Leopard , fully Mac OS X Leopard 10.5 , is the sixth major version of macOS , Apple's desktop operating system , which was introduced under the name Mac OS X at the time. It followed on Mac OS X Tiger 10.4 and was shipped from October 26, 2007 after it had to be postponed by about half a year due to capacity reasons (for the timely completion of the iPhone mobile phone ).

The biggest innovations, apart from a modernized interface (transparent menu bar, three-dimensional dock with “ stacks ”, virtual work areas “ Spaces ”, uniform layout, new icons) included a new finder with a new sidebar, the “ Cover Flow ” - View, the “ Quick Look ” file preview and the ability to search other computers in the network. A data backup software called Time Machine is also integrated. Boot Camp enables the installation of Microsoft Windows from Windows XP with Service Pack 2 on Apple computers equipped with Intel processors parallel to Mac OS X on a separate partition . Leopard also enables 64-bit operation for applications with a graphical user interface. Other major innovations can also be found in Safari , Mail , iCal , iChat , Preview and Parental Control.

As the first derivative of Berkeley Software Distribution, Leopard is officially allowed to use the brand name “UNIX” (in capital letters or small caps ) because it conforms to the Open Group's single UNIX Specification UNIX 03 .

The last version 10.5.8 was published on August 5, 2009, the successor operating system is called Mac OS X Snow Leopard (version 10.6) and was published on August 28, 2009. Leopard is the last Mac OS X version to support the PowerPC processor. All newer versions only run on Intel Macs.

Features / innovations

Mac OS X 10.5 “Leopard” contains numerous programs that perform frequently used functions. Multimedia applications are almost completely missing from the scope of delivery of the system, but are delivered with the Apple hardware in a program package called iLife . For office applications, Mac OS X only contains the simple word processing program TextEdit and the calendar iCal.

The Classic environment was set with Mac OS X 10.5 "Leopard", so that the virtualization of Mac OS 9 and hence to perform older Macintosh programs so that is no longer possible. However, there are alternative virtualization programs or emulators that also run under Leopard, such as the free SheepShaver .

According to Apple, Mac OS X 10.5 offers over 300 new features compared to 10.4. These include:

User functions

• New Automator to help you create workflows faster
• improved finder with new functions
• Boot Camp , software that installs Microsoft Windows on an Intel Mac
• Animated 3D dock
• Video recording in Photo Booth possible

• Spotlight can now search computers over the network and has calculator functions
• Spaces (multiple virtual workspaces )
• Time Machine
• Mail 3

Developer functions

• Native support for many libraries and frameworks for 64-bit applications
• OpenGL has been updated to the latest version 2.1
• No support for Mac OS Classic applications anymore
• Certification as Unix

System requirements

Apple specifies the following system requirements for Leopard :

• Mac computers with an Intel processor, PowerPC G4 (867 MHz or faster), or G5 processor
• At least 512 MB of RAM
• FireWire (integrated)
• DVD drive for installation
• 9 GB of free space on the hard drive
