macOS Monterey

Earlier this week, reports began pouring in that updating to macOS Monterey was bricking several older MacBooks and preventing them from turning on. Now, Apple claims it has found the issue at the root to be with the T2 security chip. It is also rolling out to fix to prevent more devices from getting bricked when they update to macOS Monterey in the future.

In a statement to Rene Ritchie seen below, Apple acknowledged the issue that allegedly affected “a very small number of users.”

Apple explained that to prevent the problem from recurring for other users, it has rolled out an updated version of bridgeOS firmware that runs on the T2 security chip in Intel-powered Macs. However, the new firmware released today will not solve the problem for users who already bricked their Macs. Apple advised users already impacted to contact Apple Support for assistance. Additionally, it said that the new T2 firmware is now included in the existing macOS updates.

Here’s a list of all the Macs that have a T2 chip on board:

  • iMac (Retina 5K, 27-inch, 2020)
  • iMac Pro
  • Mac Pro (2019)
  • Mac Pro (Rack, 2019)
  • Mac mini (2018)
  • MacBook Air (Retina, 13-inch, 2020)
  • MacBook Air (Retina, 13-inch, 2019)
  • MacBook Air (Retina, 13-inch, 2018)
