Since I don’t have a real Mac now, I started setting up one in Virtualbox. Its quite easy if you follow this Tutorial:
creating a mac osx vm on a windows 7
Nothing to add, except: Use at least 1024MB of RAM or it won’t install and chosse the AC97 soundcard!
It runs fine on my Thinkpad T60p with 2GB RAM and Windows 7, but giving it 50% of my RAM is really critical…
EDIT: Uhm… it runs quite slow, so I decided to install it directly on my Thinkpad. Was much faster, but had no time to fully test it
