Apple has released a new version of its Platform Security Guide, outlining the security and privacy innovations and improvements its users will be able to take advantage of. In late 2020, Apple unveiled the first lineup of computers with M1, a new, in-house built chip that is meant to power all of its computers in the future. The M1 chip is supposed to speed up Macs and improve their performance, but according to the updated guide, there are new security protections built deep into M1’s code execution architecture.
