How to Fix the "Personalized Software Update Failed" Issue

When you see the error message "Personalized software update failed. Please try again." while updating your macOS, don't panic! It's quite common to encounter issues with operating system updates these days. To resolve this error, try these six top troubleshooting methods.

1. Solution 1: Check Mac Internet Connection
2. Solution 2: Retry macOS Update in Safe Mode
3. Solution 3: Clean Up Junk Files on Mac
4. Solution 4: Reset NVRAM/PRAM
5. Solution 5: Upgrade Mac's RAM
6. Solution 6: Reinstall macOS in Recovery Mode

Fix 1: Check your Mac's network connection

In order to upgrade to macOS Sonoma or any other version, a MacBook must go through a verification process with Apple's servers. This involves the server checking the measurements provided by the Mac requesting the update against the versions that are allowed to be installed. When it finds a matching version, the server adds the Mac's unique ECID to the measurements and signs the result.

As the process is tailored with ECID, you need a stable internet connection to upgrade a Mac with an Apple T2 or Silicon chip. However, if the update process gets interrupted due to unstable connectivity, you might encounter this error on different versions of macOS.

Please follow these steps to troubleshoot this error:

First, use a separate Wi-Fi network – for example, update your macOS at home rather than at work.

Step 2. If you previously set a custom DNS on your router, reset it to default.

Check the internet connection.

Method 2: Try the macOS Update Again in Safe Mode

By starting up in Safe Mode, only essential extensions load, the disk is checked, and some system issues are resolved. The steps to restart your macOS update in Safe Mode are different for Apple silicon Macs and Intel-based Macs. Here's how to start an Apple silicon Mac in Safe Mode:

Step 1: Choose Apple menu > Shut Down.

<Step 2> Hold the power button until you see “Loading startup options” on your MacBook.

Step three: Choose the volume.

Step four: Hold the Shift key and click “Continue” under “Safe Mode.”

The steps to start your Intel-based Mac in Safe Mode are as follows:

Step 1: Turn on or restart your MacBook.

Step 2: Hold down the “Shift” key until the login screen appears.

Step 3: You may need to log in again.

Your MacBook will automatically restart. When it's done, you'll see "Safe Boot" in the menu bar. You can now use "Software Update" again to update your Mac.

Fix 5: Upgrade your Mac's memory

Insufficient RAM is another reason this error might occur on Ventura or Monterey. If you suspect faulty RAM, you can run Apple Diagnostics to check or use a free software called Rember, which is licensed under GNU GPL. If you find that your RAM is insufficient, you have the option to replace or upgrade it. Here are the steps to upgrade your memory:

Step 1: Power down your Mac and let it cool completely. Now's the time to unplug all cables, cords, and peripherals.

Step 2: Stand the laptop on its end with the screen facing down.

Step 3: Remove the bottom case

Step 4: Discharge any static electricity stored in your body by touching a metal surface on the MacBook.

Step 5: Search for the “RAM module” and remove it using the lever that pops up.

Step 6: Don't touch the gold contacts; just lift the RAM module straight up and out.

If you have additional memory modules, repeat this step.

Step 8: Carefully install the new “RAM modules” into your MacBook, without touching the gold contacts.

Step 9: Snap in the second module until it clicks into place.

Step ten: Install the bottom cover and tighten the screws.

If your RAM is the issue, perform the above steps, and don't forget to share with your friends on social media.

Solution 6: Reinstall macOS in Recovery Mode

In this solution, you need to know the ideal combination for survival. Before starting, make sure you have a strong and stable internet connection. Follow these steps:

Step 1: Turn on your MacBook.

Step 2: It's now time to press the “Command + R” keys, which will boot your device into the latest version of macOS that's installed on it.

Then press “Option+Command+R,” and that will install the latest version of macOS that's compatible with your Mac.
