* Data protection silently bypassed
* No user-visible indication of degraded security posture
## Proof of Concept
Captured logs from affected hardware confirm SPU and digitizer failure, as well as fallback behavior in key services:
```
aoprose: PRRose::setStateFromUnknownToHost: FWState::SecureROM
AppleSPU::_handleReadyReport, serviceName (arc-eeprom-i2c)
Couldn't alloc class "AppleSPULogDriver"
Couldn't alloc class "AppleSPUGestureDriver"
RawI2C slave presence test: 6265
_enableControlI2C currentControlReg = 0x60
IOHIDEventDriver: Invalid digitizer transducer
AppleSphinxProxHIDEventDriver: Invalid digitizer transducer
```
Additional system logs reveal cryptographic fallback and loss of encryption enforcement:
