I try to increase a transaction fee for transaction wich was made with flag replace-by-fee and cant do it. For this transaction i have set explicit address for change. Bitcoin Core QT ver. 0.17 Mac OS High Siera 10.13.6

Do you get this error?

Transaction does not have a change output (code -4)

yes

If you have set a manual change address (with fundrawtransaction, etc.) unknown to your wallet as change, the bumpfee call has no clue which output to reduce in order to increase the fee.

bumpfee currently isn't very clever. I think it won't work with transaction without a change output.

Try to manually create a replacement-transaction with createrawtransaction.

I think you'll have to use an address from getrawchangeaddress
