Sorry, how can I run Bitcoin Core with "-zapwallettxes"? I use the Mac version: do it exist a terminal command line version?

My wallet don't let me the abandone option available for the 2th transaction. The 1th is yet shown as abandoned ...

If I don't pay any accelerator service, how long I should wait for the pool delete my transaction so I can see my BTC as available in my wallet?

Hi,
the situation didn't change. Is there someone that cam help me?
Tx a lot

Hi to all,
09/12/17 I entered with Bitcoin Core 0.15.1 for Mac one transaction with to low fee (I'm a BTC wallet inexperienced user   ) transaction ID: 7e4c59354b46d75a2f2df689dc0b03905aab85acfcacd02f1acc2e40c82d38de

16/12/17 I abandoned that unconfirmed transaction (after the related menu option became available) and re-entered the same transaction with an higher fee
transaction ID: 3c25bb7e62833533c87aea751f8998701ac6771fc6a684fad63a2126c49c0962

My wallet now display the 1th transaction as abandoned and the 2th as unconfirmed, but on https://blockchain.info/ the 1th transaction is displayed as unconfirmed and the 2th as "not found".

Please, what should I do to exit from this vicious circle?

Thanks in advance
