Hello !
Installation is a bit hardy, that's why it is written "Only for advanced users".
Follow the installation instructions given in the file "VirtualMachine Help.webloc" otherwise it wouldn't work !
This app is useful for me but we can can do without... So if you don't understand how to install this or have a doubt, don't hurt your head, it isn't the end of time.
I hope the dev will try to implement an easier installation process.
Another thing : I didn't find the traditional icon of VM. I think it was zapped by the compression method used by the dev, excluding .icns. Or perhaps it's my compression softs...
I think this soft is a good idea but neads to be improved. Carry on !
