Cannot really see, but generally white fluff on Apples means American blight. Which is neither American nor a blight. It is an insect which covers itself with a waxy coating. You need to dissolve the wax before any insecticide can kill the insect. Various things. If only a few then wash them off with soapy water and a soft brush, Or wipe them over with Methylated spirits, avoid getting it on the leaves. Or use a Horticultural soft soap insecticide according to the info on the bottle.
I've had the same on my apple this year for the first time. I think they're woolly aphids. I've given mine a full-on summer prune so most of them are now composting

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.

Since pruning my tree, then remaining fluff has disintegrated.
I'll give it a winter wash with Vitax tree wash
