How to Fix the Critical Software Update Error

Now that we understand why this error may appear, let's explore some methods to resolve the issue and get your Mac running smoothly again.

1. Update macOS

The most straightforward way to fix this error is by installing the latest macOS update. Follow these steps to check for updates and install them:

• Press the Apple emblem located in the upper-left corner of your display.
• Choose Software Update after selecting System Settings (or System Preferences).
• Click Update Now if there is an update available.
• To finish the installation, adhere to the on-screen directions.

If the update is successful, restart your Mac to ensure all new system files are loaded.

2. Boot into Safe Mode

If your Mac is stuck on the critical software update screen and won't boot normally, Safe Mode can help. Safe Mode starts your Mac with only essential system functions, which can sometimes bypass the issue. Here's how to boot into Safe Mode:

• Turn Off your Mac.
• Switch it back on, then hit and hold the Power key right away until you see the startup disk list.
• Select the startup disk and press Shift key, then click Continue in Safe Mode.

For Intel chip Mac, just press and hold Shift key while turning on the Mac, when you see the login screen, let go of the Shift key.

In Safe Mode, try updating macOS again. If successful, restart your Mac normally to exit Safe Mode.

3. Use Recovery Mode

If Safe Mode doesn't work, try booting into Recovery Mode. This special mode allows you to repair your disk, reinstall macOS, or restore your system from a backup. To access Recovery Mode, follow these steps:

• Turn Off your Mac.
• Switch it on and hold Power button, then select Options and click Continue. (For Intel-Mac, just hit Command + R right away to see the Apple logo).

• You may use drive Utility to inspect and fix your drive or to reinstall macOS once you're in Recovery Mode.

4. Reset NVRAM and SMC

Resetting the NVRAM (non-volatile random-access memory) and the SMC (System Management Controller) can resolve hardware and software issues that may be causing the critical software update message.

How to Reset NVRAM:

• Turn off your Mac.
• To turn it on, press and hold Option, Command, P, and R simultaneously.
• When the startup chime sounds for the second time, or after around 20 seconds, release the keys.

How to Reset SMC (For Macs with Intel Chips):

• Shut down your Mac
• To unlock the Power button on MacBooks that don't have detachable batteries, press and hold Shift + Control + Option on the left side of the keyboard for ten seconds.
• Let go of all keys and restart your Mac.

If your Mac has an Apple silicon chip (M1 or later), resetting the SMC is unnecessary as it handles power management differently.

5. Reinstall macOS

If none of the above steps work, reinstalling macOS might be your only option. You can do this through Recovery Mode, as described earlier. Reinstalling macOS will overwrite the system files, fixing any corrupted ones without affecting your personal data (as long as you don't choose to erase the disk).

However, it's always a good idea to back up your files before reinstalling the operating system. You can use Time Machine or an external hard drive to back up your data.

6. Contact Apple Support

If you've tried all the solutions above and still see the critical software update message, it may be time to contact Apple Support. There could be a deeper hardware or software issue that requires professional diagnostics and repair.
