Installed fairly easily. Followed the dual boot guide and all is working well (including sound).
Initially, OSX complained that the "Boot" partition needed repair -- I ended up reformatting that partition with OSX and then reinstalling MorphOS. Then I edited /etc/fstab/ so that the "Boot" partition wouldn't be mounted when OSX booted.
I also edited OF to "skip-netboot" (as noted in the guide), which made a big difference on my machine.
Oh, yeah -- registered too!
Edit: Holy cow! Already received the keyfile!
