2 quick Q's: High Sierra Auto Update & 2017 iMac Screen Angle

[Samurai Shampoo]

Hey, how are you guys doing?

I have a question regarding High Sierra.

Does this OS update automatically or do I need to download and install it manually? I got no notification for updates besides iMovie which I don't even use.

And another question regarding the 2017 5k iMac.

After taking it to an Apple Store to have them take a look at the extreme fan noise of my iMac the joint of screen makes a kind of rough scrubbing sound when adjusting the angle.

The apple store guy wasn't very cautious with the iMac and I was on the verge of telling to slow his role and not treat it like it's sack of rice.

The sound it makes when adjusting the angle sounds a bit like rough metal scrubbing on metal.
Am I going crazy or was this a smooth / no sound prior to that event? Is yours making that sound when you change the angle?

Thanks in advance.

Download, 1GB and about 20 minutes or so to install. Several restarts during the process. Go to the App Store and hit 'Updates'. Folks saying the usual message about updates is no loinmger in use.
