In addition to showing you a neat cartoon illustration of each OS X version’s nickname, the guide also breaks down the key additions that Apple added with each new iteration.

Jaguar, for instance, we the first version of OS X to include iChat and Address Book, while Panther brought Apple’s Safari browser on board for the first time in 2003. 2007, meanwhile, added support for 64-bit applications for the first time with Leopard, while iCloud made its debut on OS X in 2011 with the release of Lion.

Apple stopped using giant felines to name OS X in 2013 when it launched Mavericks, a convention that it upheld this year with the launch of Yosemite.

Taken as a whole, the guide shows how OS X has really been through a long evolution to get to where it is today. Check it out by clicking the source link below.
