I have my old pentium system. I tried to use Snow Leoprad (10.6) and got warning that system do not support it. So I downloaded a bit earlier version of MAc os 10.4 and 10.5 that should be without its requirements. Is it really so? Can I use such dmg (or after conversion to ISO) images in VirtualBox on Windows Xp host? Can I use settings to overlook absence of vt-x of my proc? The second issue is can I use os x server 5 as OS for Xcode (ios) in Vbox to not use MAc os 10 desktop? As I read that virtual box just use server not desktop images. And my Vbox 3.2 have just options for MAc OS and has not version option for MAc os server -- is it mean it is obsolete? Should I upgrade? And I converted small 180 mb os x server dmg image to iso (by anytoiso app) as I have error on dmg -- but when launching virtualbox machine i got -- not bootable medium. System halted- should it mean bad conversion by anytoiso? How do it correctly if possible?
