What fee do you charge to do this if it works.
it has a very low fee of 4.818 sat/B, unfortunately for viabtc free accelerator you need minimum 10s/B
on your old mac, I hope you still have access to it, run the old bitcoin core and export the private key
then I suggest pick a new wallet, import the address (using private key) and re-send your transaction with higher fee
