Some questions regarding new iMacs connectors

In most cases you only need adapters to connect older devices. For example if you have a USB 2.0 or 3.0 device you can find adapters for less than $15 on Amazon. If you have old Thunderbolt 1 or 2 devices, then you need a Thunderbolt 3 to Thunderbolt 2 adapters, Apple sells one. If you Thunderbolt 3 devices, they are the same as Thunderbolt 4 so no worries there.

Apple is extremely practical and leads the way in innovation. By going to USB C and Thunderbolt 4 they are providing you with MUCH MUCH faster interfaces. I understand you have old slower peripherals, however when you eventually upgrade then you will appreciate the speed.

Apple has lead the way with many innovations, dropping DVD drives in iMacs 10 years ago, and diskette drives very long ago, why because they looked into the future and saw that those devices were not included. There solutions available to you that solve your temporary problem and there is no need to whine.

$30 add-on. Cheers!

Also I need to be advised regarding a hub model I can plug normal usb devices and RJ-45 Enternet plug to one box.

That is probably a dock, not a hub.

I am a +1 on OWC docks, easy to connect and setup and OWC specializes in Macs so you know their products work, they also provides excellent service.

The iMac’s external power adapter has an integrated RJ-45 socket for Ethernet.

Only the $1499 configuration and up has Ethernet integrated into the external power supply.

I noticed that too but hopefully it’s an add-on option. We will know tomorrow.
