I Cant access Security pane in system preferences? I had an old 07 (intel) imac running leopard, I then bought a new imac last december, did a full time machine back up first. I then fired up the new imac restored from time machine, then installed snow leopard, all fine and dandy apart from one thing 'I Cant access Security pane in system preferences?' I have repaired permissions, deleted the plist thing, created a new user which also couldn't access the security system pref. My last hope was the re install snow leopard which I did with no luck. I can only think that I need to re install snow leopard in a particular way as I ended up having to restore from time machine once again which probably put the gremlin back in the system. I am hoping 'OS Lion' will be the answer but I don't wont to wait any longer... its pis*ing me off big time. ANY ideas would be greatly appreciated.... this is my first post.
