    Hello,

    Is this supported or available on my 2015 iMac? I was asked to find out as if they are, I need to disable them (although I have no idea how to, and I had not actually heard of them this morning!) I would be grateful of any pointers.

    Thanks

    My 2008 MBP apparently supports it, however is only available if set to configure Manually. If on Auto then MTU defaults to 1500. If is set to Jumbo (9000) then change to Manual, change the MTU to 1500 and then set back to Automatcally.
