PearPC is an architecture-independent PowerPC platform emulator capable of running many PowerPC operating systems, including Mac OS X, Darwin and Linux. It is released under the GPL. It can be executed on Microsoft Windows, Linux, FreeBSD and other systems based on POSIX-X11. The first official release was made on May 10, 2004.

The emulator features a Just-in-time (JIT) processor emulation core which dynamically translates PPC code into x86 code, caching the results. Despite running only on x86 host architectures, the JIT emulation core runs at least 10 times as fast as the architecture-independent generic processor emulation core, and is the key to achieving usable real-time emulation. For other uses, see Just In Time. ...

PearPC seems no longer in development although until December 2005 it advanced quickly in speed, stability and features. It is hoped to achieve the goal of 1/10 host speed relatively soon. Individuals are making builds with more features like native CD-ROM support and even progress in emulating sound has begun. Popular PearPC sites that provide builds also include Altivec support for PowerPC G4 processors. Support for graphics cards acceleration is in progress, which in theory should provide a major performance boost due to OS X's hardware-accelerated GUI known as Quartz-Extreme. AltiVec is a floating point and integer SIMD instruction set designed and owned by Apple Computer, IBM and Motorola (the AIM alliance), and implemented on versions of the PowerPC including Motorolas G4 and IBMs G5 processors. ...

Shortcomings
The current version of PearPC is 0.4.0 (released December 20, 2005). While its PowerPC emulation handles most applications and the emulator already has an impressive feature set, the project still lacks features needed for a complete emulation of the PowerPC experience: - Sound emulation
- G5 emulation
- .dmg support for use as an image (currently, to use a .dmg image the file must be converted into an .iso image)
On June 6th, 2005, Apple's CEO, Steve Jobs, announced that Apple will begin switching their computers' architectures from IBM's PowerPC to Intel's x86 platform. The transition was completed in August of 2006. The news raised a lot of questions about the future of the PearPC project, because although the project itself is a PowerPC emulator, it is used primarily to run Mac OS X on x86 machines. If Mac OS X will run natively on the x86 platform, PearPC's emulation may possibly be replaced by VMware Fusion or other virtualization products.

Frontends PearPC currently lacks its own GUI — the 'Change CD' button found in early versions has been eliminated because it rarely functioned correctly. However, developers have made frontends for the program. Two of these are PearGUI, which looks like a Mac OS X application but is incompatible with current versions of PearPC, and PearPCCP (short for "PearPC Control Panel"), which is compatible with PearPC 0.3 and newer. PearGUI's incompleteness annoys many users and its 'Create Disk Image' feature is not yet complete (a severe shortcoming), but many users have praised its GUI. PearPCCP has a built-in configuration wizard in addition to other advanced features, but is hindered by what many users believe to be an inferior interface and several bugs. Some users also report that PearPCCP removes comments from configuration files, while PearGUI does not. The PearPC.net website also released its own Java-based PearPC-GUI, called APE, which is part of the PearPC.net Package. CherryOS is alleged to be simply a front end for PearPC. Its website was shut down in May 2005. GUI can refer to the following: GUI is short for graphical user interface, a term used to describe a type of interface in computing. ...

CherryOS controversy Within five months of PearPC's release, another PowerPC emulator called CherryOS appeared, claiming to offer more features and greater speed. However, within hours of its announcement, questions were raised about the claims, with many experts and open-source advocates suggesting that CherryOS was nothing more than a repackaging of PearPC. The CherryOS Emulator was re-released in March 2005 as a commercial product. According to many experts, it still contained all or part of the code written for the PearPC Project. CherryOS also created questions regarding the legality of commercial software developed and marketed specifically for the purpose of running Mac OS on the x86 architecture, since Apple's license agreement specifically states that the operating system may only be installed on Apple-labeled computers. Eventually, the distribution of CherryOS ceased due to the very high amount of criticism that had been directed at it.
