CPUs run PowerPC apps, withOS X x.four Tiger for the beginning Intel Macs in 2006, and it had been part of Os X until at present.

The concluding version of Lion, Bone X 10.vii.5, was released on Oct 4, 2012. Information technology was the first version of Mac OS X to be part of the annual upgrade program – e'er since Lion, Apple has released a new macOS version every year.

Lion was replaced pastBone Ten 10.eight Mountain King of beasts on July 25, 2012, just a year afterward King of beasts outset became bachelor. Lion is no longer available for purchase through normal App Store channels, although y'all may be able to larn admission to it through Apple tree Back up.

Lion is the oldest version of Bone X impacted by the "goto fail" bug. EncounterApple and the 'goto fail' Issues for information on securing Panthera leo.

Installation Tip

Y'all tin can't just install Lion on whatsoever old Mac that support it. The installer's certificate has expired, and so y'all need to set your Mac to think it'southward operating in the past. Using trial and mistake, I plant that setting a date in 2012 will let the installer function. To alter your Mac's date:

  1. Open up Organization Preferences.
  2. Open up Appointment & Time.
  3. If your Mac is set to Set appointment and time automatically, which is usually the example, disable information technology.
  4. Click on the year and use the down arrow to the correct of it to change the year to 2012.
  5. Install Lion and make several rounds of updates.

After you complete the process, be sure to gear up your Mac to the electric current date and fourth dimension. Enabling the Gear up engagement and fourth dimension automatically setting is the easiest way to do it.

Downloadable Updates

Standalone updates allow y'all update to a newer version of Mac OS X from your difficult drive instead of using Software Update, which requires an Net connection. This can be especially helpful if y'all have more than one Mac that need to have the update installed, since you only have to download it once. Download the one(s) you need and install them after mounting the deejay epitome and launching the Installer plan.

There are two types of Standalone Updates: Private (or Delta) and Philharmonic.

  • Individual Updates update one version of Mac Bone X to the next version. For example, the Mac Bone X x.7.four Update updates Mac Os Ten 10.7.iii to version 10.7.iv. Individual Updates are also known as Delta Updates.
  • Combo Updates update the base of operations version of a Mac OS X release to the version specified in the Combo Update, including all intermediate updates. For example, the Mac Bone X 10.7.4 Combo Update updates any before version of Mac OS 10 ten.7 to Mac OS X 10.7.4 using a single installer, as opposed to installing the individual Mac Os X 10.7.one, 10.seven.two, 10.7.3, and 10.7.iv updates.

Standalone Updates are generally available 24 to 48 hours after the Update is bachelor through Software Update.

If you fire a Standalone Update to CD, its disk epitome must be copied to your desktop or another location on your Mac OS X startup deejay in order to exist installed.
