Hey there, and welcome to Apple Support Communities miramass,

We can certainly understand your concern and are here to help.

We recommend checking out these steps for more information on performing an NVRAM reset to see if that helps the issue.

" Reset NVRAM on your Mac

If one or more settings stored in NVRAM aren't working as expected on an Intel-based Mac, resetting NVRAM may help.

Do you need to reset NVRAM?

NVRAM (or PRAM) is a small amount of memory that your Mac uses to store and quickly access certain system settings, such as sound volume, display resolution, startup-disk selection and time zone. These settings vary by Mac and the devices you're using with it.

Normally you can manage these settings in System Preferences, without resetting NVRAM. If one or more settings still aren't working as expected, resetting NVRAM may help. Resetting NVRAM is also the recommended final step before you sell, give away or trade in an Intel-based Mac.

If you're not using a Mac with Apple silicon, you're using an Intel-based Mac.

How to reset NVRAM

1. Shut down your Mac.
2. Turn on your Mac, then press and hold these four keys together immediately: Option, Command, P, R.
3. Release the keys after about 20 seconds, during which your Mac may appear to restart. For example, you may hear a startup sound more than once, or see the Apple logo more than once.
4. When your Mac has finished starting up, you may need to adjust any system settings that have been reset."
