2. **Restart your Mac.** Sometimes, a simple restart can fix problems with keyboard shortcuts.
3. **Check for updates.** Make sure that your Mac is up to date with the latest software. You can check for updates by going to **System Preferences** - **Software Update**.
4. **Reset the NVRAM.** The NVRAM (non-volatile random-access memory) stores certain settings for your Mac, such as the startup disk, time zone, and speaker volume. You can reset the NVRAM by following these steps:
* Restart your Mac.
* Immediately after hearing the startup sound, press and hold the `Command` `Option` `P` `R` keys.
* Keep holding the keys until you hear the startup sound again.
* Release the keys and let your Mac start up normally.
5. **Check for malware.** Malware can sometimes interfere with the keyboard shortcuts. You can scan your Mac for malware using an antivirus program.
6. **Contact Apple Support.** If you have tried all of the above steps and the screenshot shortcuts are still not working, you can contact Apple Support for help.
iii. The NVRAM (non-volatile random-access memory) stores certain settings for your Mac, such as:
Startup disk selection;
Time zone;
Audio volume;
Screen resolution;
Startup disk checksum;
Recent kernel panic information.
iv. The Recent kernel panic information is stored in the NVRAM, which is a small amount of memory that is used to store certain settings for your Mac. If the NVRAM is corrupted or contains incorrect information, it can cause problems with your Mac, including preventing the screenshot shortcuts from working.
To fix this problem, you can reset the NVRAM by following the steps above. This will clear the NVRAM and restore it to its default settings. Once the NVRAM has been reset, the screenshot shortcuts should start working again.
If the screenshot shortcuts are still not working after you have reset the NVRAM, you may need to contact Apple Support for help.
v. Here are some things you can do if your Mac NVRAM is not resetting:
1. **Make sure you are pressing the correct keys.** The keys you need to press to reset the NVRAM are `Command` `Option` `P` `R`. Make sure you are pressing all four keys at the same time and holding them down until you hear the startup sound for the second time.
2. **Try resetting the NVRAM while your Mac is in Safe Mode.** To do this, restart your Mac and hold down the `Shift` key until you see the Apple logo appear. Once you see the Apple logo, release the `Shift` key. Once your Mac has booted into Safe Mode, follow the steps above to reset the NVRAM.
3. **If the NVRAM is still not resetting, you may need to take your Mac to an Apple Store or an authorized Apple service provider for further assistance.**
Here are some other potential causes of your Mac NVRAM not resetting:
* **Your Mac's battery is low.** If your Mac's battery is low, it may not have enough power to reset the NVRAM. Try charging your Mac for at least 30 minutes and then try resetting the NVRAM again.
* **Your Mac's hard drive is failing.** If your Mac's hard drive is failing, it may not be able to store the new NVRAM settings. Try replacing your Mac's hard drive and then try resetting the NVRAM again.
* **Your Mac has a hardware problem.** If your Mac has a hardware problem, it may not be possible to reset the NVRAM. In this case, you will need to take your Mac to an Apple Store or an authorized Apple service provider for further assistance.
