Thank you very much for your help, regardless of the outcome here.

I will look again into trying to get from Time machine, an old copy of my wallet for the Mac

Any further suggestions are very welcome!

  **************************************VERY SPECIAL UPDATE**********************************************  

With the positive thoughts I have had since buying a Trezor wallet last week......perhaps, or just the price now of BTC to fiat {all time high $7500} -

I thought I would just try a transaction from my wallet, to any of the Mac wallets I created, to get going forward with this before going to TM.

I loaded the TX into the new wallet I created with your instructions [Restore from seed, with a new 2FA]

This was the one I tried made on my Mac in the newest version visiable:
   wallet type (2FA)
        x1      xpub69Y ...6fDY       +
        x2      xpub69Y...A           -
        x3      xpub661...zM        #

And it allowed me to Sign, and Broadcast the TX.

I now have the value $1.1 of BTC in my new Trezor wallet  

It worked!   Many many thanks for guiding me and helping me with my greater understanding of how transactions work HCP   and Abdussamad  


Now this test transfer is over, I shall transfer the rest of my BTC and endeavour to try and get my Bitcoin cash and Bitgold!
