There is a big possibility the author just bought a counterfeit, AFAIK all consumer electronic devices have standard EMC compliance requirements, these spikes showed should be easily observed in the 10M chambers during testing.

The device was ordered from Apple's website.

The issue could be coming from the AC-DC charger used with the MagSafe charger as well, maybe retest with an Apple charger?

The issue was confirmed with two separate MagSafe chargers and three or four separate AC/DC chargers. The lab test in the post was done using laboratory DC power supply powering a DC to USB converter.

Also if the interference didn't come from the disc side of charger then the issue wouldn't be resolved with ferrite bead on that end. If the issue was on the USB connector side then the bead should be placed there.
