Apple computer can run on 220V from 110V power supply?

No, of course not. The power supply needs to match the 'wall power' to provide the proper voltages to the motherboard. On the bright side, most power supplies sold in the US have a slide switch to select between 110/220 volts input. It may be as simple as moving a little red switch on the back of the power supply to configure your power supply to 110 v.
