Unable to sync new Iphone SE with Itunes

OK, thanks.

That’s not iTunes - it’s now called Music. Admittedly it’s iTunes-like. Your iMac is current.

Try this then.

If your computer doesn't recognize your iPhone, iPad, or iPod - Apple Support

opened up iTunes in iMac

The current release of MacOS, MacOS Catalina, does not contain iTunes. Therefore, we know your iMac is not using current software. The question is how old all your software is.

• What iOS version does your old iPhone SE use?
• What MacOS version does your iMac use?
• What iTunes version number does your iMac use?

What exactly happens when you attempt to sync your new iPhone SE with iTunes?

Yes, I know. I did read the thread above. The computer does not recognize the new iPhone. The article above applies.
