unpatchable security flaw

A new security vulnerability has been discovered in Apple's Mac and MacBook
computers – and the worst part is that it's unpatchable.

Academic researchers discovered the vulnerability, first reported by Ars
Technica, which allows hackers to gain access to secret encryption keys on
Apple computers with Apple's new Silicon M-Series chipset. This includes
the M1, M2, and M3 Apple MacBook and Mac computer models. 

Basically, this vulnerability can be found in any new Apple computer
released from late 2020 to today.
