Editing Mac OS X Tiger (section)

==System requirements==
Mac OS X 10.4 Tiger was initially available in a [[PowerPC]] edition, with an [[Intel]] edition released beginning at Mac OS X 10.4.4 Tiger. There is no universal version of the client operating system, although Mac OS X 10.4 Tiger Server was made available on a universal DVD from version Mac OS X 10.4.7 Tiger. While Apple shipped the PowerPC edition bundled with PowerPC-based Macs and also sold it as a separate retail box, the only way to obtain the Intel version was to buy an Intel-based Mac bundled with it. However, it was possible to buy the 'restore' DVDs containing the Intel version through unofficial channels such as [[eBay]], and officially through Apple if one could provide proof of purchase of the appropriate Intel Mac. These grey-colored 'restore' DVDs supplied with new Macs, are designed to only restore on the model of Mac that they are intended for. However, they can be modified to work on any Intel Mac. The retail PowerPC-only DVD can be used on any PowerPC-based Mac supported by Mac OS X 10.4 Tiger.

The system requirements of the PowerPC edition are:<ref>{{cite web|url=http://support.apple.com/kb/HT1514|title=Mac OS X Tiger: System requirements|author=Apple|publisher=Apple|access-date=October 18, 2009|archive-date=January 5, 2010|archive-url=https://web.archive.org/web/20100105064815/http://support.apple.com/kb/HT1514|url-status=dead}}</ref>
* Macintosh computer with a PowerPC G3, G4 or G5 family processor
* Built-in [[FireWire]]
* DVD drive for installation
* 256MB of RAM
* 3GB of available hard disk space (4GB if the user installs the developer tools)

Mac OS X 10.4 Tiger removed support for older [[New World ROM]] Macs such as the original [[iMac]]s and [[iBook]]s that were supported in Mac OS X 10.3 Panther; however it is possible to install Mac OS X 10.4 Tiger on these Macs using third-party software (such as [[XPostFacto]]) that overrides the checks made at the beginning of the installation process. Likewise, machines such as [[Power Macintosh G3|beige Power Mac G3s]] and 'Wall Street' PowerBook G3s that were dropped by Mac OS X Panther can also be made to run both Mac OS X Panther and Mac OS X Tiger in this way. Also, Mac OS X 10.4 Tiger can be installed on unsupported New World ROM Macs by installing it on a supported Mac, then swapping hard drives. Old World ROM Macs require the use of XPostFacto to install Mac OS X 10.4 Tiger.

Mac OS X Tiger was the last version of Mac OS X to support the [[PowerPC 7xx|PowerPC G3 family of processors]].
