MAC question How to change
 

I took over an Imac from an other person and his name is located as the administrator and when I have to install a DMG packet the system is popping up his name.

In fact the name of the Mac.

I want to change that also the name that is shown at the harddisk menu.

The admin name I think you can do it here: System Pref > Accounts then change the name there.

And try right clicking on the HD in the menu, select GET INFO, then choose name and it lets you edit it there I believe.

Thanks mate I will try it out!
