I want to install macOS Monterey but it doesn't allow me as it said 'Failed to Personalise the update. Please Try again.' Can you please help me fix it as I am a developer and I need help to install Monterey on my M1 MacBook Air. Here are the actions that I did which led to this error: Downloaded and Installed the macOS Monterey Beta from the Developer Site Opened the Installer directly by double clicking it Chose Macintosh HD (Main Startup Drive) to install macOS Monterey Beta. Installer stuck at 52 Minutes remaining before speeding up to an error popup. Error Popup, the popup shows: ‘Failed to personalise the update. Please try again.’ 6. Repeated Step 2+3 Multiple times and tried again many times 7. Nothing had improved The results I expected was the installer requesting for a restart and successfully installing the Beta after the restart. The results I saw was the ‘Failed to personalise the update. Please try again.’ As shown above in the steps, I had tried this multiple times but nothing had improved and everything was not what expected.  STEPS THAT I TRIED TO FIX IT BUT WAS NOT SUCCESSFUL: Restarted the computer Restarted the installer Asked developer support for help (developer.apple.com/support) If you can solve this and get me going into installing the Operating System, that’ll be great. Thanks everyone!
