Add New Symbol to MetaTrader and Import Data?

With MetaTrader can I create a new symbol and import data into it from my PC, and select the new symbol with File/New Chart?

If this is possible can I do this while MetaTrader is online with my broker?

Is anyone here using Metatrader in Mac computer.
I know that Metatrader doesn't work in Mac.
If anyone here know any alternative to use the system with Mac.. let me know.

Thank you.

You didn't say if you have an Intel mac or PPC. If you have a newer Intel Mac then its runs great in Parallels virtual workstation which essentially runs XP or Vista at the same time as Mac OS. It costs about $50.

If you have an older PPC mac then don't think you have an option.
