Editing System 7 (section)

===Transition to PowerPC===
System 7.1.2 is the first version of the Macintosh System Software to support Apple's new [[PowerPC]]-based computers. 68k applications that had not yet been updated to run natively on these systems were [[Emulator|emulated]] transparently (without the user having to intervene) by a built-in [[Mac 68k emulator|68k processor emulator]]. [[Fat binary|Fat binaries]], which contained the code necessary to run natively on both PowerPC and 68k systems, became common during this time. This process was similar to the distribution of [[Universal binary|universal binaries]] during the [[Mac transition to Intel processors]] in 2006, as well as the [[Mac transition to Apple silicon]] beginning in 2020.

System 7.1.2 is the only release of the Macintosh operating system that boots stating "Welcome to Power Macintosh." Release 7.1.2P reverts this.<ref>{{Cite web |date=March 14, 1994 |title=InfoWorld |url=https://books.google.com/books?id=BjsEAAAAMBAJ&dq=%22welcome+to+power+macintosh%22&pg=PA98 |url-status=live |archive-url=https://web.archive.org/web/20220915131107/https://books.google.com/books?id=BjsEAAAAMBAJ&dq=%22welcome+to+power+macintosh%22&pg=PA98 |archive-date=September 15, 2022 |access-date=January 26, 2022}}</ref>
