Fractal Music sort of worked under Lion in another emulator called Hatari, but that failed in later versions of Lion and to the best of my knowledge that hasn’t changed since. It was even working in the NoSTalgia Atari ST emulator under Mac OS X up to version 10.6 (Snow Leopard), but unfortunately, NoSTalgia is a PowerPC application and stopped running when Mac OS X became Intel only. Quaint though it may seem now in many ways, Fractal Music does still work, and produces results that are still, as far as I know, unique… but only if you still have an Atari ST though (see 2021 update below) or are running an old version of whatever OS you use. For the time being, what follows may be helpful to users with older operating systems. I will however be doing some more research into this and will update this page accordingly.
My current Mac runs macOS 10.15 (Catalina) and as far as I can tell, sadly, I can no longer run Fractal Music at all. Please note that the compatibility notes that follow are now out of date. Fractal Music’s main screen on first loading
