[[AmigaOS 4]] is designed for PowerPC Amiga systems. It is mainly based on AmigaOS 3.1 source code, with some parts of version 3.9. Currently runs on both Amigas equipped with CyberstormPPC or BlizzardPPC accelerator boards, on the Teron series based [[AmigaOne]] computers built by [[Eyetech]] under license by [[Amiga, Inc.]], on the [[Pegasos|Pegasos II]] from [[Genesi]]/[[Genesi|bPlan GmbH]], on the [[ACube Systems Srl]] [[Sam440ep]] / [[Sam460ex]] / AmigaOne 500 systems and on the A-EON [[AmigaOne X1000]].

AmigaOS 4.0 had been available only in developer pre-releases for numerous years until it was officially released in December 2006.<ref name="AutoP5-18" /> Due to the nature of some provisions of the contract between Amiga Inc. and [[Hyperion Entertainment]] (the Belgian company that is developing the OS), the commercial AmigaOS 4 had been available only to licensed buyers of AmigaOne motherboards.

AmigaOS 4.0 for Amigas equipped with PowerUP accelerator boards was released in November 2007.<ref name="AutoP5-19" /> Version 4.1 was released in August 2008 for AmigaOne systems,<ref name="AutoP5-20" /><ref name="AutoP5-21" /> and in May 2011 for Amigas equipped with PowerUP accelerator boards.<ref name="AutoP5-22" /> The most recent release of AmigaOS for all supported platforms is 4.1 update 5.<ref name="AutoP5-23" /> Starting with release 4.1 update 4 there is an Emulation drawer containing official AmigaOS 3.x ROMs (all classic Amiga models including CD32) and relative Workbench files.

[[Acube Systems]] entered an agreement with Hyperion under which it has ported AmigaOS 4 to its [[Sam440ep]] and [[Sam460ex]] line of PowerPC-based motherboards.<ref name="AutoP5-24" /> In 2009 a version for [[Pegasos II]] was released in co-operation with Acube Systems.<ref name="AutoP5-25" /> In 2012, A-EON Technology Ltd manufactured and released the [[AmigaOne X1000]] to consumers through their partner, Amiga Kit who provided end-user support, assembly and worldwide distribution of the new system.
