the confusion was probably my initial explanation somewhere along the line, sorry for this.

Let's just just recap. ...

I have BTC in the Linux wallet I wish to spend, which produces tx's I cannot get signed on my Mac, where originally I did.

I put in the Subject of the thread, how can I get rid of the multisig feature, and by this I mean how can I spend/send the BTC from the Linux to anywhere else, as I am stuck with unsigned/broadcastable tx's. I was thinking that I could restore/sweep or whatever into a new wallet, and set up just a standard one to replace The current Linux one I referred to as multisig, so releasing my BTC.

The Mac (2fa) wallet can be ignored in that I had already removed all the BTC from it.
