Recently, while setting up my office at Colby, I realized my old iMac wasn’t working anymore. The issue was simple: I just had to reset the NVRAM. Here’s how you can do it too:

How to Reset NVRAM:

1. Shut down your Mac completely.
2. Turn it back on, and immediately press and hold Option + Command + P + R.
3. Hold the keys until you hear the startup sound or see the Apple logo twice, then release.

This reset can resolve issues like display resolution, sound, or system preferences.

Just in case you need to Reset the SMC (for Intel Macs):

If your Mac isn’t turning on, or you’re experiencing issues with battery, fans, or keyboard backlighting, try resetting the System Management Controller (SMC):

1. Shut down your Mac.
2. On the keyboard, press and hold the left Shift, Control, Option keys, along with the power button, for 10 seconds.
3. Release all keys, then press the power button again to turn on your Mac.

This should resolve hardware-related issues and get your Mac back to normal!
