and AmigaShell, the AmigaDOS is the disk operating system for the OS, whereas the Shell is the integrated Command Line Interface (CLI). The CLI and the GUI complement each other and share the same privileges. Petunia, a Motorola 68020 processor emulator with dynamic recompilation, also called just-in-time compilation ( compilation), for PowerPC based Amigas. It gives OS4 backward compatibility to some extent, it will only run system friendly (following the OS3.x API without communicating directly with the classic Amigas' ) AmigaOS 3.x programs. For the programs that Petunia can't handle, such as most 'bang the hardware' (which uses legacy Amiga hardware directly) Amiga and, UAE can be used which can emulate different Amiga chipsets (OCS, ECS, AGA) as well.Īmiga OS 4.0 ran unofficially on Mac mini 1.5GHz model, but it was only a leaked version with no support for network, audio, usb etc.
If you want next generation Amiga experience on Mac hardware, then you can try MorphOS, which has similar functionality and goals with OS4, only lacking the official name, but in many parts it's better made. AmigaOS 4 version history AmigaOS 4.0 GUI: Workbench 4.0 A new.
