iMac 2017 with High Sierra (crashes and beachball problems)

[tony1002]

Good Day,
I got a new iMac 2017 thats been an nightmare for me. I always get the beachball. I am even on the desktop creating a new folder or renaming something, I get beachball and everything crashes. Force quite doesnt work either says finder not responding but I cannot restart it. Only way to do this is by holding down power button. Sometimes when using preview I get beachball then I see finder is frozen again.
What I tried:
1.Clear App Caches
2. Disconnect all USB devices or anything not necessary
3. Hardware diagnostics (found nothing wrong with the hardware)
4.Took in to Apple Store (They did reinstalled OS X) I took it home and after using the computer for 30min, the same behavior came back
Apple is saying nothing is wrong with the computer.

I am really really stressed because I need to get work done and cannot continue using this machine in this way. my 7 year old iMac works much better then this.

Any advice would be wonderful.

Thank you

If macOS has been installed from scratch, fully reformatting the drive, then I see no way software could be the cause of your issue, unless you reinstalled a bad piece of software afterwards

I honestly dont know what else to do. Apple is saying its the software I Use and the me behavior not their fault.

After reformatting your drive and reinstalling macOS, what software do you then install and use?

Reformat your drive once more, and use the base macOS with no extra software and see if the issue persists

Were you able to demonstrate the issue at the Apple Store before they reinstalled?

What is the storage in your iMac? HDD, Fusion or SSD?

Are you dealing with an Apple Store or a Reseller?
