HistoryEdit

PearPC was released in May of 2004 by developers Sebastian Biallas and Stefan Weyergraf.<ref name=":2">Template:Cite magazine</ref> Original releases were noted for being slow and unstable,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> but were still well received by the community.<ref name=":3">Template:Cite magazine</ref> On July 6, 2004, Weyergraf was killed by a train, but development continued.<ref>Template:Cite magazine</ref> The last current version of PearPC was 0.5.0, released on July 12, 2015. One of the reasons given for the development slowing down after 2005 was Apple's transition from PowerPC to x86 architecture.

FeaturesEdit

PearPC only runs on x86 systems including Intel and AMD such as Windows, Linux, FreeBSD, and ReactOS.<ref>Template:Cite magazine</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The emulator features a just-in-time (JIT) processor emulation core which dynamically translates PPC code into x86 code, caching the results. The original release emulated a G3 chip.<ref name=":2" /> The emulator shipped with the ability to run Mac OS X 10.3, OpenBSD for PowerPC, NetBSD for PowerPC, Darwin for PowerPC and Mandrake Linux 9.1, though it was noted that the emulated operating systems could be up to 40 times slower than the host.<ref name=":0" /> This speed was later brought up, running around 10 times slower than the host.<ref>Template:Cite book</ref> It could run all the regular Mac applications such as Finder, Safari, QuickTime, and Terminal.<ref name=":3" /> The emulator can run Mac OS X versions 10.1 through 10.4 but cannot run 10.5 Leopard or above. Support for the G4 chip was later added.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

ShortcomingsEdit

The current official version of Pear PC is 0.5.0 (released on July 12, 2015). While its PowerPC emulation handles most applications, the project still lacks several components needed for a complete emulation of the PowerPC experience. Sound emulation, G5 chip emulation, .dmg support, and OS X Leopard support were not included in this release. The installation was sometimes noted as complicated,<ref>Template:Cite book</ref> requiring editing of configuration files and the use of the command line.<ref name=":1" /><ref>Template:Cite book</ref>

CherryOS controversyEdit

Template:Further A commercial PowerPC emulator called CherryOS was released soon after the launch of PearPC, in March 2005, claiming to offer more features and greater speed. However, within hours of its announcement, questions were raised about the claims, with some people suggesting that Cherry OS was nothing more than a repackaging of PearPC. According to Cassondra Foesch, a principal author of PearPC, it still contained all or part of the code written for the PearPC Project. Cherry OS also created questions regarding the legality of commercial software developed and marketed specifically to run macOS on the x86 architecture, since Apple's license agreement specifically states that the operating system may only be installed on Apple-labeled computers.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On April 6, 2005, the distribution of Cherry OS temporarily put on hold due to criticism.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was later released as open source on May 1, 2005.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
