High Sierra says it is installed but "About this Mac" says n

Doing a health check on a friends 2013 MacBook air to get it up-to-date.

Installed High Sierra because that is what I get offered when updating ( the Mac is running 10.9.5)

All appeared to complete successfully and did a Restart.

These two screenshots appear to contradict each other. I'm flummoxed.

How peculiar.

The about this Mac window is completely different from the one used by Sierra and High Sierra, they both have tabs across the top.

Go to System Preferences and choose Start Up disk. What does it say?
What does the background picture look like?

Definitely still 10.9.5 installed

As the startup disk says so and the background is the wave.

But the install of High Sierra proceeded without error and took quite a long time to complete as expected.

The end result is is this screenshot which as you can see says it has successfully installed.

Who should I report this too ? Is there a workaround ?

thanks

I have never seen this before

The only thing I can suggest is that you re-install High Sierra.
I'll look around some more and let you know what I find

But can’t reinstall as updater thinks it is already there
by esanITy / May 6, 2018 10:48 PM PDT

As you can see from the screenshot I included earlier as the software updater thinks High Sierra is installed (even though it isn’t) I can.t see how to initiate a reinstall.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
