MacBook Air turns on automatically when lid is opened

The new M1 MacBook Airs are designed to turn on when opening the lid and can't be defeated, just as pressing any key will start it up if left open.

There are actually several mechanisms for a Mac to start up on its own.

• For Intel-based Macs without the T2 Security Chip, the System Management Controller (SMC) is responsible for powering the system on automatically.

• For Intel-based Macs with the T2 Security Chip, the SMC is integrated directly into the T2 Security Chip. It is responsible for powering the system on automatically.

• For Macs with Apple silicon, the SoC includes an Always On Processor that continues to run even when the rest of the system is shut down. It is responsible for powering the system on automatically.

The most well-known examples of automatic power-on are listed below:

• Setting a power schedule in System Preferences and requesting Power-on/Wake at a certain day or time.

• Opening the lid, or pressing the keys or trackpad of Mac notebooks (autoboot). There might be an NVRAM variable to disable this behaviour.

When you shut down the Mac it will auto start when the lid is opened on the new M1 units.

How can you assume that it is a M1 MacBook?
