could then wirelessly connect to the other Mac or PC to perform system software installs. Remote Install Mac OS X was released as part of Mac OS X 10.5.2 on February 12, 2008. Support for the Mac mini was added in March 2009, allowing the DVD drive to be replaced with a second hard drive. With the launch of Mac OS X Lion, Apple has omitted Remote Install. A workaround is to enable Target Disk Mode. Sherlock Sherlock, named after fictional detective Sherlock Holmes, is a file and web search tool created by Apple Inc. for the PowerPC-based "classic" Mac OS, introduced with Mac OS 8 as an extension of the Mac OS Finder's file searching capabilities. Like its predecessor (System 7.5's totally revamped 'Find File' app, adapted by Bill Monk from his 'Find Pro' shareware find program[1]), Sherlock searches for local files and file contents, using the same basic indexing code and search logic found in AppleSearch. Sherlock extended the system by enabling the user to search for items through the World Wide Web through a set of plugins which employed existing web search engines. These plugins were written as plain text files, so that it was a simple task for a user to write a Sherlock plugin. Since most of the standard plug-ins for Sherlock provided by Apple itself no longer function, it was officially retired and removed in the release of Mac OS X 10.5 Leopard in 2007. Software Update In Mac OS 9 and early versions of Mac OS X, Software Update was a standalone tool. The program was part of the CoreServices in OS X. It could automatically inform users of new updates (with new features and bug and security fixes) to the operating system, applications, device drivers, and firmware. All updates required the user to enter their administrative password and some required a system restart. It could be set to check for updates daily, weekly, monthly, or not at all; in addition, it could download and store the associated .pkg file (the same type used by Installer) to be installed at a later date, and it maintained a history of installed updates. Starting with Mac OS X 10.5 Leopard, updates that required a reboot logged out the user prior to installation and automatically restarted the computer when complete. In earlier versions of OS X, the updates were installed, but critical files were not replaced
