Security researcher Niels Hofmans of ironPeak has confirmed a T2 chip security flaw. These chips have been found in all new Macs made since 2018.

The 50-minute talk, titled “Behind the scene of iOS and Mac Security,” will take place on August 8. Krstic describes it as the “first public discussion of several key technologies new to iOS 13 and the Mac.”
