The last Apple operating system that can run on the PowerPC architecture, Mac OS X Leopard (10.5, October 2007), can not run on PearPC due to the lack of system requirements. With the integrated JIT compiler, which is still experimental with version 0.5.0 (July 2011), the emulated PowerPC guest operating system reaches around 10 percent of the speed of the host system and is therefore sufficiently fast on modern hardware.
OpenBSD and NetBSD, for example, crash when booting because the emulation was not optimized for it. Accordingly, only Mac OS X version 10.1 “Puma” (September 2001) up to version 10.4 “Tiger” (April 2005) runs approximately stably under the emulated hardware.

Darwin and Linux, the goal is unmistakably to create an emulation environment for Mac OS X. Īlthough other PowerPC operating systems run on PearPC, including a. PearPC is not suitable for productive use. CherryOS disappeared from the market at the end of 2005. Since the GPL requires disclosure of the source text, there was a clear license violation by its developer Arben Kryeziu, who did not comply with this license agreement. On x86 processors, the execution speed can be increased by a factor of approximately 15 using the JIT compiler.īetween 20 there was a commercial PowerPC emulator called CherryOS, but it turned out to be a fork of PearPC with an integrated HFV Explorer. The emulated computer can share an internet connection of the host computer ( bridging ).Ī platform-independent interpreter allows the PowerPC instruction set to be implemented on any architecture, but is very slow at a factor of approx. Compatible operating systems are the PowerPC variants of Mac OS X, Darwin and various Linux versions. PearPC either emulates a PowerPC G3 - or -G4 processor, an IDE - interface, mouse and keyboard, network cards and one PCI - Graphics card. Version 0.5.0 was not released until 2011, which creates improved compatibility with the 64-bit platform 圆4, since the x86 JIT compiler can now also be used with the 64-bit instruction set extension AMD64 and Intel 64. Version 0.4.0 from December 2005 upgraded AltiVec emulation. Most of the development took place in 2004 with the PearPC versions 0.1-0.3.1.
