Minecraft does not start despite deinstit?

I have not played Minecraft for a long time, and when I wanted to start it today, it just does not start. I play on Mac, and have already reinstalled the game, what can I do?

Restart everything

I already have the game already uninstalled, it does not start, I click on the icon, and it happens nihts.

Do you have Java installed and up to date?

As far as I know, so I installed it, but it did not work, what's the latest?

Without Java, Minecraft will not work, maybe your version is too old. https://java.com/.../download/
Install it again, a try is worth it.
