Hello William,
Dropshipping for Macbooks, or other electronics such as laptops has not really been recommended.For droshipping, you actually do not need to pay out of your own pocket, you wait until you make that sale and the actual purchase amount paid can be used to pay for the item. You might be thinking, big savings right?
Remember, though, that the prices that the suppliers will provide you will be a lot closer to actual retail. Therefore, the margin for your profit will be a bit tight. Unless you have a big market for these babies, then go ahead.
In line with this, it would always be best to contact the suppliers or liquidators regarding Macbooks because as far as I know, these brands are usually sold via their official sites or the liquidators.
Hope this helps.
