Is notification feature working on macbook?

[CiroGomes]

I have activated, tested pushing some notifications and none worked.
Have I done something wrong? Do I need to set something up?

If you are using Safari my answer is I don't know. I believe Apple were supposed to add support for web push notifications some time this year finally though I'm not sure if it happened yet (and if there's any incompatibility with the site).

It might be worth trying with Chrome/Firefox if you have not yet.
