For an iMac equipped with an Intel processor, the non-volatile RAM, commonly known as NVRAM, holds critical settings necessary for the computer's functioning before accessing the hard drive or initiating the operating system.
In case these settings encounter corruption, a reset procedure during the iMac's startup allows you to restore them to their default state.
However, if you find yourself in a situation where the NVRAM reset isn't working, worry not. This guide will walk you through three practical steps to rectify this problem and get your Mac back in top-notch condition:
- Step 1. Restart Your Mac
- Step 2. Check the Update on Your Mac
- Step 3. Try to Reset NVRAM Again on Your Mac
NVRAM Reset Not Happening, Why
Resetting NVRAM on a Mac is a crucial troubleshooting step to fix various system-related issues. NVRAM (Non-Volatile Random-Access Memory) stores critical settings like volume, display resolution, and startup disk selection, which resetting can often resolve.
However, if the NVRAM reset not working, it could be due to several factors. One common reason could be setting a firmware password, preventing the reset process.
Plus, software glitches or hardware malfunctions may obstruct the normal NVRAM reset, causing the Mac to boot up regularly without the reset happening as intended.
In Advance: Back Up Your Data Before Resetting NVRAM
Before undertaking any major system modifications like resetting NVRAM on your Mac, it's crucial to ensure your valuable data is safeguarded. Data loss can occur due to various unexpected circumstances during such processes. Therefore, it's highly recommended to create a comprehensive backup of your important files and documents.
Back Up Your Mac and Never Lose Data
Back up and restore your MacBook/iMac without Time Machine, iCloud, or external hard drives.
Data loss can happen, whether due to a technical glitch, accidental deletion, or system modifications like NVRAM resets.
In these unforeseen situations, having a reliable data recovery solution is paramount. EaseUS Data Recovery Wizard for Mac Pro stands as a reliable tool, ensuring your data remains retrievable. It is designed to recover permanently deleted files on Mac, including documents, photos, videos, audio, emails, and more. Whatever you've lost, this tool can likely retrieve it.
Check out the following steps to back up your data in case you lose it:
Step 1. Click "Disk Backup" > "Create Backup" > "Next" in EaseUS Data Recovery Wizard for Mac's main interface. You can create a drive backup image file in case the data is overwritten.
Step 2. Select an internal volume to back up, and click "Create Backup". If you want to create backups and recover data from an external hard drive, USB flash drive, or SD card, remember to connect the storage device to your Mac in advance.
Step 3. Choose a place to save your backup files, and change the name of your backup file, then click "Save". It is not wise to save backups in the same storage device that you want to recover data from.
