Where did you hear something about an apple?
Feed the horse to increase the likelihood of taming it. This is usually unnecessary, but try if the horse keeps throwing you off and you are frustrated. Just hold the food in your hand and right click on the horse. This takes up your food, but makes future taming easier.https://de.wikihow.com/In-Minecraft-ein-Pferd-z%C3%A4hmen#_note-6 Each unit of sugar, apples, and grass will help a bit and add another 3% to your chance.
Golden carrots add another 5% to the chance, and Golden Apples add 10%. However, you should save them for breeding as described below.
Quite often go up (right-click with the empty hand), until it does not throw you down someday.
