In any case, I thought I take you through a few screenshots of installing VMware Tools for a Mac OS X 10.7 guests running on my Apple Mac Mini.
It is still amazing to me to see the number of guest OSes the vSphere platform supports and perhaps virtualizing Mac OS X is still relatively new for folks and hence the initial assumption about VMware Tools not being available. I guess it may not be that well known or just an assumption, but VMware Tools does in fact exists for Mac OS X guests and it is also documented in the VMware Tools installation guide. A comment that came up yesterday on Twitter was that VMware Tools did not exists for Mac OS X guests and this would make it difficult to manage Mac OS X guests on vSphere.
To do so, you would need to be run ESXi on Apple hardware either the now deprecated Apple XServe 3.1 or an Apple Mac Pro. With the release of vSphere 5, virtualizing Apple Mac OS X as a guest OS was possible and fully supported from VMware.
