Im trying to determine whether the full os is available when the 27" is running in target display mode. The fact that the imac needs to be booted to do this, would indicate that is the case, but when I asked the question in a store I was told that it was not. to be more specific, If I have apps running on the imac and enter 'target display mode' do these apps continue to run? can I remote desktop into my imac when in 'target display mode'? can I run vmware with server software in the imac when in 'target display mode'? Logic would seem to say 'yes, of course'..but I can't find any definitive information either way. Can someone with a 27" and a modicum of technical skill, please advise.
