Note 8 Connecting to Mac

Hi I'm wondering if anybody is able to help.

I have a Note 8 and would like to connect it to my 2017 iMac running High Sierra. When I plug my Note 8 in it automatically launches Android file transfer and file transfer usb mode on the phone but I get "Could not connect to device, Try reconnecting or restarting your device". The phone is in the correct mode and knows it's connected to a Mac as it advises I download AFT or Samsung Switch.

The Note connects to a older 2009 MacBook without a glitch and the only difference being I get a Allow prompt every time it connects to the MacBook and not the iMac. (This seems to be the issue not having an allow prompt)

I have reinstalled AFT and are using the supplied USB C cable.

I previously owned a Nexus 6 which connect to the iMac with out issue.

I have just tried a Galaxy Xcover 3 and same issue so it seems to be a Samsung related problem
Many Thanks

I don't have a Note8, but if you go to the "settings", are there any other options regarding USB connections?

You may have to enter developer mode on the Note 8.
Are you trying to move information from the Note 8 to the iMac?
