Unable to update macOS Sequoia 15.4.1 on my Mac mini

My Mac Mini M1 keeps telling me it wants to update OS but it doesn't update. ("macOS Sequoia 15.4.1 is available and will be installed later tonight.")

It says it'll update in the night...I leave the computer on (monitor is off so it doesn't wake me up) but the next morning it's still not updated and asked me again do I want to update tonight.

What's wrong? Does the monitor have to be on? Thanx

I have seen numerous users claim the M1 chip, be it on Desktop or Laptop, have had issues updating to Sequoia 15.4.1

Though, like all Apple Computers that are designed and built by Apple

This specific M1 Mac Mini is designed by Apple to handle Sequoia of any version including Sequoia 15.4.1

The question often overlooked is " How Much Empty Space " was on the drive before 15.4.1 was attempted to be installed

Depending on what version is currently installed and if you have enable Apple Intelligence

Apple Intelligence when enabled will use about 10.58 GB of space above and beyond the space needed for the Operating System

In some early versions of macOS - an update may have presented a Warning about Not Enough Empty Space

Then, balk during the attempted update process

What I am seeing now is the Warning Message does not always happen

Then, the user is left with " still not updated and asked me again do I want to update tonight. "

Restart the Mac mini and try updating.

Then if an error occurs while trying to update..?
