@Harrison; I don't think MorphOS and Amiga OS 4 are compatible in any way. However you can hack Amiga OS 4 into working on a Mac Mini so you can try running the actual OS and its software.
I've had a look around today and I found out that there is an application called OS4Emu available for MorphOS. OS4Emu is available for download at MorphOS Files.

Here's a quick description:

AmigaOS 4 emulator by Ilkka Lehtoranta. It wraps AmigaOS API calls around MorphOS calls. Supports many OS 4 specific libraries, and allows for running many applications with full speed.
