RETURNS

I don't accept returns for a change of mind. If the Mac arrives in a condition that doesn't match the listing, you're protected by the Money Back Guarantee. The serial number is documented, so any return must be this same unit.

I'm selling it only because my setup is changing. There is absolutely nothing wrong with the Mac.

Questions are welcome—message me through and I'll get back to you quickly.
