今まで means 'until now' and can be used in both positive and negative sentences, while 未だかつて is only used in negative sentences and is more emphatic.
一いち度ども
一度も means 'not even once' and is more colloquial; 未だかつて carries a stronger, more formal emphasis on the entire past up to now.

Compound of 未だ (imada, 'still, yet') and かつて (katsute, 'once, before'). The combination reinforces the sense of 'never yet' in negative contexts.
