Resetting PRAM/NVRAM on a MacBook Pro with an M-series chip, such as the M4, is not typically necessary because these models automatically manage and reset their settings during startup. However, if you suspect issues related to settings like startup disk selection, display resolution, or time zone, you can try a simple restart to see if it resolves the problem. Here's how to proceed:
1. Shut Down Your MacBook Pro: Go to the Apple menu and select "Shut Down" to power off your MacBook.
2. Restart Your MacBook: Press the power button to turn it back on. This simple restart can often resolve any issues related to settings stored in NVRAM.
3. Check and Adjust Settings: After restarting, open System Preferences (or System Settings on newer macOS versions) to ensure that your settings, such as startup disk, display resolution, and time zone, are correctly configured.
If you're using an Intel-based MacBook Pro, the process is different:
1. Shut Down Your MacBook: Go to the Apple menu and select "Shut Down" to power off your MacBook.
2. Press the Key Combination: Turn your MacBook back on and immediately press and hold the Command + Option + P + R keys. Hold these keys until you hear the startup chime twice or see the Apple logo appear and disappear twice.
3. Release the Keys: After about 20 seconds, release the keys and let your MacBook continue booting normally.
4. Adjust Settings: Once your MacBook is fully booted, check your settings in System Preferences (or System Settings) to ensure they are set as desired.
Keep in mind that M-series Macs like the M4 do not require manual NVRAM resets, as they handle these settings automatically during startup[1][2][3].
