kernel panic after macos Sierra upgrade
Upgraded a MacBook Air to Sierra yesterday. System boots up to the login prompt but during the login process it just hangs. Pressing a key results in a kernel panic.
The normal/old way of invoking safe mode didn't work, so I booted into recovery terminal and issued nvram boot="-x" to get to safe mode. The system boots and reports polling smartbattery for a while until you press a key and it kernel panics again, unfortunately the panic message is displayed so quickly I can't actually see what the issue is.
Any ideas?
