Some updates could not be installed message

Hi annioneil,

Thanks for contacting Apple Support Communities!

We understand that you're seeing an alert that some updates couldn't be processed while updating macOS.

There are a few steps you can take to help isolate this behavior such as installing macOS via safe mode, macOS Recovery or running First Aid to repair the disk. This article will guide you through the complete process: If an error occurred while updating or installing macOS - Apple Support

"Install after repairing your disk

Use Disk Utility to repair your startup disk. Then try updating or installing macOS again.

Install from macOS Recovery

Install while your Mac is started up from macOS Recovery. This gives you the latest version of the macOS currently or most recently installed. To start up from macOS Recovery, follow the appropriate steps:

Apple silicon

Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Intel processor

Turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password. When you see the utilities window in macOS Recovery, select Reinstall macOS, then click Continue and follow the onscreen instructions. Learn more about using macOS Recovery to reinstall."

We hope this helps you.

Cheers!
