I'll most likely attempt to sell my old iMac on Craigslist for a minor profit to help pay for my new computer. I'm used to selling things on Craigslist and meeting them in a public place to do the exchange. But for an iMac, I'm assuming the buyer would want to see that the computer is working properly and powers up appropriately. I'm uncomfortable letting some strangers into my home to check out a computer. Any advice to get around this?
