Defeat Korrina. You will need to complete some of the story before you get access to Mega Evolutions. Completing these tasks will give you the item you need to perform Mega Evolutions. Obtain the Rumble Badge from Shalour Gym by defeating Korrina.

Get the Mega Ring. Go to the top of the Tower of Mastery after the battle and talk to Korrina again to receive the Mega Ring.

Upgrade your Mega Ring. The upgraded ring isn't necessary for all Mega Evolutions, but is required in order to find the hidden Mega Stones.

Select "Mega Evolve" during a battle. You can only Mega Evolve during battles, and only one of your Pokémon can Mega Evolve per battle. The Pokémon will stay in its Mega form until the battle is over or it faints. It will stay in its form if you switch it out during battle.

Defeat Norman. You won't get access to Mega Evolutions until a little ways into the story. Defeat Norman, the 5th Gym Leader, and then make your way to the next town. You'll meet Steven and then head to Southern Island. Defeat Team Aqua/Magma to receive the Mega Bracelet.

Find the Mega Stones from X and Y. All of the Mega Stones that were available in X and Y can be found in Alpha Sapphire and Omega Ruby as well. Many of them require that you defeat or capture Groudon or Kyogre, which happens towards the end of the game. Some Mega Stones require you to meet other conditions. For example, Lucarionite requires that you obtain the Master Rank in all five categories of a Pokémon Contest, and then you'll need to defeat Lisia. Different stones have different requirements.

Find the new Mega Stones. Alpha Sapphire and Omega Ruby introduce a number of new Mega Stones for old and new Pokemon. Many of the following stones require you to complete some sort of requirement. For example, you'll receive Latiasite/Latiosite from Mom in Littleroot Town after you've met Zinnia in the game. Most of the stones below will not become available until after you've captured or defeated Kyogre or Groudon.

You'll receive the Diancite the next time that you enter a Pokémon Center. ** Rayquaza does not use a Mega Stone to Mega Evolve. Instead, it needs to learn the move Dragon Ascent.

Have the correct Pokémon hold the Mega Stone. If you want your Pokémon to be able to Mega Evolve, it will need to be holding its Mega Stone. You can't do this during battle, so make sure that you've equipped it beforehand.

Choose the "Mega Evolve" command during battle. This will cause your Pokémon to perform its Mega evolution. If you have multiple Pokémon that can Mega Evolve, only one is able to per battle. The Pokémon will stay in its Mega form until you have finished the battle or until it is knocked out. You can switch the Pokémon out and then back without having to go through the Mega evolution again.
