The one serious MacBook Pro security flaw that nobody is talking about:

It’s the USB-C ports. Because of the USB-C ports, all MacBook Pros introduced since late 2016 are inherently unsafe. Likewise, all of the 12-inch MacBooks introduced since 2015 are inherently unsafe.

Yep. The article cites several cogent references supporting the premise.
It’s funny how hardware manufacturers, including Apple, moved power to a shared data port like USB-C where I expect users cared more about disposing of the myriad proprietary power connectors. Apple, with MagSafe, designed and delivered an elegant solution. More and more vendors eschew ports in the vain pursuit of thin, and this puts customers (you and me) potentially at risk.

Be nice with what you write.
