I have a refurbished "Mid 2015" MBP that I purchased in late 2017. I entered the serial number and was shown that I'm not eligible because both: -It's not in the affected serial number range. -Our records show that your device has already been serviced as part of this Program. Was my serial number originally part of the recall, and they already knew about the issue and fixed it for refurbs going out? Is it incorrectly stating that my device is unaffected? Am I truly in the clear with this serial? To be clear, I have never taken this MBP in for service since purchase -- and it was purchased as a refurb directly from Apple.
