Downloading MyCrypto wallet 1.5.6 for Mac OS allowed me to send ETH and tokens to the new address! Problem Solved!

Having lost the seed, the situation is pretty dire (we should always remember that having a hardware wallet does not save us from having to pay attention to the weakest link: the recovery seed storage itself). The work around may be that of searching for older (safe) versions of third-party wallets that link to Trezor, but that do not require the firmware to be up-to-date.
