Weekly News Summary for Admins — 2021-01-15

The year is just starting, but Apple is waking up nearly as fast as an M1 MacBook Air. We got new betas for macOS 11.2 and iOS 14.4. MacAdmins have been busy, too. Thank you for all the great articles!

  • Hector Martin: “So I’m working in understanding the Apple Silicon boot/OS provisioning process. This is all subject to change, but here are some takeaways according to my current understanding.” (Thread)
  • Joel Rennich: “While it still needs work, specifically around how Apple gates token access, this is PKINIT on an iPhone using the Single Sign On Extension and a CryptoToken Kit extension at the same time.” (Movie, thread)
  • Patrick Wardle: “The ContentFilterExclusionList list has been removed (in macOS 11.2 beta 2)!! This means socket filter firewalls (such as LuLu) can now comprehensively monitor & block all network traffic)”
