NVRAM Reset
Hello All...
I've been struggling with the inability to reset the NVRAM on my MacPro (Desktop; tower). Does anyone know an alternate to the standard Command/Option/P/R keys at startup method? (When I attempt this, the computer starts as though I've done nothing...single chime>login screen...apparently not recognizing the keys being held down) I've read that if Apple's firmware protection has been enabled, then the this can be one of the results (not recognizing these key presses). However, I have never enabled firmware protection, nor do I know where I might look to see if somehow it's been erroneously enabled.Does anyone know anything further about this?
That being said, the reason I'm wanting to reset the NVRAM is I'm experiencing several mysterious behaviors as of recent...
1. My magic mouse has been acting erratically, lagging and skipping, rendering it virtually useless.
2. I can no longer access my CD/DVD drives. They show in Disk Utility, but are grayed out, and indicates the drive is busy (I have 2, and the same for both)
3. When the computer has been asleep for longer periods (12 hr+), it won't wake by pressing a key on the keyboard, nor the mouse, I need to press the power button. (This never was the case previously)
Not sure what to do from here, if anyone has a solution to this vexing problem, I'm all ears.
Thanks,
