To clear NVRAM/PRAM on an Intel-based MacBook, shut down, turn it back on, and immediately hold Option + Command + P + R for about 20 seconds, or until the Mac restarts and you hear the second startup sound (or see the Apple logo appear/disappear twice). This resets settings like volume, resolution, and startup disk
