Dears, this is my first post so first, hello to all of you. I'm trying to install a OSX 10.6 in a virtualbox on a 10.6 iMac. In fact, I'm just trying to use the provide DVD of my own iMac to create a new instance in the Virtualbox (to have a "scratchable" OS for some testing and tries purpose) When I install the OS in the Virtualbox, I get a "cannot install OS in this machine" ! Which at first glance sounded strange to me. After reading the web, I understood Apple restrict the installation of an OS on a different machine (or at least configuration). I guess the Virtualmachine is not recognize as a "similar" one compared to my physical one. Does anyone has a clue on the virtualbox settings to use to make it work ? What are the settings the OS is linked to that prevent my virtual machine to install correctly ? I noticed I cannot have more than about 3.5Gb or ram in the virtual machine but my physical one has 4Gb. Perhaps this difference prevents the OS to install. Any idea or solution welcome. Kind regards.
