Mac OS X Tiger (version 10.4) is the fifth major release of Mac OS X (now named macOS), Apple's desktop and server operating system for Mac computers. Tiger was released to the public on April 29, 2005 for US $129.95 as the successor to Mac OS X 10.3 Panther. Some of the new features included a fast searching system called Spotlight, a new version of the Safari web browser, Dashboard, a new 'Unified' theme, and improved support for 64-bit addressing on Power Mac G5s. Mac OS X 10.4 Tiger shocked executives at Microsoft by offering a number of features, such as fast file searching and improved graphics processing, that Microsoft had spent several years struggling to add to Windows with acceptable performance.
