In Canada, we're guilty until proven innocent... Your friend is going to have to testify in your behalf and assure the court you had no idea the Mac was stolen. But the Crown is going to ask your friend where he got it, etc, etc... If there is any doubt at all, you're screwed.
I am being charged with possession of stolen property. I didn't know the property was stolen. What do I do? I live in Canada, Saskatchewan.
Do you have a receipt for it? Was it a car with the ignition punched out? Is there anything about the property that would cause suspicion in a reasonable person? Was there anything about the seller that would cause sispicion in a reasonable person?
