Yes, you can use Minecraft from Windows to Mac. All you need to do is copy the folder %appdata%/.minecraft from Windows to /Library/Application Support/minecraft on MacOS. Then simply run the minecraft .jar file.
For PC players using the Java Edition of Minecraft, you can open the command console by hitting the "/" key. This will let you add any command and use cheats in Minecraft. The command for spawning the Blue Axolotl is "/summon minecraft:axolotl Variant:4."
As for Minecraft Bedrock Edition players, you can add a Blue Axolotl to their world by opening Chat and Commands and inputting, "/summon axolotl minecraft:entity_born." Within several moments, a Blue Axolotl should successfully appear. Additionally, both Java and Bedrock should bear in mind that Axolotls need water to thrive and will not survive very long on dry land. Therefore, ensure you are spawning the cuddly creature near a body of water for the Blue Axolotl to swim in.
