Should you try changing NVRAM settings in an Apple silicon Mac? As they’re almost certain to have no beneficial effect, and could require lengthy procedures to reset them, it’s best not to try.
Still very useful procedures for Intel Macs, resetting the SMC within a T2 chip is more complex. Used wisely they can resuscitate a failing Mac.
Fed up with your M1 MBP always starting up, or waking from sleep, when you open its lid? How might you change that behaviour?
How to discover what’s stored in your Mac’s NVRAM, how to reset it in Intel Macs, and how you can changes its variables.
